Required tool:
Cuff 32x50-10 with spring assembly, 2 pcs .; Inserts (plastic or bronze), 4 pcs .; Ball bearing gasket (cat. No. 31-0121238), 2 pcs .; SHRUS-4M; Cold welding;
We install a new cuff of the semiaxis in the ball joint. The orientation of the cuff is carried out along the sealing spring - it must stand on the side of the main gearbox (ie, when installing, the spring must "look" at you). We install the gasket on the end of the ball joint. 
In cases where there is slight wear or deformation of the pivot support along the inner hemisphere, it is allowed to use composite materials to fill the damaged areas. In this case, it is necessary to install the pins and liners without waiting for the polymerization of the composition. 
We install new liners (plastic or bronze) in the bearings of the pivot on the ball joint and apply the SHRUS-4M grease to the inner surface of the liners. 
Step 14. Assembling the steering knuckle
Required tool:
Litol-24, 0.5 kg per side; SHRUS-4M, 50-75 grams;
Install new thrust washers knuckle joint into the ball joint and the knuckle housing. 
Before assembly, on the inner surfaces of the steering knuckle body and the ball joint, we apply Litol-24 grease, about 0.5 kg 
and insert a semi-axle with a hinge of equal angular velocities, on which SHRUS-4M is applied up to 100 grams. 
Step 15. Installing the ball joint
We put a ball joint on the semi-axle, while making sure its orientation is correct.
The bottom of the ball joint is determined very simply: there are three holes on the flange on the bottom side, and two on the top. We recommend that you notice the orientation of the steering knuckle housings during disassembly, for example, by punching or paint.
We draw your attention to this, since the knot is assembled in any combinations and it is easy to make a mistake. 
Step 16. Lubricate the king pins
Required tool:
Pivots; SHRUS-4M up to 30 grams ";
Lubricate the tapered surface and thread of the clamping sleeve, lubricate the friction surfaces of the pivot with SHRUS-4M grease 
Step 17. Tightening the clamping sleeves
Required tool:
Pivot key; Head 27; Torque wrench up to 30 kgf * m; Soft (copper or aluminum) mandrel; Hammer; Calipers;
We insert the pins into the threaded holes of the steering knuckle body and wrap the clamping sleeves until the pins stop in the supports. If you have installed pivots with a channel for lubrication, then for further work you need to unscrew the grease nipples from them with a key "8" 
The steering knuckle body is centered relative to the ball joint with an accuracy of 0.2 mm from the ends of the knuckle body nodules, using a pivot wrench with a "27" head

2 - the body of the rotary fist;
3 - Expanding sleeve;
4 - Kingpin;
5 - Insert;
6 - Hinge of equal angular velocities;
7 - Ball support;
A and B - Controlled dimensions, A = B
Alternately increasing the torque by 2-3 kgf * m, using torque wrench (periodically checking the symmetry about the ends, the deviation should not exceed 0.2 mm), tighten the clamping sleeves with a final torque of 20-25 kgf * m.
With a sequential increase in the torque of the clamping sleeve, every time soft mandrel strike with a hammer (video) along the axis of the pins on both sides.
It is necessary to ensure the accuracy of the symmetry of the installation of the ball joint of 0.2 mm, relative to the ends of the beads of the steering knuckle body.
Measure with caliper.
This centering is necessary for the correct operation of the axle shaft seals and to reduce the load on the constant velocity joints.
We draw your attention - after tightening the clamping sleeves with a force of 25 kgf * m, the ball bearing relative to the steering knuckle body rotates very tightly, it should be so. The swing effort is adjusted separately - by tightening the pivot nuts ().
Step 18. Installing the cage and steering knuckle cuff
Required tool:
Litol-24, 100 grams; Head 10
We stuff Litol-24 into the cavity between the ball joint and the steering knuckle housing. 
Then we install the steering knuckle cuff .. 
Install the felt ring (SP134-12-5 ring), which must be pre-soaked with machine oil. 
Install the steering knuckle cuff clip 
Using the "10" head, screw it onto eight M6x12 bolts
Step 19. Adjusting the stopper bolt
Required tool:
Key for 12, 14, 17; Vernier caliper with a depth gauge (Columbus);
We screw in the stop bolt with a lock nut, set the previously measured height on the caliper and fix it with a 17 "key and a 12" key.
Tighten the M10x1x16 bolt with a 14 "wrench. 
Step 20. Installing the spacer and steering knuckle arm
Required tool:
Head 19; King pin pad (cat. No. 3160-2304028), 3 pcs .; Swivel arm gasket (cat. No. 3160-2304029), 1 pc.
Install the gasket, pad and screw on the M16x1.5 nut with a flange on the kingpin. 
We install the gasket and the steering knuckle lever, the expanding bushings and screw them onto four Ml2x1.25 nuts using the "19" head and screw the M16x1.5 nut with a flange onto the pivot. This photo shows a variant of the steering knuckle lever for UAZ-374195 vehicles and its modifications 
Step 21. Installing a steering knuckle with a semiaxis
Required tool:
Key for 14
We screw rounded fist with a semiaxis to the flange of the casing of the semiaxis on five special bolts Ml0x1x30, on two of them, having previously put on the rotation limiters, with a key "14" until it stops.
Attention, after running 200-500 kilometers, repeat the tightening of the indicated five special bolts Ml0x1x30 
Step 22. Adjusting the ball joint
Required tool:
Head 24
The UAZ Patriot SUV is equipped with a steering knuckle in the front suspension design. This element is present on all vehicles, since without it it is impossible to turn the front wheels. The main purpose of the steering knuckle is the ability to deflect it at a certain angle from the longitudinal axis. Due to this possibility, the front wheels are turned at a certain angle. But besides this, the steering knuckle is also designed to be able to install a wheel hub with bearings, a brake caliper, a brake shield and a number of different sensors. Also, this device is a connecting element of three systems:
- front suspension;
- steering control;
- brake system.
You can learn more about this element on a UAZ Patriot car in. Today we will pay attention to the lubrication of the steering knuckle of the UAZ Patriot SUV and what you need to know.
UAZ Patriot is a creation of the Russian car industry, whose heart is in the city of Ulyanovsk. Of course, in some ways the domestic UAZ Patriot SUV is inferior to foreign ones, but in some it is not.
One problem is that a mechanism such as the steering knuckle does not receive enough attention from the factory. In its design, there is not that little, but practically no lubrication at all, which leads to unfavorable consequences. Already on the first day after purchasing a new SUV, motorists may notice an unpleasant sound of metal rubbing against metal. But, of course, such a phenomenon should be eliminated not because of an unpleasant sound, but in order to avoid the imminent failure of the fist.
There are two steering knuckles on the UAZ Patriot car, which need to be serviced from the first day after purchasing an SUV from the passenger compartment. If the product is not properly lubricated, then over time its working parts will wear out, corrode and immediately fail. To protect yourself from unnecessary waste in the near future and your SUV from the need to replace new parts, you need to lubricate the steering knuckle in time, which will be enough for at least 60-80 thousand kilometers.
What is used for lubrication
The actual service life of the part depends not only on the presence in the product lubricant but also on the quality of these lubricants. The steering knuckle and CV joint are under heavy loads, which means they heat up. Therefore, it should be borne in mind that the material must not only have good antiwear properties, but also withstand high temperatures.
The lubricant must also perform a protective function, protecting important structural elements from water, dust and sand. These negative factors, when they hit the steering knuckle, lead to its failure. The presence of a lubricant prevents these factors from entering the design of the device, even if the protective boots fail.
Thus, in order to lubricate the steering knuckles on the UAZ Patriot SUV, it is necessary to use the well-known Litol-24 grease. One device will require about 400 grams of Litola-24. In the process of lubricating the steering knuckle, it is necessary to apply lubricant to the CV joint. For SHRUS it is necessary to use SHRUS-4M grease, which needs about 100 grams for one side.
Lubrication process
To thoroughly lubricate the steering knuckle and CV joint, these parts must be removed, the inner filling must be cleaned if necessary, and new material must be applied. To carry out the work, you must perform the following steps:
This machine node
The knot, which is included in the steering knuckle of the UAZ front axle, is a ball pin. He takes over all the load that falls on front axle while driving. These loads are especially great when driving off-road and rough terrain.
During the operation of the car, this pivot unit quickly wears out, which leads to the appearance of gaps and backlash in the front suspension.
Steering knuckle repair is necessary in the following cases.
- Replacement of liners or packing of the assembly.
- Ball pin wear.
- The steering knuckle is deformed and requires replacement of the ball joint.
Often, steering knuckle breakdowns are caused by poor-quality selection of components installed during its assembly, namely, a discrepancy:
- the diameter of the support and the inserted hemisphere;
- thickness and seat oil seal;
- the thickness of the liners.
Features of prevention and repair
Repair of the UAZ steering knuckle can be carried out both independently and by contacting a car repair shop. Price renovation works will depend primarily on the price of the parts to be replaced.
The fist dries up
If you have some experience and the necessary set of tools, having studied the instructions on how to disassemble and repair the steering knuckle, it is enough to buy the required spare parts and carry out all the repair measures yourself. This will not only save money, but also gain new knowledge about the design of the car.
One must not forget about regular preventive measures, consisting in examining and assessing the condition of the steering knuckle bushings, as well as identifying the presence of play in the front suspension.
Before you start repairing the steering knuckle, you need to familiarize yourself with the features of its implementation.
- If Nyloc nuts are installed, they will definitely need to be replaced, as they have a special coating that prevents them from unscrewing and loosening the clamp. After screwing on the nuts, this coating is destroyed.
- Do not put the car on wheels if at least one drive shaft is disconnected from the hub, as this can lead to deformation or destruction of the hub bearing. If it is necessary to move the machine a short distance, the shaft must be returned to the hub and secured with a nut.
- Depending on the car model and the year of its production, the UAZ fist has two modifications, in one of which the hubs are solid, and in the other they are hollow, which is determined by the presence of a hole.
Before proceeding with the repair, the following manipulations are carried out.
- The car is put on the hand brake.
- Under rear wheels put stops that will prevent the machine from moving.
- The front of the car is lifted with a jack or winch and fixed on stops.
Only after making sure that the front of the machine is securely fastened and that it is impossible to move or break off the stops, you can start removing the wheel.
The process of dismantling the wheel and brakes
To remove the wheel, it is necessary to carry out the operations in the following sequence.
- The cap is removed from the wheel hub, the R-shaped bracket is removed, and the locking head is dismantled. On the drive shaft, loosen the nut that connects it to the hub. After that I remove the front wheel.
- If the car model is equipped with ABS system, there is a sensor on the wheel that must be removed.
- The nut that secures the drive shaft to the front suspension hub is twisted.
- The brake caliper is attached to the steering knuckle with two bolts, which must be unscrewed and disconnected from the brake disc the caliper, after which it is tied to a spring on the front suspension.
- Before proceeding with the removal of the brake disc, it is necessary to note its position in relation to the suspension hub. The line can be applied with chalk, but it is better to use white paint so that the line is not overwritten during repair work. Only then unscrew the fastening screw and remove the brake disc.
Fist lubrication
To facilitate the process of dismantling from the steering knuckle, it is necessary to use a special device with which the suspension springs are compressed and fixed. For this, cables are used, for example, as on tool 0903 AF. The procedure for compressing and fixing the springs is as follows:
- there are two holes in the upper part of the rack, one of which is inserted with a cable;
- then steering column turns and a second cable is inserted into the second hole;
- free ends of the cables cling to the lower edge of the cup;
- the upper ends, inserted into the rack, are fixed by screwing bolts with a diameter of 6 mm into the holes.
The steering knuckle is designed to change the direction of the vehicle by increasing pressure on the steering levers, which ensures a change in the angle of the wheels.
This part of the vehicle is one of the most significant. The steering knuckle (UAZ, Volkswagen, BMW - it doesn't matter) is the basis for the hub and is attached to other parts due to Usually two types of parts are distinguished: with a hub and with a spindle.
Estimated market value
There can also be a left or right steering knuckle. Outwardly, they are almost identical, but since these details are directly related to it, it would be best to play it safe. On one of them there is a bipod, on the other there is no outlet for longitudinal thrust. It is for these reasons that their cost differs.
Auto parts can be purchased at car dealerships, car markets, ordered on various sites. The right steering knuckle costs about 8,400 rubles, on the left the price starts from 6,530 rubles. These are approximate prices for kulaks for UAZ-31519.
It is not worth saving, even if the cost of domestic spare parts is higher than that of Chinese ones. It is more than likely that an expensive part will last much longer.
How to make the right choice?
When buying on the market, you should pay attention to the seat where the steering knuckle bearing is installed (the inner race should sit tightly without a hammer), as well as appearance details: whether there is corrosion, whether there are cracks or bends. Any crack later can turn into a very difficult problem to solve.
Part design
Parts of the steering knuckle include the hub and brake disc. In addition to the most important part, they are included in the basic spare parts kit for steering.
But the most important on this list is the steering knuckle. UAZ will serve as a car, on the example of which a scheme for removing a fist will be built.
Replacement and repair
Despite the seeming complexity, replacing such a part as a swivel fist is not particularly difficult. The first step is to put vehicle on the handbrake, then place the anti-rollback wheels under the rear wheels and raise the front of the machine with a jack.
- Remove the brake disc.
- Unscrew the trunnion fastening.
- Remove it assembled with the wheel clutch, brake disc shield and hub.
- Remove the axle shaft.
- Separate the rods from the steering knuckle itself.
- Remove the bolts securing the ball joint to the axle housing flange.
- Remove the wheel stop.
- Prying off with a fitting, press out the shank of the ball joint from the axle shaft housing. To do this, use a puller for ball joints.
- Carefully remove the required part, in our case the swivel fist.
After replacing the fist, the actions should be performed in the reverse order, not forgetting to put the rotation limiter in place. For repair, the steering knuckle should be clamped in a vise and disassembled by unscrewing the cuff mounting bolts, a stop bolt with a locknut. Next, the cuff clip and the felt seal are removed. At the end, the ball seal is removed.
The most difficult thing is over, what is left is what requires attention. The ball joint is carefully removed. This is roughly how the repair and replacement of the steering knuckle takes place.
Replacement of pivots
There are also parts that need to be replaced from time to time - these are the pivots. To replace them, you will have to remove the steering knuckle and clamp it in a vice. After that, using a mandrel, knock out the pivot bushings and thoroughly clean the passages for lubrication and for a replaceable spare part in the fist.
After the mandrel, new bushings are installed so that the holes in them coincide with the holes on the fist, and the open ends look towards the beam fixed to the front axle.
At the same time, both bushings are unrolled to the required diameter. After that, the bushings are cleaned and a thin layer of grease is applied. Then, after lubricating the O-rings and ducts in the knuckle bosses, the rings themselves are installed.
Possible damage
Despite the fact that the steering knuckle is one of the most "long-lasting" parts of a car, its damage is just a matter of time. Sometimes the protective casing can crack, giving access to dust and sand, so it is worth checking its integrity from time to time.
If it fails, the best solution would be to replace it. Often you can see oil drips on the steering knuckle, indicating that the oil seal / axle shaft joint is loose. Here you just need to change the oil seal for a better one. Such problems are common in vehicles that have been involved in an accident.
How to protect against wear
Those car owners who recently bought a UAZ often hear unpleasant sounds when turning the steering wheel, as if metal rubbing against metal without any lubrication. This is often the case. How can you protect your fists on a domestic car? This is where the ubiquitous lithol comes to the rescue.
If there is no experience in car repair, then you can coat the left steering knuckle, like the right one, only on the outside. For people more versed in auto mechanics, this method is suitable: by unscrewing the circular oil seal, move it to the center of the car and add more lithol to the resulting gap.
These operations are performed after cleaning the car from transport paint or polyethylene. You should also check for the presence of a seal.
Steering knuckle design
The most common knuckle design is the so-called "straight cross". Although most of them look almost the same, there are differences in size. One can be a little more, the other a little less.
A swivel fist is usually made of steel. Thanks to this material, such an important part is able to withstand colossal loads. But with all this, the lighter the knuckle part is, the better the shock absorption and handling will be. Therefore, designers are trying to obtain the optimal ratio of weight to strength.
The seats on auto parts are specially designed for attaching dirt protection rings, which do not allow all kinds of debris to enter the hub bearing. The body is designed in such a way that it is convenient to screw the suspension elements onto it.
You may be wondering why most of the article is devoted specifically to the UAZ car? The answer is: because it is domestic car, which has managed to prove itself well - easy to maintain, reliable on the road.
Many people underestimate this car, believing that foreign cars are better, but this is far from the case. In many respects, the UAZ, even produced in the Soviet Union, surpasses many modern SUVs, but, unfortunately, it remains unrecognized.
Although made of steel, the steering knuckle is one of the weak points any car, often due to bad roads... It is worth watching it, because at a crucial moment it is this part of the steering that can help to avoid an accident.
On September 20, 2018, the production of the updated UAZ Patriot SUV began at the Ulyanovsk Automobile Plant. Anyone could watch the assembly of the first car of the 2019 model year live.
In the course of the planned modernization, the UAZ Patriot SUV has become more powerful, comfortable and convenient in everyday use, without losing its off-road qualities.
The main news is that instead of the previous engine, the ZMZ PRO engine is installed on the Patriot. The working volume remained at the same level (2693 cm³), however, the compression ratio of the unit increased and the valve timing changed. We also note the appearance of a reinforced cylinder head, double-row chain and new pistons, valves and camshafts.
As a result of the improvements, power and torque are increased to 150 hp. and 235 N.m (it was 135 and 217, respectively). Moreover, the peak of maximum thrust has shifted to the mid-range zone - to 2650 rpm instead of 3900 rpm. Motor ZMZ The missile defense system meets the Euro-5 toxicity standards.
Five-step mechanical box gear has also undergone modernization. Engineers Ulyanovsk Automobile Plant improved the selectivity of the drive and reduced the travel of the gear lever and the effort on it. The lever itself is now composite and equipped with a damper idle move improving vibroacoustic comfort. The reduction in noise and vibration background is also due to the installation of a new LUK clutch with a driven disc, supplemented by an idle damper. The clutch pedal effort has been reduced by 20% thanks to a new release spring.
After the update, the UAZ Patriot should become even more noble on the go. The cars of the 2019 model year have an improved steering with a stiffer trapezoid and damper from the UAZ Profi model. Pros - increased control precision and reduced backlash when turning the steering wheel. From the Pro, the UAZ Patriot SUV got the front axle with a changed angle of inclination of the pivots and open steering knuckles, thanks to which the turning radius was reduced by 0.8 m.
Improved ride comfort is provided by new shock absorbers at the front and rear, as well as rear two-leaf springs, which are 6% softer than the previous three-leaf springs. In addition to more comfort second row passengers thickness rear stabilizer lateral stability Changed from 21 mm to 18 mm.
The Patriot has improved the soundproofing of the cabin due to the larger area of soundproofing materials on the engine shield. It has also become quieter thanks to the modernized seals in the openings of the side doors, with which the doors also close more quietly. Plus, exhaust ventilation from the inside of the headlining in the luggage compartment has moved to the rear bumper area.
The Patriot has become more comfortable for passengers. They are addressed to the handrails on the A-pillars and B-pillars, which greatly facilitate the landing process. The fact that UAZ listens to the wishes of customers is also evidenced by the fact that a double seal appeared in the opening of the fifth door. With it, when you open the tailgate, water will not get into it.
Note that before and during the broadcast, anyone could ask a question. The most popular ones were answered by UAZ specialists. So, the audience was actively interested in when the Patriot will appear automatic transmission gear. And we got an answer.
There will be an “automatic” on the Patriot, we are now actively preparing. Next year, I assure you, there will be an automatic transmission, ”said the operational director of UAZ Ruslan Gorevoy.
