LOCK-ON EXTERNAL THREADS WHEEL RETAINING NUT WHEEL NUT COVER
22 - 10 TIRES AND WHEELS
DESCRIPTION AND OPERATION (Continued)
The wheel cover is locked to the wheel using the 5
nuts located in the wheel cover (Fig. 2). The nuts in
the wheel cover, thread onto a special externally
threaded wheel nut (Fig. 3). This is the method used
to retain the wheel cover to the wheel.
Fig. 3 Wheel Nut And Wheel Cover Retaining Nut
The wheel cover retaining nut (Fig. 3) is retained
in the wheel cover and will stay on the wheel cover
when un-threaded from the wheel nut. If required,
the retaining nut for the lock-on wheel cover can be
removed from the wheel cover and replaced as a sep-
arate part of the lock-on wheel cover.
The lock-on wheel cover can not be removed from
the wheel until all 5 of wheel cover retaining nuts
(Fig. 2) are un-threaded from the wheel nuts. Then
the lock-on wheel cover can be removed by hand from
the wheel.
DIAGNOSIS AND TESTING
WHEEL INSPECTION
Wheels must be replaced if they:
• Have excessive run out
• Are bent or dented
• Leak air
• Have damaged wheel lug holes
Wheel repairs employing hammering, heating,
welding or repairing leaks are not allowed.
Original equipment replacement wheels are avail-
able through the dealer. When obtaining replacement
wheels from any other source, they must be equiva-
lent in load carrying capacity. The wheel features
(diameter, width, offset, brake clearance, and mount-
ing configuration) must match the original equip-
ment wheels.
WARNING: FAILURE TO USE ORIGINAL EQUIP-
MENT REPLACEMENT WHEELS MAY ADVERSELY
AFFECT THE SAFETY AND HANDLING OF YOUR
VEHICLE.
WARNING: REPLACEMENT WITH USED WHEELS
IS NOT RECOMMENDED. THE SERVICE HISTORY
OF THE RIM MAY HAVE INCLUDED SEVERE TREAT-
MENT OR VERY HIGH MILEAGE. THE RIM COULD
FAIL WITHOUT WARNING.
TIRE AND WHEEL RUNOUT
NOTE: Runout should always be measured off the
vehicle and on a suitable balance machine.
Radial run out is the difference between the high
and low points on the outer edge of the tire or wheel.
Lateral run out is the total side–to–side wobble of
the tire or wheel.
Radial run out of more than 1.5 mm (.060 inch)
measured at the center line of the tread may cause
the vehicle to shake.
Lateral run out of more than 2.0 mm (.080 inch)
measured at the side of the tire as close to the tread
as possible may cause the vehicle to shake.
Sometimes radial run out can be reduced by relo-
cating the wheel and tire on the wheel studs (See
Method 1). If this does not reduce run out to an
acceptable level, the tire can be rotated on the wheel.
(See Method 2).
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 properly torqued (Fig. 4).
Fig. 4 Tightening Wheel Nuts
Use run out gauge D-128-TR to determine run out
(Fig. 5).
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 run out. If still excessive, mark tire
sidewall, wheel, and stud at point of maximum run
out (Fig. 6) and proceed to Method 2.
