Removal
Disconnect the negative cable from the battery with the ignition off.
Note: This will erase the data from the electronic memory blocks. See the instructions in the chapter "Electrical equipment".
Loosen the central axle nut. The car must be on the ground, as it is tightened with a high torque. Bend back the safety tab beforehand.
Loosen the upper shock absorber strut mounting nut using a 1/9 mm deep socket wrench while holding the shock absorber rod with a 6 mm Allen key to prevent the rod from turning.
Mark the position of the front wheel relative to the hub so that the balanced wheel can be installed in the same position. Loosen the wheel nuts when the car is on the ground. Raise and support the car from the front, remove the front wheel.
Remove the brake hose holder.
Remove the brake caliper.
Hang the caliper on the bodywork with a wire, making sure that the brake hose is not twisted or stretched. The brake hose remains connected, otherwise the brakes will need to be bled after assembly.
Remove the tie rod end from the steering knuckle.
Caution: After removing the steering knuckle, wrap the tie rod end with a rag to avoid damaging it.
If there is one, unscrew the anti-lock brake system sensor.
Unscrew the axle nut and remove it together with the washer.
Remove the brake disc.
Remove the clamp bolt and nut (arrow) of the front axle joint. Pull the wishbone DOWN from the steering knuckle.
Caution: Make sure that the rubber boot of the ball joint is not damaged. Wrap the boot with a cloth to protect it.
Using a puller, pull the steering knuckle off the drive shaft.
Caution: Make sure that the drive shaft does not come loose from the inner CV joint.
Unscrew the shock absorber strut clamp bolt on the steering knuckle.
Spread the steering knuckle clamp with a suitable tool (1). To do this, insert the tool into the slot (clamp) of the steering knuckle and turn its lever by 90°.
Pull the steering knuckle down (2).
Installation
Place the steering knuckle on the shock absorber strut and align it. Remove the clamp spreader on the knuckle.
Insert the new shock absorber self-locking clamp bolt onto the steering knuckle, making sure the bolt goes through the slot in the mounting plate. Tighten the clamp bolt to 85 Nm.
Place the steering knuckle onto the drive shaft.
Tighten the new axle nut until it stops, but do not tighten it yet.
Press the ball joint of the transverse control arm from below until it stops in the steering knuckle (B). Insert the bolt (C) from the front, it enters the groove on the transverse control arm journal (D). (A - dust cover).
Caution: The bolt head must point in the direction of travel, i.e. forwards. Tighten the new self-locking nut of the bolt to a torque of 50 Nm.
If removed, screw in the anti-lock braking system sensor and tighten to 10 Nm.
Install the brake disc and secure it with a new clamp.
Install the brake caliper.
If the brake hose was disconnected, remove air from the brakes.
Insert the steering rod end into the steering knuckle and secure it with a new nut, tightening it to a torque of 35 Nm. At the same time, hold the journal with a hex key.
Install the front wheel according to the marks made earlier. Lightly lubricate the centering holes on the disk with consistent grease. Do not lubricate the threads of the wheel studs. Install the wheel. Lower the car and tighten the wheel nuts crosswise to a torque of 90 Nm.
Tighten the upper nut of the shock absorber strut to a torque of 50 Nm, holding the shock absorber rod with an Allen key.
Note: To ensure that the nut is tightened to the correct torque, a special open-end wrench must be used.
Tighten the axle nut to 270 Nm and bend the retainer tongue.
Note: The vehicle must be on the ground.
Check the freedom of movement of the brake hose and the anti-lock sensor wire. To do this, the assistant should turn the front wheels left and right until they stop.
Connect the negative cable to the battery, set the clock and enter the required codes.
