Front wheel hub and steering knuckle. 1. Steering knuckle; 2. Dirt shield; 3. Wheel hub and wheel bearing assembly; 4. Cotter pin.
Removal
Wheel hub and wheel bearing assembly.
1. Remove the wheels from the vehicle.
2. Remove the wheel sensor from the steering knuckle. See chapter «Brake system».
Attention. Do not pull on the wheel sensor wiring.
3. Remove the locking plate from the stand. See chapter «Brake system».
4. Remove the mounting bolts from the caliper bracket. Hang the caliper bracket so that it does not interfere with your work. See chapter «Brake system».
Attention. Do not press the brake pedal after removing the brake caliper.
5. Remove the brake disc.
Attention:
- Before removing the brake rotor, make alignment marks on the brake rotor and on the wheel hub and wheel bearing assembly.
- Don't drop the brake disc.
6. Remove the cotter pin, then loosen the hub locknut.
7. Separate the wheel hub and wheel bearing assembly from the drive shaft by lightly tapping the end with a hammer and a wooden block, then unscrew the hub locknut.
Attention:
- Do not bend the drive shaft joint to a large angle. Also, do not overextend the sliding joint.
- Do not allow the drive shaft to hang unsupported by the housing (or hinge assembly), shaft and other components.
Note. If after performing this procedure you cannot separate the wheel hub and wheel bearing assembly from the drive shaft, use a suitable puller.
8. Remove the wheel hub and wheel bearing assembly.
Steering knuckle
1. Remove the wheel hub and wheel bearing assembly, then the mud shield.
2. Separate the wishbone from the steering knuckle.
3. Remove the steering knuckle from the strut assembly.
4. Loosen the outer tie rod end nut.
5. Using a ball joint remover, remove the outer tie rod end (1) from the steering knuckle (2) so as not to damage the ball joint cover (3).
Attention. To avoid damaging the threads and causing the ball joint remover to come off, tighten the nut by hand.
6. Remove the steering knuckle from the vehicle.
Installation
Installation is carried out in the reverse order of removal, taking into account the following:
Attention:
- If you are reusing the brake disc, align the marks made during removal.
- Perform final tightening of all components removed, including the wheel hub and wheel bearing assembly and steering knuckle, with the vehicle unloaded.
Check after removal
Check the components for deformation, cracks or other damage. Replace if necessary.
Checking the ball joint
Check whether the covers of the transverse arms and ball joints of the outer tie rod ends are broken, whether there is any play in the axial direction, and also check the tightening torque. See below and chapter «Steering».
Check after installation
- Check the alignment of the front wheels. See below.
- After checking the front wheel alignment, adjust the neutral position of the steering angle sensor. See chapter «Brake system».
