DIAGNOSIS AND TESTING
WHEEL INSPECTION
WARNING: FAILURE TO USE EQUIVALENT REPLACEMENT WHEELS MAY ADVERSELY AFFECT THE
SAFETY AND HANDLING OF THE VEHICLE. USED WHEELS ARE NOT RECOMMENDED. THE SERVICE HIS-
TORY OF THE WHEEL MAY HAVE INCLUDED SEVERE TREATMENT OR VERY HIGH MILEAGE. THE RIM
COULD FAIL WITHOUT WARNING.
Inspect wheels for:
• Excessive Run Out
• Dents or Cracks
• Damaged Wheel Bolt Holes
• Air Leaks From Any Area or Surface of Rim
Note: Do not attempt to repair a wheel by hammering, heating or welding.
If a wheel is damaged an original equipment replacement wheel should be used. When obtaining replacement
wheels, they should be equivalent in load carrying capacity. The diameter, width, offset, pilot hole and bolt circle of
the wheel should be the same as the original wheel.
STANDARD PROCEDURE - WHEEL REPLACEMENT
The wheel bolts are designed for specific applications. They must be replaced with equivalent parts. Do not use
replacement parts of lesser quality or a substitute design. All aluminum wheels have wheel bolts which feature an
enlarged head. This enlarged head is necessary to ensure proper retention of the aluminum wheels.
Note: Do not use chrome plated lug bolts with chrome plated wheels.
Before installing the wheel, be sure to remove any build up of corrosion on the wheel mounting surfaces. Ensure
wheels are installed with good metal-to-metal contact. Improper installation could cause loosening of the wheel
bolts. This could affect the safety and handling of your vehicle.
To install the wheel, first position it properly on the
mounting surface. All wheel bolts should then be tight-
ened just snug. Gradually tighten them in sequence
(1-5) to the proper torque specification. Never use oil
or grease on the bolts.
