Vehicle Care 10-83 { WARNING Wheel nuts that are not tight can work loose. If all the nuts on a wheel come off, the wheel can come off the vehicle, causing a crash. All wheel nuts must be properly tightened. Follow the rules in this section to be sure they are. 9. Put the wheel nuts back on with the rounded end of the nuts toward the wheel. Tighten each wheel nut by hand until the wheel is held against the hub. 10. Lower the vehicle by turning the jack handle counterclockwise. Lower the jack completely. WARNING (Continued) To be sure, replace all studs on the wheel. If the stud holes in a wheel have become larger, the wheel could collapse in operation.

When replacing studs, hubs, wheel nuts or wheels, be sure to use GM original equipment parts. { WARNING If wheel studs are damaged, they can break.
