There are different types of king pin bushings depending on the configuration of your vehicle.
•
Bronze bushings in the axle beam.
•
Bronze bushings in the steering knuckle.
•
Metal backed teflon bushings in the axle beam.
NOTE: Bronze bushings must be reamed or broached to the proper
diameter after they are pressed into the axle beam or steering
knuckle.
1. Make sure the key-switch is in the “OFF” position, then remove
the key.
2. Place the forward-reverse switch in the center “OFF” position.
3. Set the park brake.
4. Place blocks under the rear wheels to prevent vehicle movement.
5. Disconnect the main positive and negative cables at the batteries.
Always use a lifting strap, hoist, and jack stands, of adequate capacity
to lift and support the vehicle. Failure to use lifting and support devices
of rated load capacity may result in severe bodily injury.
Failure to correctly broach or ream bronze bushings may result in
steering difficulty and loss of control of the vehicle causing severe
bodily injury and /or property damage.
Refer to the illustration below for the type of bushing in your vehicle.
