Note: Two different wheel bearing housings were installed as standard, they differ in the thickness of the steering pendulum arm. When replacing the wheel bearing housing, ensure that the thread length on the tie rod end is sufficient (it is necessary to ensure a sufficient number of free threads) If there is not enough free threads, it is necessary to install a new tie rod end with a longer thread, compliance.
Loosen the bolts securing the drive shaft to the wheel hub. Remove the support arm. Remove the brake line and electrical wire bracket from the wheel hub bearing housing. Remove the front speed sensor. Remove the brake caliper and secure it to the body so that its weight does not press on the brake hose/brake line and does not damage it/it. Remove the brake disc. Loosen the bolts "arrows" and remove the brake protective shield "1".
Loosen the nut of the guide arm hinge pin so that it is flush with the thread of the hinge pin. If necessary, hold it from turning while loosening. To protect the thread, leave the nut on the pin screwed on a few turns. Press out the guide arm hinge pin from the conical socket using the T40010 A ball joint puller.
Disconnect bolt connection "1". Remove both upper suspension arm joint pins "2" from the hub bearing housing. Flaring of the splines in the hub bearing housing using a chisel, etc. is not allowed! Remove the hub bearing housing from the drive shaft splines and remove the hub bearing housing. The drive shaft must not hang freely, since bending will damage the inner joint. Suspend the drive shaft on a wire, attaching it to the body.
Installation
Installation in reverse order. In this case, it is necessary to take into account the tightening torques. Slide the hub bearing housing onto the splines of the drive shaft. Insert both pins of the upper arms "2" into the hub bearing housing and insert bolt "1".
I
Remove any adhesive residue from the threads of the ball joint pins and the guide arm. Secure the guide arm to the wheel bearing housing and tighten the threaded connection. Install the transverse arm. When tightening, press the upper arm as far down as possible! Tighten bolt connection "1". Install the brake disc and caliper. Tighten the drive shaft mounting bolts to the wheel hub. For vehicles with automatic headlight range control, perform the basic setting of the headlights. After removing and installing the vehicle level sensor or loosening the rods on vehicles with electronic damping control, the standard suspension position must be readjusted. After re-adapting the adjustment position on vehicles with lane assist, the lane assist control unit "J759" must be recalibrated. Tighten the wheel. The wheel alignment angles must be adjusted.
