22 - 12 TIRES AND WHEELS
DIAGNOSIS AND TESTING (Continued)
METHOD 1 (RELOCATE WHEEL ON HUB)
Check accuracy of the wheel mounting surface;
adjust wheel bearings.
Drive vehicle a short distance to eliminate tire flat
spotting from a parked position.
Verify all wheel nuts are tightened and torqued in
the correct sequence (Fig. 6).
Fig. 6 Wheel Tightening Sequence
Use runout gauge D-128-TR to determine runout
(Fig. 7).
Fig. 7 Run Out Gauge
Relocate the wheel on the mounting studs, two
studs over from the original position.
Retighten wheel nuts until all are properly
torqued. This will prevent brake distortion.
Check radial runout. If still excessive, mark tire
sidewall, wheel, and stud at point of maximum
runout (Fig. 8) and proceed to Method 2.
METHOD 2 (RELOCATE TIRE ON WHEEL)
Rotating tire on wheel is particularly effective
when there is run out in both tire and wheel.
Remove tire from wheel and remount wheel on hub
in former position.

Check the radial runout of the wheel (Fig. 9). The
radial runout should be no more than 0.762 mm
(0.030 inch).
