Examination
1. Apply the parking brake, jack up the front of the vehicle and place it on jack stands. Manually rotate the wheel, listening for the sounds made by the wheel bearing. Grab the wheel with your hands and rock it for signs of play in the bearing - try not to confuse play in the bearings with play in the joints of the suspension and steering components (see chapter Current service).
Replacement
1. Apply the parking brake, jack up the front of the vehicle and place it on jack stands. Remove the corresponding front wheel.
2. Remove the brake caliper and, without disconnecting the flexible hydraulic hose, tie it aside to the suspension elements, - release the hose from the support bracket and remove it, after releasing the clamp, - remove the brake disc (see chapter Brake system).
3. Remove the protective cap of the hub nut, block the hub from turning by holding it with a pry bar tucked between the two temporarily screwed wheel bolts, remove the cotter pin and give the nut.
The nut is very tight.
4. Take cotter pin and give a nut of fastening of a steering tip. Using a puller, press the ball pin of the tip out of the lever on the steering knuckle. Give a fixing nut and disconnect a vertical draft of the stabilizer from a rack of a suspension bracket.
5. Turn out a bolt of a collar of fastening of a finger of a spherical support to a fist, - try to remember an adjusting position of a bolt.
The compilers of this Guide recommend replacing the bolt and nut without fail.
7. Use a chisel or large screwdriver to spread the clamp at the bottom of the knuckle.
8. While pressing the lower suspension arm, release the ball joint pin from the clamp. Take the rack to the side and release the lever - try not to damage the boot of the ball joint.
9. On ABS-equipped models Disconnect the wiring from the wheel sensor.
10. Move the fist outward, pushing the drive shaft trunnion out of the hub - if necessary, knock out the shaft with a hammer through a brass drift.
11. Mark the relative position of the bearing outer race, knuckle and base plate.
12. From the back side of the fist, unscrew the three bolts of the bearing assembly, - during assembly, the bolts must be replaced without fail.
13. Remove from fist (4) bearing assembly and base plate (3), - take care not to damage the wiring of the wheel sensor.
14. The bearing assembly is built into the hub assembly and its dismantling is not possible. In case of failure of any of the elements of the hub, the entire assembly must be replaced.
15. Having cleaned the mating surfaces, press the base plate against the fist - make sure that the landing marks applied during the dismantling of the components are aligned correctly. Lightly lubricate the threaded part of the new mounting bolts with an anaerobic fixative sealant, then screw in the latter and tighten them in several stages to the required torque (see Specifications).
16. Pull the fist out and insert the drive shaft trunnion into the hub. Install the washer, then screw on the nut and tighten it slightly until the shaft stub is fully seated in the hub. The final tightening of the nut is done later (see below).
17. On ABS-equipped models connect the wiring harness to the wheel sensor, push the lower arm down and insert the ball joint pin into the knuckle clamp.
18. Remove the expanding wedge from the clamp lock and fill in a new bolt. Tighten the nut to the required torque.
19. Place the tie rod end in the fist and tighten the nut of its fastening with the required force. If necessary, secure the nut with a new cotter pin. Connect the vertical link of the anti-roll bar to the suspension strut and tighten the fastening nut to the required torque.
20. Having blocked the hub from turning with a pry bar, tighten its hub nut in several stages with the required force (see Specifications). Install a new cotter pin and bend its outer leg around the nut. Bend the inner leg of the cotter pin inward, then bite off the free end.
21. Install the protective cap of the hub nut.
22. Reinstall the brake components (see chapter Brake system).
23. Install the front wheel, lower the vehicle to the ground and tighten the wheel bolts to specification.
