STEERING KNUCKLES - CONTINUED
BUSHING INSPECTION - CONTINUED
Check the tightness of the steering connections
such as cross tube arms, steering arm, etc. For
units with sealed knuckle pins, check knuckle pin
seal for rips, tears and excessive wear. Do not
remove the seals from the steering knuckle
unless replacement is necessary or the knuckle
is to be rebushed.
Remove the thrust bearing seal from the thrust
bearing case and inspect the seal for wear, rips
and tears. On aluminum axles with integral
seals, do not remove seal.
Check thrust bearing.
Check knuckle pin bushings for wear, flaking or
scoring. Compare diameter with correct wear
limit. If the bushing diameter is .010" greater
than the new bushing dimension, replace the
Check axle center bore for condition and size.
Replace center if bore is 0.001" greater than
Any indication of looseness in the total steering linkage arrangement
under normal steering loads is sufficient cause to immediately check
all pivot points for wear, regardless of accumulated mileage.
Steering linkage pivot points should be checked each time the axle
assembly is lubricated.
