trails around the nuts. Ensure that
no cracks or damage are present at
wheel mount holes.
Check for leaks on outboard or
inboard sides of wheel. Verify that
the oil level in the hub is correct.
Wheel and Tire Balancing
Out-of-round or out-of-balance
wheels or tires can cause vehicle
vibration, bounce, and shimmy.
Replace damaged or out-of-round
wheels. Out-of-round tires and
wheel assemblies can sometimes
be corrected by rechecking the tire
relative to the wheel. The tire and
wheel assembly should thereafter
be dynamically balanced and
reinspected while spinning for an
out of round condition.
Hub-Piloted Wheel Installation
Procedure
Warning
To prevent property damage,
personal injury, and/or death, use
only the same type and style
wheels and mounting hardware to
replace original parts. Failure to
do so may result in an assembly
that looks fine but does not fit
together properly. This could
cause wheel or fastener failures.
Out-of-round tires and wheel
assemblies can sometimes be
corrected by re-clocking the tire
relative to the wheel.
Tightening procedure for disc
wheels with flange nuts
(hub-piloted):
1. Clean the mating surfaces of
the hub, drum, and wheel(s) as
well as the wheel studs and
wheel nuts with a wire brush
prior to assembly.
Vehicle Care
2. Lubricate the two-piece wheel
nuts by putting two drops of oil
in the slot between the nut and
washer and spin the washer to
spread the oil around the
nut-to-washer contact surface.
3. Carefully lubricate the wheel
stud threads by wiping them
with a freshly oiled cloth. Do
not get the oil on any other
surfaces or the wheel clamping
effectiveness will be reduced.
4. To prevent aluminum wheels
from getting stuck on the hub
due to corrosion, apply a thin
coat of anti-seize compound or
disc brake corrosion control
grease to the hub pilot
pads only.
5. Slide the inner and outer
wheels (if duals) or the steer
wheel over the wheel studs
and onto the pilot pads of the
hub. Care must be taken to
avoid damage to the stud
threads while positioning the
wheel. Ensure that the wheel is
resting on the pilot pads and is
against the brake drum.
