Tire and Wheel Installation

CAUTION: Before installing the wheels, remove any buildup of corrosion on the wheel mounting surface and brake drum or the disc mounting surface by scraping and wire brushing. Installing wheels with poor metal-to-metal contact at the mounting surfaces can cause wheel nuts to loosen. This can cause a wheel to come off when the vehicle is moving, causing loss of control and possibly personal injury.

NOTICE: A torque wrench or J 39544 must be used to ensure that wheel nuts are tightened to specification. Never use lubricants or penetrating fluids on wheel stud, nuts, or mounting surfaces, as this can raise the actual torque on the nut without a corresponding torque reading on the torque wrench. Wheel nuts, studs, and mounting surfaces must be clean and dry. Failure to follow these instructions could result in wheel, nut, and/or stud damage.

INSTALL OR CONNECT

^ Tools Required:
- 0 - 300 Nm (0 - 200 ft. lbs.) Torque Wrench
- J 39544 - GM Wheel Nut Torque Adapters (For uses with pneumatic impact)

1. Wheel and tire assembly in position on the hub/rotor, and lug nuts installed loosely.
2. Turn the wheel until one nut is at the top of the bolt circle.
- Tighten the nut just snug.
3. Snug up the remaining nuts in a crisscross pattern to minimize runout.
Tighten
- Nuts to 130 Nm (95 ft. lbs.).
- Tighten evenly and alternately to avoid excessive runout.
