GM Celebrity/Century/Ciera/6000 1982-1996 Repair Guide




See Figure 1

There are many different aftermarket wheels that can be installed on your car. The procedures given in this information are for the factory original wheels. If your vehicle is equipped with aftermarket wheels, follow any special instructions given by that manufacturer. Pay attention to any special washers, spacers or adapters that may have come with aftermarket wheels.

  1. When removing a wheel, loosen all the lug nuts at least one full turn, before jacking up the car.
  3. Raise and safely support the car.
  5. Finish removing the already loosened lug nuts. Sometimes applying slight pressure on wheel toward car will make it easy to screw them off by hand.
  7. Remove the wheel.
  9. If the wheel is stuck on the hub place at least two lug nuts back on. Only screw them on two or three turns, don't allow them to touch the wheel.
  11. Lower the vehicle back on the ground and rock it side to side. This is safer than shaking a vehicle that is on a jack. After the wheel pops loose, repeat the steps after raise and support the vehicle.

To install:
  1. Place the wheel on the vehicle, hand-tighten all of the lug nuts. If the studs or nuts are rusty, now is a good time to place some light lubricate on them.
  3. After all of the nuts are hand-tightened, lower the vehicle.

Fig. Fig. 1: Use the star pattern sequence when tightening the lug nuts

  1. Further tighten the nuts with a lug wrench until they are all snug. Use the "star pattern" method of skipping every other nut in the tightening sequence until all 5 lug nuts have been tightened.
  3. Finally, using a torque wrench, tighten the lug nuts to specification. Although 100 ft. lbs. (136 Nm) may be suitable for factory-equipped steel wheels, aftermarket wheels may require a different amount. Be careful to observe the recommended torque value.

Uneven tightening of wheel lug nuts can cause early disc brake pad and rotor wear.
