C 2500 Truck 2WD V8-5.7L VIN R (1997)
Wheel Bearing: Adjustments
Front Suspension and Axle
FRONT WHEEL BEARINGS ADJUSTMENT
CAUTION: Never preload the front wheel bearings. Damage can result by the steady pressure on the roller ends which comes from preloading.
NOTE:
-
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.
REMOVE
NOTE: Raise the vehicle and support it with suitable safety stands.
Remove or disconnect the following:
1. Wheel cover, if used.
2. Cap (10) from the hub.
3. Cotter pin (11). Tighten (12) to 16 Nm (12 ft. lbs.) while turning the wheel forward by hand. This will seat the bearings.
4. Adjust the nut (12) to a "just loose" position by hand, then back the nut (12) off until the hole in the spindle aligns with a slot in the nut. DO NOT
BACK THE NUT (12) OFF MORE THAN 1/4 TURN.
INSTALLATION
CAUTION: 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.
Install or connect the following:
1. New cotter pin (11).
-
Be sure the cotter pin (11) ends do not interfere with the cap (10). Bend the ends of the cotter pin (11) against the nut (12) and cut off any extra
pin length.
