Hub/Axle Flange and Wheel Stud Runout
Inspection
Special tool
J 8001 Dial Indicator Set, or equivalent
1. Raise and support the vehicle. Refer to "Lifting and
Jacking the Vehicle: ".
2. 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.
3. Remove the tire and wheel assemblies from the
vehicle. Refer to "Tire and Wheel Removal and
Installation: ".
4. 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.
5. Position the J 8001, or equivalent, on the machined
surface of the wheel hub/axle flange outside of the
wheel studs.
6. Rotate the hub one complete revolution in order to
find the low spot.
7. Set the J 8001, or equivalent, to zero at the low spot.
8. 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)
9. If the runout of the wheel hub/axle flange IS within
specification and the vehicle is equipped with wheel
studs, proceed to step 13.
10. If the runout of the wheel hub/axle flange IS within
specification and the vehicle is equipped with wheel
bolts, proceed to step 19.
11. If the runout of the wheel hub/axle flange is marginal,
the wheel hub may or may not be the source of the
disturbance.
12. 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.
13. 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.
14. Turn the hub one complete revolution to register on
each of the wheel studs.
15. Zero the J 8001, or equivalent, on the lowest stud.
16. 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)
17. If the runout of the wheel studs - stud circle - is
marginal, the wheel studs may or may not be
contributing to the disturbance.
18. 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.
19. Inspect the threads and the tapered seat portion on
each of the wheel bolts for damage.
20. Wheel bolts exibiting damaged threads and/or
damaged tapered seats require replacement.
21. Place the threaded portion of each wheel bolt along
a straight edge to inspect for straightness.
22. Wheel bolts that are not straight require
replacement.
