Front Suspension and Axle
FRONT WHEEL BEARINGS ADJUSTMENT
Important: The continuous smooth functioning of the front suspension cannot be maintained unless the front wheel bearings are correctly adjusted. The
bearings must be a slip fit on the spindle and the wheel bearing must be lubricated to ensure that the roller bearings will roll and not skid. The spindle nut
must have a free-running fit on the spindle threads.
NOTICE: Never preload the front wheel bearings. Damage can result by the steady pressure on the roller ends which comes from preloading.
Remove or Disconnect
1. Raise the vehicle and support it with suitable safety stands.
2. The wheel cover, if equipped.
-
Tighten the hub and rotor bearing nut to 16 Nm (12 ft. lbs.) while turning the wheel forward by hand. This will seat the bearings.
Adjust
-
Nut to a "just loose" position by hand, then back the nut off until the hole in the spindle aligns with a slot in the nut. DO NOT BACK THE NUT
OFF MORE THAN 1/4 TURN.
Install or Connect
1. The new cotter pin.
-
Be sure the cotter pin ends do not interfere with the cap. Bend the ends of the cotter pin against the nut and cut off any extra pin length.
Measure
-
The end play in the hub/rotor assembly. Correct end play should measure 0.03 to 0.20 mm (0.001 to 0.008 inch).
2. The cap to the hub and rotor.
3. The wheel cover, if used.
4. Remove the safety stands.
5. Lower the vehicle.
