Tools Required
J 8001 Dial Indicator
Set, or equivalent
- Raise and support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Mark the location of the wheels to the wheel studs and mark the
specific vehicle position on each tire and wheel - LF, LR, RF, RR.
- Remove the tire and wheel assemblies from the vehicle. Refer to
Tire and Wheel Removal and Installation
in Tires
and Wheels.
- Remove the brake rotors and/or brake drums from the vehicle. Clean
the mounting surfaces of the brake rotors, the brake drums, if equipped, and
the hub/axle flanges of any loose debris, rust, and corrosion. Refer to the
following procedures:
- Position the J 8001
, or equivalent, on the machined surface
of the wheel hub/axle flange outside of the wheel studs.
- Rotate the hub one complete revolution in order to find the low
spot.
- Set the J 8001
,
or equivalent, to zero at the low spot.
- Rotate the hub one more complete revolution and measure the total
amount of wheel hub/axle flange runout.
Specification - Guideline
Wheel hub/axle flange runout tolerance guideline: 0.132 mm (0.005 in)
- If the runout of the wheel hub/axle flange IS within specification,
proceed to step 12.
- If the runout of the wheel hub/axle flange is marginal, the wheel
hub may or may not be the source of the disturbance.
- If the runout of the wheel hub/axle flange is excessive, replace
the wheel hub/axle flange. Measure the runout of the new wheel hub/axle flange.
Refer to the appropriate procedure:
- Position the J 8001
, or equivalent, in order to contact the
wheel mounting studs.
Measure the stud runout as close to the
flange as possible.
- Turn the hub one complete revolution to register on each of the
wheel studs.
- Zero the J 8001
,
or equivalent, on the lowest stud.
- Rotate the hub one more complete revolution and measure the total
amount of wheel stud - stud circle - runout.
Specification - Guideline
Wheel stud runout tolerance guideline: 0.254 mm (0.010 in)
- If the runout of the wheel studs - stud circle - is
marginal, the wheel studs may or may not be contributing to the disturbance.
- If the runout of the wheel studs - stud circle - is
excessive, replace the wheel studs as necessary. Measure the runout of the
new wheel studs. Refer to the appropriate procedure:
