Replacing the front wheel bearing in the Nissan X-Trail
Content
Replacing the front and rear wheel bearings on the Nissan X-Trail t30, t31, t32 does not differ in technology, but disassembly and assembly on the front and rear axles is different. Maintenance is difficult and requires special press fit equipment.
When choosing a new part, preference is given to original or analogues of proven brands. The hub (half shaft) is difficult to access, but if you follow the sequence of disassembling the nodes located nearby, you can replace the ball joint yourself.
Where is the wheel bearing located in the Nissan X-Trail
On the Nissan X-Trail with a T30, T31, T32 body, the front ball joint is located in the hub, which is located on the steering knuckle.
Place of replacement in a hard-to-reach place
To get to the bearing, you need to remove the caliper, pads and disc. Disconnect the lower ball joint, move the CV joint to the side, remove the shock absorber strut, only after that you can remove the steering knuckle.
Drum brakes installed in the rear of the Nissan X-Trail
They are attached to the shaft itself. To get to the place of replacement, remove the caliper and remove the drum completely. The cube is then compressed.
Causes and signs of failure of wheel bearings
For Nissan X-Trail bearings are designed for up to 100 thousand kilometers. But this is taking into account the fact that the machine comes only from the factory or when it is replaced with used original products. Premature wear can be influenced by a number of negative factors:
- Vehicle malfunction, sudden braking or driving too fast.
- Unsatisfactory road conditions, little or no coverage.
- Poor quality lubricants or their partial loss.
- If the replacement has already been made, the part was incorrectly selected or its pressing was carried out incorrectly.
- Non-compliance with the load on both axles, regulated for the Nissan X-Trail (transportation of heavy cargo).
- The integrity of the anther is broken, solid particles, such as sand or moisture, have entered the wheel bearing.
- Faulty neighboring nodes.
Signs by which it is determined that the rear part is to be replaced:
- At the beginning of the movement, a sound is heard that was not previously in the Nissan X-Trail. It picks up speed and stalls at high speed.
- Vibration is felt in the back. Wear is approaching a critical point, it is recommended to replace it, otherwise the wheel may get stuck.
- The shaft gets very hot.
- More movement is not possible. If a strong metallic rattle appears, the localization of which is not difficult to determine, the replacement is carried out urgently.
Signs of worn front wheel bearings:
- Howling sound from the side of the problem wheel. It only gets worse as the speed increases.
- The vibration of the steering wheel is clearly felt, in this case an urgent replacement is necessary.
- Nissan X-Trail pulls to the side, the handling index decreases.
- Indirect signs include sudden braking or an increase in speed.
If the resource of the pads is good or the replacement was carried out recently, but the brake disc is heated, the reason may be the wear of the ball joint of the axle shaft.
How to check a wheel bearing
A strange noise has appeared, but it is not yet so obvious that it can be determined by ear which side it comes from. You can independently diagnose the problem on the Nissan X-Trail as follows:
- Raise the body and turn the wheel by hand. If there is a problem on this side, noise or rattling will be heard.
- Therefore, you need to check all four axle shafts. Even by comparison, you can determine which hub needs to be replaced.
- The suspended wheel is taken from above and below by hands and begins to oscillate, thus determining the presence of play. If a party has not exhausted a remedy, there will be none.
Ahead, you can experience the Nissan X-Trail at speed. When you turn to the right, the buzzing stops, which means you need to replace this side with the problematic wheel bearing. The same with the maneuver to the left.

What tools and materials will be required to replace
To replace a wheel bearing on a Nissan X-Trail T30-32, you will need the following tools:
- mounting lever;
- a hammer;
- wooden or rubber hammer;
- pliers;
- a collector to squeeze out the old clip;
- screwdriver;
- lift or jack, wheel chocks;
- ratchet;
- necklace;
- hydraulic press (mandatory equipment for Nissan X-Trail);
- heads and keys on 32.36.14.17, 18.19;
- VD-40.
If the Nissan X-Trail is not new, then a metal brush will be required to treat the working surface of the nodes from corrosion and dirt.
How to choose the right wheel bearing
Before replacing, it is recommended that you familiarize yourself with the technical specifications, find out the inner and outer diameter of the bearing and the presence of an ABS sensor. Original kits are installed on factory cars (taking into account the year of manufacture):
- NISSAN40202-JG01A;
- SKF VKBA 6996:
- NTN SNR R16874;
- NISSAN 43202-JG21A.

Important! Manufacturers produce wheel bearings for the front and rear axles. It is better to replace it with products that have proven themselves in the market.
Replacing the front wheel bearing in the Nissan X-Trail
Before work, raise the body with a jack to provide access to the desired node, remove the wheel.
Step-by-step replacement of the front wheel bearing using the Nissan X-Trail T30 as an example:
- Turn the steering wheel, press the brake pedal, remove the lock pin. Loosen the hub nut.
- Two fixing bolts are screwed on the caliper from the bottom and top, and the top one is removed.
- Tie down the caliper so you don't damage the brake hose under your own weight.
- Take out the pads, at the same time checking their condition. If the resource is low, they also need to be replaced.
- Remove the brake mount.
- Loosen one top screw. It is located on the back of the disc.
- Then release and pull out the second one from the bottom.
- Remove the part and brake disc.
- Unscrew the ABC sensor, pull it out and set it aside.
- The steering is disassembled, mounted on a nut.
- Remove the rack nuts and drive in the bolts.
- Release the lower ball joint.
- Set the outer pad aside.
- Remove the steering knuckle.
- Pry with a screwdriver and remove the retaining ring.
- Using a hydraulic press, the cube is squeezed out
- The old bearing is removed in the same way.
- Using a special tool (collector), remove the remaining clip from the hub.
- Replace and click.
- Replace snap ring, steering knuckle with wheel bearing assembly.
- Putting everything together in reverse order.
Clue! If the car is being replaced for the first time, it is better to film a phased disassembly on video so as not to get confused when installing parts.
Do-it-yourself rear wheel bearing replacement in Nissan X-Trail
The rear axle has a drum brake system. Car maintenance in terms of disassembling components is much easier than in the front.
The replacement sequence for a Nissan X-Trail with a T31 body of a wheel bearing:
- We put the Nissan X-Trail on the jack, removed the wheel, took out the locking pin.
- The wheel is back in place. Fasten with two bolts, lower the jack and use a 30 head to break the hub nut.
- We unscrew the two bolts securing the caliper and bracket.
- Remove the drum with a wooden mallet.
- Release the mounting springs and remove the pads.
- Remove the ABC sensor.
- Let go of the pull.
- Remove the support.
- Disconnect the steering cable.
- While holding the assembly, unscrew the nut.
- The axle shaft is squeezed out by a press.
- Using a special tool, the old wheel bearing race is removed.
- Replace it with a new one, set the stops from the bottom and top and press the axle shaft into place.
- If the process is difficult, lubricate the surface with concentrated soapy water.
- Replace the hub nut after replacement.
- Everything is going in reverse order.
Conclusion
Replacing the front and rear wheel bearings on the Nissan X-Trail t30, t31, t32 is included in the terms of maintenance. A scheduled repair determines the mileage of the car, an unscheduled repair determines the condition of the tracks, excessive axle load and the poor quality of the material of the previous analogue. Replacing a defective hub part is a rather complicated process that requires certain skills and special equipment.
