multipurpose lithium grease to provide initial lubrication.

is clean and dry.
2. Position and support the steering knuckle
assembly on the axle center.
3. Slide the thrust bearing between the lower face
of axle center and lower steering knuckle yoke,
Fig. 13. Thrust bearings that are not marked
"top" to indicate proper installation position must
be positioned with retainer lip down.
NOTE: If a reamer is used, it should be equipped

remaining one, or be long enough to ream both
bushings at the same time, Fig. 12.
4. Align the steering knuckle yoke holes with axle
center and thrust bearing holes.

knuckle yoke and raise knuckle so that all
clearance is taken up between lower yoke, thrust
bearing and lower face of axle center end.
6. Check the clearance between the top face of
upper axle center end and lower face of upper
knuckle pin boss. The clearance must not
exceed .015". Washers and shims are available
in various thickness to take up this clearance
and hold it within the desired .015" tolerance,
