Tools Required
J 8001 Dial Indicator Set,
or equivalent
- Raise and suitably 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 from the vehicle, except for full floating type
rear drive axles. Refer to
Front Brake Rotor Replacement
and
Rear Brake Rotor Replacement
in Disc Brakes.
- Remove any loose debris or corrosion from the hub/axle flange surface.
- Position the J 8001
, or equivalent, on the machined surface of the wheel hub/axle flange
(or brake rotor on full-floating axles) 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 13.
- 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:
