4. Now apply grease to the bottom bushing fitting. Keep
greasing until you see clean grease being purged and
the thrust bearing is full of grease.

Grease Until Clean Grease is Purged
Important Note: Rotating the knuckle assembly during the
greasing process may help to complete the purge. Do not
raise the vehicle during this process.
Steer Axle Grease Procedure
Kingpin Joint Greasing Procedure
1. With the vehicle on a level surface, block the front
and the back of at least one of the drive axle wheels
to keep the vehicle from moving. Set the parking brake.
Important Note: Do not raise the vehicles off the ground
during greasing. If the wheels are off the ground grease
will not pass through the thrust bearing properly. This may
cause premature bearing wear and/or failure.
2. Clean all grease fittings before you apply new grease.
3. Start by greasing the top bushing grease fitting. Grease
must be applied until new (clean) grease comes from
between the shim pack and the steer knuckle and/or beam.

Contaminated Grease – Continue Greasing
Important Note: The greasing of steer axle components is
not just to lubricate internal components. More importantly
it is to flush contamination that may have worked its way past
the seals. Greasing must continue until clean grease is purged.
