Rear Wheel Drive Shaft Nut Torque Procedure

Notice:

• If service requires the removal and reinstallation of the rear wheel drive shaft retaining nut, it is CRITICAL to follow the torque procedure below. Failure to follow the torque procedure may result in a inadequate torque specification.

• If service requires removal and reinstallation of the rear wheel drive shafts, clean the inboard mating surface of the wheel bearing and the mating surface of the axle shaft of any foreign material prior to assembly. Failure to properly clean the mating surface may result in an inadequate torque specification.

Insert a drift or punch into the brake rotor cooling fins and against the caliper to prevent the wheel hub and bearing from turning.

Begin to install the drive shaft retaining nut onto the drive shaft by hand.
Slowly tighten the nut to draw the drive shaft to the wheel hub and bearing.

Tighten the drive axle spindle nut to 160 N·m (118 lb ft).

• If service requires the removal of the rear wheel drive half shaft retaining nut, it is CRITICAL to follow the torque procedure above. Failure to follow the torque procedure may result in a inadequate torque specification.

• If service requires the replacement of the rear wheel drive shafts, clean the inboard mating surface of the wheel bearing and the mating surface of the axle shaft of any foreign material prior to assembly. Failure to properly clean the mating service may result in an inadequate torque specification.

GMSPO has released a newly designed rear wheel drive shaft assembly for service.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
