REMOVAL & INSTALLATION
See Figures 1, 2 and 3
The wheel attaching nuts must be tightened properly to ensure efficient brake operation. Overtightening the nuts or tightening them in the wrong sequence can cause distortion of the brake rotor and drums. Air wrenches are not recommended for tightening wheel nuts. Always use a torque wrench. The correct tightening sequence is a diagonal crisscross pattern.
- Apply the parking brake and block the opposite wheel.
- If equipped with an automatic transmission, place the selector lever in P. For manual transmission models, place the shifter in Reverse.
- If equipped, remove the wheel cover or hub cap.
- Break loose the lug nuts. If a nut is stuck, never use heat to loosen it or damage to the wheel and bearings may occur. If the nuts are seized, one or two heavy hammer blows directly on the end of the bolt head usually loosens the rust. Be careful as continued pounding will likely damage the brake drum or rotor.
- Raise the vehicle until the tire is clear of the ground. Support the vehicle safely using jackstands.
- Remove the lug nuts and the tire and wheel assembly.
- Make sure the wheel and hub mating surfaces as well as the wheel lug studs are clean and free of all foreign material. Always remove rust from the wheel mounting surfaces and the brake rotors/drums. Failure to do so may cause the lug nuts to loosen in service.
- Position the wheel on the hub or drum and hand-tighten the lug nuts. Tighten all the lug nuts, in a crisscross pattern, until they are snug.
- Remove the supports and lower the vehicle. Tighten the lug nuts, in a crisscross pattern (refer to the illustrations provided). Always use a torque wrench to achieve the proper lug nut torque and to prevent stretching the wheel studs.
- Repeat the torque pattern to assure proper wheel tightening.
- If equipped, install the hub cap or wheel cover.
Inspect the wheels on a frequent basis. Replace any wheel that is found to be cracked, bent, severely dented, has excessive runout (warpage) or has broken welds. Inspect the tire inflation valve frequently for wear, leakage, cuts or looseness. Replace any valve whose condition is suspect.
