WHEEL BEARINGS—CHECK ADJUSTMENT
Tapered roller bearings are used on
CAUTIO N:
all series vehicles and they have a slightly loose
feel when properly adjusted. This differs from
ball bearings which may be pre-loaded without
adverse effect. A design feature of front wheel
taper roller bearings is that they must NEVER
be pre-loaded. Damage can result by the steady
thrust on roller ends which comes from pre-
loading.
1. Raise car and support at front lower control arm.
2. Spin wheel to check for unusual noise.
3. If bearings are noisy or excessively loose, they
should be cleaned and inspected prior to
adjustment.
NOTE: To check for loose bearings, grip the
tire at the top and bottom and move the
wheel assembly in and out on the spindle.
