Fig. Fig. 1: Lug nut tightening sequence

  1. If equipped, remove the hub cap/wheel cover.
  3. Loosen, but do not remove the lug nuts.
  5. Raise and safely support vehicle so the tire is clear of the ground.

Always use a suitable floor jack for raising the vehicle to be serviced. Never use the jacking device supplied with the vehicle for vehicle service. That jacking device is designed for emergency use only to change a flat tire.

  1. Remove the lug nuts, then remove the wheel from the vehicle.

To install:
  1. Install the wheel.
  3. Install the lug nuts, then hand-tighten in a star pattern.
  5. Carefully lower the vehicle.
  7. Final tighten the lug nuts, in a star pattern, to 100 ft. lbs. (140 Nm).


Inspect the tread for abnormal wear, check for nails or other foreign material embedded into the tire. To check for leaks, submerse the wheel assembly into a tub of water and watch for air bubbles.

Wheels must be replaced if they are bent, dented, leak air through welds, have elongated bolt holes, if wheel nuts won't stay tight, or if the wheels are heavily rusted. Replacement wheels must be equivalent to the original equipment wheels in load capacity, diameter, rim width, OFF set, and mounting configuration.

A wheel of improper size may affect wheel bearing life, brake cooling, speedometer/odometer calibration, vehicle ground clearance and tire clearance to the body and/or chassis.

Replacement with used wheels is not recommended as their service history may have included severe treatment or very high mileage and they could fail without warning.

Check runout in all directions (up and down, in and out) using a dial indicator. For aluminum wheels, maximum runout is 0.030 in. (0.762mm) For steel wheels, the specification is 0.045 in. (1.143mm). If the wheel causes a vibration and tire balance does not solve the problem, replace the wheel.
