Adjustment Procedure
Tools Required
- Check the king pin bearing
or steering knuckle preload torque. Use the J 35999
and a piece of string.
- Place the string (2) on the steering knuckle (1) at the point
where the threads meet the spindle.
- Pull the knuckle from lock position to lock position. Note the
scale reading, ignoring the force needed to start the rotation.
Reading
The correct reading on the J 35999
should be 30-60 N·m (22-44 lb ft).
If the reading is outside of these limits, change the shim thickness.
- In order to change the
shim, the king pin nut must be removed. Use the J 39758
to remove the nut.
- Change the thickness of the shim (4).
• | In order to increase the torque, reduce the shim thickness. |
• | In order to decrease the torque, increase the shim thickness. |
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Check the king pin
nut (2) for correct torque specification.
Tighten
Tighten the king pin nut (2) to 550 N·m (406 lb ft).
