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 hub/axle flanges 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. 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 outside of the wheel bolt holes.
- 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 lateral runout.
Specification (Guideline)
Wheel hub/axle flange runout tolerance guideline: 0.05 mm (0.002 in)
- Position the J 8001
, or equivalent, on the circumference surface of the wheel hub/axle
flange.
- 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 radial runout.
Specification (Guideline)
Wheel hub/axle flange runout tolerance guideline: 0.05 mm (0.002 in)
- If the runout of the wheel hub/axle flange IS within specification,
proceed to step 17.
- 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:
- Inspect the threads and the tapered seat portion on each of the
wheel bolts for damage.
- Wheel bolts exhibiting damaged threads and/or damaged tapered
seats require replacement.
- Place the threaded portion of each wheel bolt along a straight
edge to inspect for straightness.
- Wheel bolts that are not straight require replacement.
