1. In addition to obvious safety, the Kia Optima chassis is responsible for a comfortable ride and good handling. The most dangerous thing is that in this case there will be a high probability of loss of control, with the next collision with an obstacle that has arisen on the road. Only regular diagnostics of the Kia Optima chassis will help to avoid such a situation.
Diagnostics of the Kia Optima chassis includes checking the elements:
- springs and shock absorbers;
- levers and supports (bearings from above, silent blocks from below);
- Kia Optima stabilizer bushings;
- steering rods and rack;
- wheel bearings;
- CV JOINT.
Diagnostics of the Kia Optima chassis should be carried out regularly, even without showing any hints of a malfunction. It is better to do this on a lift, but it can also be done on an ordinary flyover or observation pit.
3. It is important to remember how the Kia Optima behaves in good condition, then any future malfunction will be obvious. To understand that something is wrong with a car, you do not need to be an experienced driver, and even more so, an auto mechanic.
Most often, the following signs of malfunctions of the Kia Optima chassis occur:
- the sudden appearance of noise, knocking, bouncing of the Kia Optima chassis, which can both disappear and remain even on a completely flat road;
- too large rolls when cornering and noticeable swaying of the body when passing bumps or when braking;
- arbitrary steering to the side, Kia Optima leads away when driving straight;
- uneven tire wear.
If you hear a crunch, especially when cornering or with sharp acceleration of the Kia Optima, then we can almost say with complete certainty that the reason lies in the malfunction of the CV JOINT of the Kia Optima, the so-called grenade. A squeak most often occurs after replacing the stabilizer bushings, often this indicates a poor-quality bushing.
5. If Kia Optima began to drift aside, more often it happens after hard passage of pits and potholes, then you may have to do similarity disorder (wheel alignment Kia Optima). V best case this will eliminate the trouble, at worst, upon impact, something could bend, starting from the steering rod and ending with the steering knuckle.
In the event of at least one of these signs, it is necessary to diagnose the Kia Optima undercarriage as soon as possible. Even the regulations explicitly prohibit operation with a faulty suspension, not to mention the fact that it is simply dangerous.
6. Not replaced in time Kia Optima suspension silent block, which is not so expensive, can lead to damage to the lever, with a price of one hundred dollars. Many drivers drive without paying attention to the sounds that appear in the chassis of the Kia Optima, and drive until the sound becomes completely critical, or until something simply falls off, this approach is simply absurd.
7. Periodic visual inspection of the Kia Optima undercarriage will help save money, after all, if you find a cracked boot or cover in time and make a prompt replacement, then the element that was protected by the boot will last longer. If, on examination Kia Optima an already torn boot was found, then you can be sure that soon this suspension element will need to be replaced.
After checking all the anthers, you should start diagnosing the Kia Optima front suspension elements. The front suspension is more complex than the rear, it is subject to heavy loads, as a result, it breaks much more often. First, we inspect the Kia Optima shock absorbers, they should not have dents or oil leaks. You can also try to swing the shock absorber to the sides, the swing amplitude should be insignificant.
But the easiest way to check the serviceability of this suspension element is to swing the Kia Optima by pressing the corner where the shock absorber to be diagnosed is located. If, after pressing, Kia Optima, having returned to its original state, continued to swing up and down, then this indicates a malfunction of the shock absorber.
8. Next, the springs of the Kia Optima are examined, often their turns break off, so you need to inspect them for cracks and the integrity of all turns. But here you can also determine the functionality of the springs without looking under the car. To do this, you just need to pay attention to the clearance of the Kia Optima, if the car has become noticeably lower, then this already indicates a malfunction of the springs, they sagged and can no longer perform their function properly.
9. Ball and silent blocks are checked only from the bottom side of the Kia Optima. To diagnose them, it is better to use some kind of metal lever to make it easier to check everything for backlash, they should not be in a working car. The stabilizer and link supports of the Kia Optima are checked in the same way. To check the wheel bearing, you need to shake the wheel, if there is a play, this indicates a poor condition of the bearing.
The network of specialized technical centers Kia in Moscow carries out high-quality repair of the Optima suspension at affordable prices with a subsequent guarantee.
Diagnostics and repair of chassis
Any repair of a chassis in car services begins with an input diagnostics that allows you to determine its real technical condition, find existing faults and draw up a repair plan. Along the way, the condition of the pipelines of the brake system and the power supply system is also checked.
Repair of the Optima suspension consists of the following operations:
- Visual inspection of the suspension for the integrity of the protective covers of all moving joints, mechanical damage to the chassis elements and the condition of silent blocks, ball bearings, shock absorbers, springs;
- Replacement of all elements of the undercarriage with increased wear.
Replacement of levers, silent blocks
The need to replace the levers on the Optima arises in cases of mechanical damage, or wear of silent blocks, ball bearings or their mounting holes.
To replace the mechanics of auto centers, they use original products, or their counterparts from trusted manufacturers.
Replacing silent blocks with Kia Optima is required when they are significantly worn out, such as:
- Mechanical damage;
- Sagging of the inner sleeve of the silent block;
- Cracks or bulging or bursting of the filler.
The replacement of silent blocks in Kia branded technical centers is carried out using pressing equipment, which guarantees the quality of their installation and reliability of operation.
Replacement of shock absorbers, support bearing
The condition of the shock absorbers directly affects driving safety. So in a car with faulty shock absorbers, the braking distance increases, which is especially critical in emergency situations.
Therefore, replacing shock absorbers with Kia Optima should be done immediately after their malfunction is detected. In this case, both shock absorbers must be replaced on one axis of the car to maintain the characteristics of the suspension.
The replacement of the support bearing of the struts on the Optima is carried out when signs of its malfunction are detected. it can be a creak when turning the wheels, emanating from both the bearing itself, and a characteristic sound from the stuck spring of the strut.
To replace the support bearing, mechanics of Kia auto centers use original parts, or a replica from trusted manufacturers.
All installed spare parts and the service itself are subject to a mandatory quality guarantee.

Replacing the hub, ball Kia Optima
The operation to replace the hub on the Kia Optima is performed in cases where a bearing play appears, or it buzzes. To determine which hub requires replacement, it is recommended to contact the branded Kia car services where mechanics will identify the faulty unit and replace it.
Operating a car with a faulty hub is fraught with unpredictable consequences, since the hub bearing may simply fall apart, which will lead to its seizure.
In cases where the bearing can be changed separately from the hub, the hub bearing is replaced. If the bearing is integrated into the hub, then only the hub assembly is replaced.
When models have ABS system, then the sensor can come with a hub or separately.

Replacing the stabilizer struts
Structurally, the body of the stabilizer is attached by means of bushings to the body elements, and the stabilizer struts to the suspension parts. Therefore, it is recommended to replace the stabilizer struts immediately after detecting their malfunctions, since the associated suspension elements will be unnecessarily loaded.

Getting started tuning Kia Optima, you should understand that improving this car can cost a lot of money. Especially when it comes to finalizing parts from the engine compartment of the 2013-2014 car. Therefore, it is best to retrofit those Optima elements that require it in the first place. This way you will achieve excellent results with the minimum amount spent.
1 Improving exhaust by removing catalyst
The Optima, like most other business cars, is equipped with a direct-flow exhaust system. The design of the latter contains a catalyst - an element with a short service life, but at a very solid price. A catalyst is a kind of filter whose role is to convert toxic gases into harmless ones. Many experts believe that the presence of a catalyst in cars from 2013–2104 is not necessary at all, since since 2010 most car manufacturers have started to use updated front mufflers. They not only suppress the sound, but also recycle the harmful emissions of the car. That is why many mechanics consider the catalyst to be the result of the requirements of Euro-3 standards and assign it a rather small role in exhaust system auto.
Also, this element serves as another obstacle to the air, which is thrown out by the engine of the machine. Therefore, we will make it easier for recycled vapors to escape, which will increase the Kia's power by 10-15 hp. with. In addition, the Optima engine will sound a little louder and more aggressive, which is sure to be appreciated by fans of street racing. The only drawback of this tuning is that with the removal of the catalyst, the cooling of the emitted vapors will disappear, which will negatively affect other links of the Kia exhaust system. Fortunately, it is not difficult to solve this problem by installing a flame arrester instead of a standard part. To remove the catalyst in the Optima exhaust system, we need to prepare the following tools:
- a set of keys;
- screwdrivers;
- welding machine;
- grinder;
- flame arrester.
First, you need to install the Optima in the inspection pit, so it will be much easier to inspect the car and dismantle the exhaust pipe. After that, we take the keys and begin to remove the Kia tailpipe. In turn, unscrew the fasteners holding the catalyst, front muffler, center pipe and rear muffler. Next, carefully detach the entire structure and set it aside.
The next step is to cut out the catalyst. To do this, we install a small solid object under the intake pipe and cut off the part of the pipe that connects to the catalyst with a grinder. We put the cut piece aside and start sawing off the catalyst from the other side. After that, we weld a flame arrester instead of the catalyst. The last stage of tuning will be the installation exhaust pipe back to the bottom of the Kia with a mandatory check of each fastener.
2 Replacing the struts in the front of the Optima
After finalizing the Kia exhaust, you can begin to improve the car's suspension. Since the Korean model is front-wheel drive, the pillars in the front of the car are most susceptible to wear. As practice shows, it is best to replace standard parts with Optima parts from Kia carnival 2013–2014 c. They are designed for larger cars, which is why they can withstand heavy loads. In addition, Carnival struts are much better springy, which will make the Optima much more comfortable to operate even off-road. For tuning a car, we need to prepare:
- pliers;
- a set of keys;
- mounting blade;
- hammer;
- marker;
- jack.
We lift the car with a jack, and then remove the rubber plug from the upper wheel support. Then, while holding the stem securely, loosen the Kia tie rod joint. Remove the steering rod end from the steering knuckle. We turn the steering wheel to the side opposite from the tip, and use the pliers to pull out the cotter pin. We unscrew the nuts of the fastening of the steering tip and take out the "finger" from the lever with a puller. Further, we do not completely unscrew the nut from the steering rod spacer, insert the blade into the spacer and hammer it along the end of the rack arm with a hammer.
Next, you need to mark the position of the upper adjustment bolt, and then knock out its nut. In the same way we knock out the lower bolt. Then we set aside rounded fist to the side without pulling on the brake hose. We unscrew the fastening nuts of the upper support and remove the Kia strut. After that we install new part and assemble the structure in reverse order. The strut for the second front wheel is replaced in the same way.
3 Methods of improving the salon "Korean"
Since the Optima belongs to the business class, the tuning of the car interior will be more aesthetic than functional. The cockpit has almost all the devices designed to facilitate the control of the model and make the operation of the Kia more comfortable. Among the useful ones that can be additionally installed in the Optima salon, one can also note a mirror with a rear-view camera.
As for the changes in the interior of the cabin, at the request of the Kia driver, tuning can be performed by replacing the standard trim with another, more expensive material. In addition to this, the dashboard and other plastic parts of the interior can be repainted.
Another effective option for tuning the interior is replacing the car seats with sports chairs. There is an opinion that such details are not comfortable and are not suitable for every driver. This is partly true, there are indeed chairs on the market that are designed for heavy loads. Sitting comfortably in them will not work, since these parts are very solid. However, there are luxury sports seats that will suit every car owner. They are made of soft materials and absolutely do not impede the entry and exit of the driver and passengers.
There is nothing difficult in installing the seats. For replacement, it is necessary to dismantle the standard Kia seats, and then clean the seats. Then the mechanism of the fastening lever is degreased and you can start installing new seats. During installation, the levers are wiped lubricant, after which the seats are finally attached to the standard fasteners.
You should be very careful both when buying and installing the seats. If the Optima is equipped with heated seats, then it is worth purchasing sports seats with the same function for replacement. When replacing, we connect the wires exactly as indicated in the instructions.
