Hub, Rotor and Wheel Bearing

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

REMOVAL
1. Remove wheel bearing lock nut.





2. Remove brake caliper assembly and rotor. Brake hose need not be disconnected from brake caliper.

CAUTION:
^ Suspend brake caliper with wire so as not to stretch brake hose.
^ Be careful not to depress brake pedal, or caliper piston will pop out.
^ Make sure brake hose is not twisted.





3. Separate tie rod from steering knuckle with ball joint remover tool No. HT7252000, or equivalent.

CAUTION: Install stud nut on stud bolt to prevent damage to stud bolt.





4. Separate drive shaft from steering knuckle by lightly tapping it. If it is hard to remove, use a puller.

CAUTION: When removing drive shaft, cover boots with a shop towel to prevent damage to them.





5. Remove strut lower mounting bolts.
6. Loosen lower ball joint tightening nut.
7. Separate steering knuckle from lower ball joint stud with ball joint remover tool.
8. Remove steering knuckle from transverse link.

DISASSEMBLY

CAUTION:
^ When removing wheel hub or wheel bearing from steering knuckle, replace wheel bearing assembly (outer race, inner race and grease seals) with a new one.
^ Wheel bearing does not require maintenance. If any of the following symptoms are noted, replace wheel bearing assembly.
^ Growling noise is emitted from wheel bearing during operation
^ Wheel bearing drags or turns roughly. This occurs when turning hub by hand after bearing lock nut is tightened to specified torque.





Wheel Hub
^ Drive out wheel hub with inner race from steering knuckle with a suitable tool





Wheel Bearing
1. Remove bearing inner race, then remove outer grease seal.





2. Remove inner grease seal from steering knuckle.





3. Remove snap ring.





4. Press out bearing outer race.

NOTE: When replacing wheel bearing, replace wheel bearing assembly (including inner and outer races).

INSPECTION

Wheel Hub And steering knuckle
^ Check wheel hub and steering knuckle for cracks by using a magnetic exploration or dyeing test.

Snap Ring
^ Check snap ring for wear or cracks. Replace if necessary.





ASSEMBLY
1. Press new wheel bearing assembly into steering knuckle. Maximum load P: 29 kN (3 ton, 3.3 US ton)

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

2. Install snap ring into groove of steering knuckle.





3. Pack grease seal lip with multi-purpose grease.





4. Install outer grease seal. Maximum load P.: 10 kN (1 ton, 1.1 US ton)





5. Install inner grease seal. Maximum load P: 10 kN (1 ton, 1.1 US ton)





6. Press wheel hub into steering knuckle. Maximum load P: 29 kN (3 ton, 3.3 US ton)

CAUTION: Be careful not to damage grease seal.

7. Check bearing operation.





a. Add load P with press. Load P: 34.3 - 49.0 kN (3.5 - 5.0 ton, 3.9 - 5.5 US ton)





b. Spin steering knuckle several turns in both directions.
c. Make sure that wheel bearing operates smoothly.

INSTALLATION
1. Install steering knuckle with wheel hub.
2. Replace strut lower mounting nuts.





3. When installing steering knuckle to strut, apply oil to threaded portion of drive shaft and both sides of plain washer. Also, be sure to hold bolts while tightening nuts. Torque to 114 - 133 Nm (84 - 98 ft. lbs.).
4. Tighten wheel bearing lock nut to 196 - 275 Nm (145 - 202 ft. lbs.).
5. Check wheel bearing axial end play. Axial end play: 0.05 mm (0.0020 inch) or less.
