Removal Procedure
WARNING: This page is about a different car, the 2004 GMC Sierra, 2004 GMC Cab & Chassis Sierra, 2004 Chevrolet Silverado, and 2004 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
Observe and accurately reference mark all driveline components relative to the propeller shaft and axles before disassembly. These components include the propeller shafts, the drive axles, the pinion flanges, the output shafts, etc. All components must be reassembled in the exact relationship to each other as they were when removed. In addition, published specifications and torque values, as well as any measurements made prior to disassembly must be followed.
- Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
- Place jack or utility stands (such as GMDE 123-B67313) at the front end of the vehicle.
- Support the axle with jack stands.
- Remove the tire and wheel assemblies. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
- Remove the stabilizer shaft link bolt (5) and the nut (3).
- Disconnect the upper stabilizer shaft link (4) from the frame.
- Reference mark the rear propeller shaft (3) to the rear axle pinion yoke (4).
- Disconnect the propeller shaft from the axle.
Support the propeller shaft as necessary.
- Disconnect the lower mount of the shock absorbers.
- Disconnect the vent hose (1).
- Disconnect the park brake cables. Refer to Park Brake Cable Replacement - Left Rear (w/oNYS) or Park Brake Cable Replacement - Left Rear (w/NYS) and Park Brake Cable Replacement - Right Rear (w/oNYS) or Park Brake Cable Replacement - Right Rear (w/NYS) in Park Brake.
- Disconnect the junction block.
- Disconnect the brake pipe.
- Disconnect the brake pipe fitting bracket from the brake assembly.
- Remove the brake calipers. Refer to Brake Caliper Replacement - Rear (1500 Series) or Brake Caliper Replacement - Rear (2500/3500 Series) in Disc Brakes.
- Support the calipers from the frame using a heavy gauge mechanics wire.
- Remove the nuts and the washers from the spring assembly U-bolts.
- Remove the U-bolts, the anchor plates and the spacers from the axle.
- Remove the axle with the aid of a hydraulic assist.
- Remove the stabilizer shaft U-bolt nuts (4) and the U-bolts (2) from the axle (3) (if necessary).
- Remove the stabilizer shaft (1) from the axle (if necessary).
NOTE:
Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.
