Wheel Hub: Service and Repair
Front Rotor Assemblies.:
The front wheels are attached to the front hub and rotor assemblies. The front hub and rotor assemblies are supported by one-piece roller bearings mounted in the steering knuckle. The wheel bearing is pressed into the steering knuckle. The hub assembly is pressed into the wheel bearing during assembly.
For easier service, the rotor unbolts from the hub, and the steering knuckle can be easily removed from the strut.
REMOVAL
Removing Staking Nut.:
1. Remove the wheel.
2. Carefully raise the staked portion of the halfshaft attaching nut using a small cape chisel.
Exploded View Of Stabilizer Bar.:
3. Remove halfshaft attaching nut. Discard the nut. It must not be reused.
NOTE: When loosening the nut, lock the hub by applying the brakes.
4. Remove the stabilizer bar to control arm attaching bolt, nut washers and bushings.
Separating Tie Rod.:
5. Remove the cotter pin and the tie rod end attaching nut.
6. Separate the tie rod end from the steering knuckle arm using Tie Rod End Separator TS5M-3395-A. If the tie rod end does not separate easily, give the steering knuckle a sharp blow with a soft faced hammer to shock the taper.
7. Remove the caliper and anchor bracket assembly. Hang the caliper on a hook so it does not hang from the brake hose.
8. Remove the rotor.
Remove Ball Joint Clamp Bolt And Nut.:
9. Remove the lower control arm ball joint clamp bolt and nut.
Separating Ball Joint.:
10. Pry downward on the lower control arm to separate the ball joint from the steering knuckle.
Removing Steering Knuckle.:
11. Remove the steering knuckle to strut attaching bolts.
12. Slide the front hub/steering knuckle assembly out of its bracket in the strut and off the end of the halfshaft. Use care to prevent damage to the grease seals.
Removing Hub.:
NOTE: If the wheel hub binds on the halfshaft splines, it can be loosened by lightly tapping with a plastic faced hammer on the end of the halfshaft.
CAUTION: Never use any type of metal faced hammer to separate the halfshaft from the wheel hub. Damage to the CV joint - internal components will result. If the halfshaft splines become rusted to the hub, a two-jaw puller such as D8OL-1002-L or hub puller must be used to separate them.
INSTALLATION
Removing Hub.:
1. Position the front hub/steering knuckle assembly over the halfshaft and into the strut.
Reinstall Lower Ball Joint.:
2. Install the steering knuckle to strut attaching bolts and nuts.
^ Tighten the attaching nuts to 93-117 Nm (69-86 ft lb).
3. Position the lower control arm ball joint through the steering knuckle and install the clamp bolt and nut.
^ Tighten the clamp bolt to 43-54 Nm (32-40 ft lb).
4. Install brake rotor.
5. Install caliper and anchor bracket.
Fig. 5 Staking Halfshaft Attaching Nut:
6. Install a new halfshaft attaching nut.
^ Tighten the attaching nut to 157-235 Nm (116-174 ft lb).
7. Stake the halfshaft attaching nut using a cold chisel with the cutting edge rounded.
CAUTION: If the nut splits or cracks after staking, it must be replaced with a new nut.
8. Connect the tie rod to the steering knuckle arm and install the attaching nut.
Tighten the attaching nut to 29-44 Nm (22-33 ft lb) and install a new cotter pin.
NOTE: If the slots in the nut do not align with the cotter pin hole in the ball joint stud, tighten the nut for proper alignment. Never loosen the nut.
Checking Clearance On Stabilizer Bolt.:
9. Position the stabilizer bar and install the stabilizer link assembly including the attaching bolt, nut, washers, sleeve and rubber bushings.
^ Tighten the attaching nut until 2O mm (0.79 inch) of the bolt threads extend beyond the nut.
10. Install the wheel.
11. Torque lug nuts to 88-118 Nm (65-87 ft lb).
