Tires: Service and Repair

REMOVAL
1. Remove the wheel cover, if so equipped.
2. With the weight of the vehicle still on the tires, loosen the lug nuts.

CAUTION: Do not use heat to loosen a seized lug nut. Heat can damage the wheel and wheel bearings

NOTE: Do not remove the lug nuts at this time.

3. Raise the vehicle until the wheel and tire assembly clears the floor.
4. Remove the lug nuts.
5. Remove the wheel and tire assembly.

INSTALLATION
1. Position the wheel and tire assembly on the vehicle.

WARNING: WHEN A WHEEL IS INSTALLED, ALWAYS REMOVE ANY CORROSION, DIRT OR FOREIGN MATERIAL PRESENT ON THE MOUNTING SURFACES OF THE WHEEL OR THE SURFACE OF FRONT DISC BRAKE HUB AND ROTOR THAT CONTACTS THE WHEEL. INSTALLING WHEELS WITHOUT PROPER METAL-TO-METAL CONTACT AT THE WHEEL MOUNTING SURFACES CAN CAUSE THE LUG NUTS TO LOOSEN AND THE WHEEL TO COME OFF WHILE THE VEHICLE IS IN MOTION, RESULTING IN LOSS OF CONTROL.

2. Install the lug nuts loosely. Make sure the cone ends of the lug nut face inward.
3. Turn the wheel until one lug nut is at the top of the wheel hub bolt circle. Tighten the lug nut until snug. In a crisscross-type pattern, tighten the remaining lug nuts until snug to minimize runout.
4. Lower the vehicle.





5. Tighten the lug nuts to specification.

CAUTION: Failure to tighten the lug nuts in a star pattern can result m high rotor runout, which will speed up the development of brake roughness, shudder and vibration.

6. Advise the customer that the wheels need to be retightened at 800 km (500 miles) after any wheel change or any other time the lug nuts have been loosened. This is required to permit the wheel clamping system to seat properly so that the lug nuts will hold a uniform clamp load and remain fully tightened.
7. Install the wheel cover, if so equipped.
