2004 Cadillac Escalade EXT Differential

You need to raise the vehicle, remove the tire and wheel assembly, the brake caliper, the rear cover and the gasket, the pinion shaft locking bolt, the pinion shaft, and the shaft part way. Rotate the case until the pinion shaft touches the housing. On axles with a locking differential, use a screwdriver, or a similar tool, to enter the differential case and rotate the lock until the lock aligns with the thrust block. You also need to push the flange of the Axle Shaft (1) toward the differential and remove the C-lock from the button end of the axle shaft and the axle shaft from the housing.

You need to raise the vehicle, remove the tire and wheel assembly, the axle shafts, and the differential assembly, install the smallest expanding driver and the small driving washer, align the separation lines between the expanding driver and the expander assembly, assemble the expander assembly and the drive bar extension, insert the J 33049 into the axle tube and through the Axle Shaft Seal, turn the driving bar clockwise, and drive out the seal.

You need to support the propeller shaft, mark the propeller shaft, disassemble the snap rings, place the universal joint, and place J 9522-3 on the open horizontal bearing cups. Press the lower bearing cup out of the yoke ear, rotate the propeller shaft, press the opposite bearing cup out of the yoke, mark the orientation of the slip yoke, remove the cross and the remaining universal joint parts, inspect the retaining ring grooves for dirt, corrosion, or pieces of the old ring and the bearing cup bores, and clean the retaining ring grooves.
