Wheel Bearing Housing

Wheel Bearing Housing

• Two different wheel bearing housings were installed in production; the difference between the two is the steering arm strength. Refer to the Electronic Parts Catalog (ETKA).

• When exchanging the wheel bearing housing, make sure the length of the thread on the tie rod end is sufficient (there must be approximately 5 mm extra thread). If this is not the case, then install a new tie rod end with a longer thread pin. Refer to the Electronic Parts Catalog (ETKA).

• Distinguishing characteristic, refer to => [ Wheel Bearing Housing with Different Steering Arm Thickness ] Removal and Replacement.

- Remove the bolt - 1 -.






- Remove booth joint pins in the upper control arm - 2 - from the wheel bearing housing.

The slits in the wheel bearing housing must not be widened using a chisel or similar tool!

- Loosen the wheel bearing housing from the drive axle splines and remove it.

• The drive axle must not hang down, otherwise the inner joint will be damaged by overflexing.

• Secure drive axle to body using wire.

Installing

Install in reverse order of removal. Note the following:

Tightening specifications, refer to=> [ Wheel Bearing Housing and Wheel Bearing Unit Overview ] Removal and Replacement.

- Insert both of upper control arm joint pins - 2 - in the wheel bearing housing and insert the bolt - 1 -.






- Remove the adhesive residue on the ball joint and guide link stub threads.

- Install the guide link on the wheel bearing housing and tighten.

- Install the control arm. Refer to => [ Track Control Arm ] Track Control Arm.

- Attach the tie rod end to the wheel bearing housing. Refer to => [ Tie Rods ] Tie Rods.

• Push the upper control arms down as far as possible while tightening the bolts!






- Tighten the threaded connection - 1 -.

- Install the brake disc and caliper.

- Tighten the drive axle to wheel hub threaded connection. Refer to => [ Threaded Connection Between Drive Axle and Wheel Hub, Loosening and Tightening ] Description and Operation.

- On vehicles with automatic headlamp range control system, perform a basic setting on the headlamps.

- If the vehicle level sensor was removed and installed on a vehicle with electronically controlled damping or if the linkage was loosened, the control position must be reprogrammed. Refer to => [ Control Position, Programming using Vehicle Diagnostic Tester ] Testing and Inspection.

- If the control position was reprogrammed on vehicles with lane assist, the directional stabilization assistance control module (J759) must be recalibrated. Refer to => [ Lane Assist Calibration Procedure ] Lane Assist Calibration Procedure.

- Tighten wheel.
