Removing the wheel trunnion with the hub
Attention. Performing the following procedure without first removing the front wheel ABS sensor may result in an accidental open circuit in the wiring harness. Before performing the following procedures, disconnect the front ABS wheel sensor harness (from the side of the drive shaft) and fix the wiring in a suitable place where it will not be erroneously touched when servicing the vehicle.
1. Working from the left side of the vehicle, disconnect the auto level sensor linkage.
2. Versions with all-wheel drive (4WD):
Loosen the drive shaft lock nut.
Install the replacement nut onto the threads of the drive shaft so that the lip of the nut is flush with the end of the drive shaft.
- Tap the nut with a copper mallet to dislodge the drive shaft from the front wheel hub.
- Detach drive shaft from wheel hub.
3. Remove the ABS wheel sensor.
4. Remove the brake hose clamp.
5. Remove the brake caliper assembly (see chapter "Brake system") and put aside, hanging it on the body with wire.
6. Remove the brake disc (see chapter "Brake system").
7. Unscrew the bolts securing the wheel hub to the trunnion and remove the wheel hub with dust cover.
8. Unscrew the lower nut of the anti-roll bar strut and disconnect the strut from the lower suspension arm.
9. Support the lower arm of the rear suspension with a jack.
10. To turn away an external bolt of the lower arm of a back suspension bracket.
11. Remove the rear suspension coil spring (see chapter "Suspension").
12. Unscrew the bottom bolt of the rear shock absorber.
13. Unscrew the outer bolt of the rear suspension transverse link.
14. To turn away a bolt of fastening of the trailing arm of a back suspension bracket.
15. To turn away an external bolt of the top lever of a back suspension bracket and to remove a pin.
16. If necessary, use a press to remove the bolts from the wheel hub.
Note: Wheel hub bolts should only be removed for replacement.
17. If necessary, remove the bushings from the trunnion:
Mark the pin as shown in the picture.
Using a special tool, press the bushing out of the pin.
Pressing out the front trunnion bushing
Pressing the rear bushing out of the trunnion
Installing the wheel axle with hub
Installation is carried out in the reverse order of removal, taking into account the following:
Installing bushings in the trunnion
Align the protrusions of the trunnion bush with the marks made during removal.
Install a new bushing into the trunnion using a press.
Pressing in front trunnion bushing
Pressing in the rear hub bush
Installing wheel hub bolts
Using a press, install new wheel hub bolts.
Installing the wheel hub bolts
Attention. The wheel hub bolts are tightened to a certain angle, but there is no yield strength tightening (as, for example, in the case of cylinder head bolts). Therefore, it is not necessary to check the length of the bolts.
Tightening the lock nut of the drive shaft (versions with all-wheel drive 4WD)
After tightening the lock nut to a torque of 390 Nm, unscrew it by 180 degrees, then tighten it again to a torque of 236-274 Nm.
Note: After installation, check and, if necessary, adjust the wheel alignment.
