Inner Axle Housing Shaft and Housing Replacement (Bravada)

Removal Procedure

Important: Observe and accurately reference mark the positions of all driveline components relative to the propeller shaft prior to disassembly. These components include the propeller shafts, drive axles, pinion flange, inner axle shafts, etc. Reassemble all components in the exact relationship the components had to one another prior to disassembly. Follow the specifications, torque values and any measurement made prior to disassembly in order to maintain the factory system balance of the driveline components. System balance provides a smoother running driveline operation.





1. Raise the vehicle. Refer to Vehicle Lifting.
2. Position a drain pan under the inner axle shaft housing.
3. Remove the right wheel drive shaft. Refer to Wheel Drive Shafts Replacement in Drive Axles, Bearings and Joints.

Important: Be careful not to damage the seal surface when pulling the splined shaft through the seal.

4. Remove the right inner axle shaft from the housing.
4.1. Protect the end of the inner axle shaft housing and the seal with a shop towel.
4.2. Insert a bent screwdriver into the inner axle shaft retaining ring slot.
4.3. Pry the screwdriver against the shop towel in order to disengage the inner axle shaft from the side gear.





5. Remove the two inner axle shaft housing to frame bracket bolts, nuts and washers.
6. Remove the five inner axle shaft housing to carrier bolts.
7. Remove the inner axle shaft housing.
8. Inspect the seal and bearing. Replace as necessary. Refer to Inner Shaft Seal and Bearing Replacement.
9. Clean the sealing surfaces of the inner axle shaft housing and the carrier with a chlorinated solvent.

Installation Procedure





Important: Reassemble all components in the exact relationship the components had to one another prior to disassembly. Follow the specifications, torque values and any measurement made prior to disassembly in order to maintain the factory system balance of the driveline components. System balance provides a smoother running driveline operation.

1. Apply a bead of sealer GM P/N 12345739 or the equivalent to the carrier sealing surface.
2. Install the inner axle shaft and the housing assembly.

Notice: Refer to Fastener Notice in Service Precautions.

3. Install the five inner axle shaft housing to the carrier assembly bolts.
^ Tighten the bolts to 48 Nm (36 ft. lbs.).





4. Install the inner axle shaft housing to frame bracket bolts, nuts and washers.
^ Tighten the nuts to 98 Nm (72 ft. lbs.).
5. Install the right wheel drive shaft. Refer to Wheel Drive Shafts Replacement in Drive Axles, Bearings and Joints.
6. Inspect the axle lubricant level and add as needed. Use the proper fluid. Refer to Lubrication Specifications.
7. Lower the vehicle.
