DIAGNOSIS AND TESTING - TIRE AND WHEEL
RUNOUT
Radial runout is the vertical distance between the
high and low points on the tire or wheel edge.
Lateral runout is the horizontal movement of the
tire or wheel.
Radial runout of more than 0.62 mm (0.024 inch)
measured at the center line of the tread may cause
the vehicle to shake.
Lateral runout of more than 0.800 mm (0.031 inch)
measured near the shoulder of the tire may cause the
vehicle to shake.
Runout should always be measured off the
vehicle and on a suitable balance machine.
Usually radial runout can be reduced by relocating
the wheel and tire on the wheel studs (See Method
1). If this does not reduce runout to an acceptable
level, the tire can be rotated on the wheel. (See
Method 2).
METHOD 1 (RELOCATE WHEEL ON HUB)
Check the accuracy of the mounting surface on the
wheel and the flange of the hub/bearing assembly.
Drive the vehicle a short distance to eliminate any
tire flat spotting that may have occurred from the
vehicle being parked.
Verify all wheel nuts are properly tightened and
torqued in the correct sequence. (Fig. 1).
Use Dial Indicator Set, Special Tool C-3339A, with
25-W wheel, or equivalent, to determine radial
runout (Fig. 2).
Relocate wheel on the mounting, two studs over
from the original position.
