Installing a new yoke on the propeller shaft is actually not so difficult. Whether the repair will be successful, how long it will take and how long it will last depends mainly on the skill of the mechanic. The editor of the profi magazine tells about the secrets of experienced craftsmen.
Drive shafts have been used in agricultural technology for power transmission for many decades. If you look at the protective and shaped pipes, then they have hardly changed much during this time.
Unfortunately, the changes did not affect the most weak point cardan shafts - crosspieces. Four filigree needle bearings work with increasing loads here, and the need to transfer the load at an angle further reduces their chances of survival. While regular lubrication can provide a relatively long life for these bearings, sooner or later they will still have to be scrapped.
Cardan shaft manufacturers offer repair kits to rebuild these cardan joints. And since the hinges can have different sizes, crosspieces for them are also produced of several types. To avoid mistakes, clean the cross carefully and find the number embossed on it - this is enough to order spare parts. Installation and dismantling can be performed even by an amateur in the shortest possible time - if at the same time he owns several professional secrets. We have prepared a selection of such tricks for you.
Dismantling and inspection of individual parts
When should the spider be replaced?
Timely replacement of the cross is of great importance. If it got to the point that the rollers fell out of the bearing, and the propeller shaft began to make noise, this suggests that the opportunity to easily and inexpensively replace the crosspiece has long been missed. A very simple test: grasp both pivot forks and try to turn them sharply in opposite directions. If, at the same time, a gap is detected between the journal and the bearing, this is a signal that urgent measures must be taken.
Why sometimes new repair kits save the situation for a short while?
An extreme case - serious damage hinge forks. Obviously, this will require replacing them. However, the most unpleasant thing here is that it is not immediately possible to recognize such damage. Suspecting nothing, the mechanic installs a new cross, but it quickly fails. This is explained by the fact that:
- or the hinge fork is bent,
- or the bearing seat is knocked out,
- or the bearing seat is cracked.
Therefore, before installing a new crosspiece, carefully inspect the universal joint forks. It is very difficult to detect fork deformation with the naked eye, so the parallelism of the fork cheeks should be measured with a caliper. To determine the deformation of the fork, measure it in two planes. Damaged plugs must be replaced!
Removing the outer circlips
In small crosspieces, the bearing shells are fixed from the outside with retaining (thrust) rings. To dismantle them without unnecessary problems, you must do the following:
- Clean thoroughly around the ring with a scraper.
- Place a rod on the bearing shell and hit it hard once to dislodge the ring.
- Remove the ring using suitable pliers. Tip: be sure to hold the ring with your finger so it doesn't bounce to the side!
Removing the inner circlips
Despite the fact that these rings are buried and it is not so easy to get to them, their dismantling and subsequent installation are not the most difficult operations. They are usually quite easy to work with as their seats do not corrode and remain well oiled. To remove these rings from their seats, you do not need special pliers, but just a small screwdriver. Reverse mounting is just as easy.
Knocking out bearing bushings
There are several ways to do this, some of them are quite complicated. So, the fork can be clamped at an angle in a vice and push out the sleeve using the end head fixed in the same place. We find this method more elegant: take the outer hinge fork (the one that is closer to the tractor) and place the shaft with the other end on the edge of the workbench (the bearing bushings of the inner fork should be vertical). If you now knock on the inner fork with a hammer, you will notice how the top bushing gradually comes out of its socket with each blow.
Complete dismantling of bearing bushings
To speed up dismantling, the fork with the half knocked out bushing should be clamped vertically in a vise. Now, using the pry bar as a lever and resting it on the lips of a vise, raise the fork. After one bearing sleeve has been removed, the forks can be disconnected.
Removing the crosspiece from the outer fork
Clamp the outer fork in a vise so that the transverse cross with fork cheeks rests on the lips of the vise. If you now hit the fork with a hammer, the upper bearing sleeve will begin to pop out of its seat. The opposite sleeve is knocked out in the same way or with a rod.
Bearing reuse?
If for any reason you need to disassemble an undamaged universal joint with working bearings and then reinstall them, pay attention to the following nuance: before starting dismantling, take a grease gun and fill the bearings abundantly with grease. This will keep the needle rollers in place and will not fall out of the bushings.
Installation of a new crosspiece
Mounting bearing bushings
Remove the bearing bushings from the cross and fill them with grease. This will almost certainly prevent the rollers from misaligning during installation. Now press one bushing into the inner yoke of the universal joint - but so that it fits into its seat about three-quarters of the way!
The opposite bearing sleeve is also inserted using a vise. Take your time so that excess grease can drain out through the threaded hole of the grease nipple.
Lapping bushings with a hammer
In order for the bearing bushings to be at the required height and there were no problems with the subsequent installation of the retaining rings, the inner surfaces of the cheeks of the fork clamped in a vice should be tapped with a hammer.
Pressing in with a nut
If the bearing bushings are not fully seated in their seats, place the nut between the bushing and the vise lip and gently tighten the bushing again. Repeat this procedure for all bushings and screw in the grease nipple.
Everything worked out? Check the ease of movement!
After completing the installation, check the ease of movement of the universal joint. Take the shaft in your hands so that the hinge hangs freely. Now turn the shaft and observe the joint. Is it really moving completely freely, or is it squeezed at some point? If the latter, then you need to take a hammer and gently tap both cheeks of each fork.
This removes the pinching and makes the bearings easier to move. If one of the hinges is still pinched, this most likely indicates a deformation of the cheek. And here there is no longer any salvation - the hinge has served its purpose!

The cardan shaft is the most complex and irreplaceable transmission unit for all four-wheel drive or rear-wheel drive cars, which allows the transmission of torque from the engine to the units, drive wheels, gearbox and aggregates. That is why, if the propeller shaft fails, the car cannot be operated and even dangerous. The causes of malfunctions can be different. It may be a violation of rules and regulations. technical exploitation auto, natural wear and tear of units with parts, as well as poorly performed previous repair of cardan shafts. And these troubles manifest themselves in almost the same way: knocking under the bottom, extraneous noise when driving a car, vibration during acceleration, etc.

Cardans, like wheels, sometimes have an imbalance - one of the most dangerous phenomena affecting all rotating parts, including cardan transmission... Unbalance causes vibrations, which cause additional unwanted loads on transmission parts and joints, thereby weakening fasteners and accelerating wear on the mechanism. An unbalanced propeller shaft will damage the rotating parts of the engine, which can be the cause of an accident. That is why cardan balancing in Moscow is a necessary procedure to protect both you and your car from danger on the road. It ensures the smooth running of the car and, accordingly, the safety of the car owner himself.
Vibrations can result from:
Balancing plate loss
wear of the support complete for the bearing
backlash on the receiving flanges of the gearbox, box or bridge
large backlash due to wear in the movable spline connection
deformation of the pipe as a result of mechanical damage or the fall of the unit
gaps or biting due to malfunctioning crosses, outboard bearings or CV joints
dirt, rust, deformations of the fit form an insufficient tightness of the yoke flange to the receiving flanges
The reason for the imbalance can also be deformation after a small accident, and a factory defect, and incorrect installation during repairs. Therefore, it is necessary to detect malfunctions of cardan shafts in specialized service stations in Moscow. Thanks to highly professional modern equipment, combined with extensive experience and the highest professionalism of specialists, when contacting CardanBalance in Moscow, you can be sure that balancing will be done here and the vibration that has arisen will be eliminated at the highest level.
Dear subscribers,
I'll tell you a story about how, before the new year, on December 27, the universal joint of the propeller shaft was torn off.
It was as follows, I was driving at a low speed in a roundabout and at the exit from behind a bend I heard a crack / knock / rumble of metal, the first thought was thrown out by the front-wheel drive ... I think 3/14 tsdets ... no. Well, in order not to be a ram in the middle of the road that interferes with all other traffic participants, it was decided to drive off to the side of the road and put up an emergency sign + a mark in Yandex maps about the breakdown, although I understand that it could be worse. I will not have time to go to the service at about 8 pm, and everything rattles / knocks dumbly, but I am in no hurry to call the tow truck, I thought I looked started moving forward / backward there is no oil, the drives are spinning, the wheels are level. There were about 3-4 services nearby, thanks to my father for his help in monitoring where you can bring in so that a verdict was made to replace the part that ordered to live a long time)) The guys were already going home everywhere and there was no place on the lifts, it was proposed to drag it and leave it for the night, and with mornings will look. Ok, decided to eat myself, turn on the emergency gang, cut two solid ones and drive about 200-250 meters with a clatter / rumble of iron in the front suspension at the speed of a snail and leave it until the morning, by 10 o'clock they should carry out a diagnosis. I came and left and went home, I am not in the mood, I think how much I got and where to look for spare parts on New Year's holidays. Arriving in the morning, they show me the removed propeller shaft whose front crosspiece has collapsed, the decision to look for a used one or a new one, by the way, a used one costs from 6 to 10 thousand rubles. and it is not clear how much it went through, the new one is from 30 to 40 thousand rubles. and this is not with the officials (there are about 70-80 thousand). I knew that there are offices engaged in the restoration of certain spare parts and cardan shafts are no exception, I find an office in Lefortovo, I call they say come, we will do everything)) Cardan in the film and in the trunk, I myself go to front wheel drive having turned on 2WD, there are no errors, everything is ok, the guys found them quickly located in the industrial zone, but next to the checkpoint. I really liked the approach, the quality of work, fire in the eyes and the desire to earn in practice, which they know how to do very well. The cardan shaft was hung on the table, the front crosspiece was disassembled, welded on, grinded, cleaned, put on the cardan, balanced on special equipment, and put in place. In time, it took about 1-1.5 hours all together, a discount of 1000 rubles for Nissan x-trail(+ Renault Koleos, Nissan Qashqai).
P.s. The guys are really only engaged in the restoration of cardan shafts, this is their main and only job, so they are professionals, I advise))) (cardan-lefortovo)
