- Remove wheel bearing lock nut.





- Remove brake caliper assembly and rotor.

Note: Brake hose need not be disconnected from brake caliper. Be careful not to depress brake pedal, or piston will pop out. Make sure brake hose is not twisted.





- Separate tie-rod from knuckle with Tool.

Note: Install stud nut inverted on stud bolt to prevent damage to stud bolt.





- Remove kingpin cap and securing nut. Separate kingpin from knuckle.





- Separate drive shaft from knuckle with drift.

Note: When removing drive shaft, cover boots with waste cloth to prevent damage to them.





- Remove ball joint securing nut. Separate from knuckle using tool (as for tie-rod).





Installation

- Install knuckle with wheel hub.

- Tighten wheel bearing lock nut.
235 - 314 Nm
(24 - 32 kg-m, 174 - 231 ft-lb)

- Check that wheel bearings operate smoothly.





- Check wheel bearing axial end play.

Axial end play:
0.05 mm (0.0020 in) or less.

Disassembly

CAUTION: When removing wheel hub or wheel bearing from knuckle, replace wheel bearing assembly (outer race, inner races and grease seals) with a new one.

WHEEL HUB





- Drive out hub with inner race (outside) from knuckle with a suitable tool.

WHEEL BEARING
