Disassembly
Steering knuckle internals
1 - hub;
2 - brake shield;
3 - rotary disk;
4 - bearing;
5 - retaining ring.
Remove the inner seal.
Using the tool, remove the hub.
Turn away two bolts and remove a brake board.
Remove the circlip securing the bearing outer ring from the steering knuckle.
Remove the hub bearing. For gripping the outer part of the inner cage (1) using a puller, it is necessary to break in two places (arrows) outer gland (2), as it shown on the picture.
Using a puller, remove the inner race of the bearing from the hub.
After installing the outer part of the inner race removed from the hub into the bearing, use a puller to remove the bearing.
Remove the outer seal.
Check the contact surfaces of the front hub and brake disc for wear and damage.
Assembly
Assembly is carried out in the reverse order, taking into account the following:
Install the hub bearing. Fill the bearing with grease.
Apply a light coat of grease to the mating surfaces of the steering knuckle and hub. Using the tool, press the bearing into the steering knuckle.
Attention: The pressing force is applied to the outer race of the bearing.
After installing the circlip, install the outer oil seal. Using a mandrel, install the seal (from the side of the hub) into the knuckle flush with the end surface of the steering knuckle Apply grease to the seal lip and the inner and end surfaces of the oil seal in contact with the hub.
Install the brake shield.
Install the hub. Using the indicator, measure the value of the axial clearance of the hub bearing, for which first secure the steering knuckle in a vice. The maximum allowable value is 0.05 mm. If, when tightening the nut to a torque of 216-255 Nm, the starting torque and the axial clearance of the hub bearing do not lie within the specified limits, it is necessary to replace the bearing and assemble the assembly again. Tighten the nut to a torque of 216-255 Nm.
Apply grease to the back of the inner seal. Install the inner seal (1) into the pivot (2) until it comes into contact with the retaining ring.
