Front Wheel Bearing and Hub

Steering Knuckle Removal and Installation

REMOVAL

CAUTION: Before removing the front axle assembly, remove the wheel sensor from the assembly. Then move it away from the front axle assembly area. Failure to do so may result in damage to the sensor wires and the wheel sensor becoming inoperative.

1. Remove wheel bearing lock nut using power tool.





2. Remove brake caliper assembly and rotor using power tool. Brake hose need not be disconnected from brake caliper. In this case, suspend caliper assembly with wire so as not to stretch brake hose. Be careful not to depress brake pedal, or piston will pop out. Make sure brake hose is not twisted.





3. Separate tie rod from knuckle with Tool. Install stud nut on stud bolt to prevent damage to stud bolt.





4. Separate drive shaft from knuckle by lightly tapping it. If it is hard to remove, use a puller. Cover boots with shop towel so as not to damage them when removing drive shaft.





5. Remove lower strut mounting bolts.





6. Loosen lower ball joint tightening nut.
7. Separate knuckle from lower ball joint stud with Tool.
8. Remove knuckle from transverse link.

INSPECTION AFTER REMOVAL
Wheel Hub
^ Check wheel hub for cracks by a magnetic exploration or dying test, and replace if cracked.

Knuckle
^ Check for deformity, cracks (by magnetic exploration or dying test) and damage on steering knuckle, replace if necessary.

Snap Ring
^ Check for wear and damage on snap ring, replace if necessary.

INSTALLATION
^ To install, reverse the removal procedure.

Disassembly and Assembly

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.
^ When replacing wheel bearing, replace complete wheel bearing assembly (inner races and outer rail).





1. Press out wheel hub from knuckle with a suitable tool.





2. Remove snap rings.





3. Press out wheel bearing from knuckle.

ASSEMBLY





1. Install inner snap ring into groove of knuckle.
2. Press new wheel bearing assembly into knuckle until it contacts snap ring.

CAUTION:
^ Do not press inner race of wheel bearing assembly.
^ Do not apply oil or grease to mating surfaces of wheel bearing outer race and knuckle.

3. Install outer snap ring into groove of knuckle.





4. Press wheel hub into knuckle.
Maximum load P :50 kN (5.1 ton, 5.6 US ton, 5.02 Imp. ton)
5. Check bearing operation.





a. Add load P with press.
Load P : 35 - 50 kN (3.6 - 5.1 ton, 3.9 - 5.6 US ton, 3.51 - 5.02 Imp ton)





b. Spin knuckle several turns in both directions.
c. Make sure that wheel bearings operate smoothly.
