Front Suspension
FRONT WHEEL BEARINGS ADJUSTMENT
ADJUSTMENT PROCEDURE
NOTICE: Never preload the front wheel bearings. Damage can result by the steady load on the roller ends that comes from preloading.
Important:
^
Adjust the front wheel bearings correctly in order to ensure the front suspension functions properly.
^
The bearings must be a slip fit on the spindle.
^
Lubricate the bearings in order to ensure that the roller bearings will roll and not skid.
^
The spindle nut must have a free-running fit on the spindle threads.
1. Raise the vehicle. Support the vehicle with safety stands.
2. Remove the wheel cover, if used.
3. Remove the dust cap from the hub.
4. Remove the cotter pin.
Tighten
Tighten the hub/rotor bearing nut to 16 Nm (12 ft. lbs.), while turning the wheel forward by hand. This will seat the bearings.
NOTICE: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that
application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the
fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or
other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint
clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these
instructions can help you avoid damage to parts and systems.
Important: Do not back the nut off more than 1/4 turn.
5. Adjust the nut to so that it is just loose. Then, back the nut off until the hole in the spindle aligns with a slot in the nut.
6. Install a new cotter pin.
6.1. Make sure the cotter pin ends do not interfere with the cap.
6.2. Bend the ends of the cotter pin against the nut.
6.3. Cut off any extra pin length.
