Q: How to replace the rear axle shaft on 2003 Chevrolet Tracker?
A: To replace the rear Axle Shaft, start with lifting the vehicle and supporting it while positioning a drain pan under the rear axle housing. Drain out the oil by pulling out the filler plug and the Drain Plug. Next, remove the rear tire and wheel assembly on top of it the Brake Drum. Remove the 4 nuts (4, 6) from the bearing retainer studs, and if the abs is installed, also disconnect the Wheel Speed Sensor. Attach Axle Shaft remover (J 45103) to 2 wheel studs and fix wheel hub remover (J 34866) along with 2 wheel nuts. Hook the slide hammer (J 2619-01) to the wheel hub remover and make sure to use minimal force so as not to cause any damage. I'd remove the rear Axle Shaft and the bearing, and if abs exists, i would grind down two opposite sides of the abs reluctor wheel and the rear Axle Shaft bearing retainer ring. Unfortunately, there is no way of doing this that does not damage the volvo engine apart from total removal of the differential assembly with the volvo engine no-go plate. The reason for this limitation is that the volvo engine is held to the car by the volvo engine no-go plate. It is important to note that in prior to removing the volvo engine no-go plate, the volvo engine no-go plate must be removed with the help of a cold chisel in order to unhook the volvo engine from car body appropriately. Use a split-plate bearing puller (J 22912-01) mounted within a hydraulic press to remove the rear Axle Shaft bearing from the rear Axle Shaft while ensuring the appropriate placement of the tool. After removing the bearing retainer, remove seal from retainer and use the ball joint remover (J 43631) or hydraulic press to pickup the 5 wheel studs from axle flange. To install, you shall use split-plate bearing puller (J22912-01) and hydraulic press to install the rear Axle Shaft bearing onto rear Axle Shaft, with concave side facing away from the bearing. If abs is available, press fit the rear abs reluctor wheel and then the rear Axle Shaft bearing retainer ring with the same tool. Check the inner rear axle for a damaged oil seal and replace one if required, apply Wheel Bearing lubricant gm p/n 1051344 (Canadian P/N 993037) on the lip of the seal, and then replace the rear Axle Shaft oil seal. Pump an equal amount of ge motors sealer gm p/n 1052366 onto the bearing retainer ring to the Brake Backing Plate, align the wheel stud with the hole in the flange and install with a wheel nut and washer. And measure the lengths of the left: 711.5 mm and right: 757mm rear Axle Shaft as proper installation of the rear Axle Shaft into housing. Screw 4 nuts (4, 6) on the rear Axle Shaft retainer studs to 23 nm (17 ft lbs.), then reinstall rear Brake Drum, Wheel Speed Sensor if applicable, and rear tire and wheel assembly. Apply teflon pipe sealant, gm p/n 12346004 (Canadian P/N 10953480) on the thread running on the tightening part of the Drain Plug, install, and torque to 25 nm (18.4 ft. Lbs.). Refill the rear axle housing with about 2.2 liters (4.6 pints) of 80w-90 gl5 lubricant, gm p/n 12345977 (Canadian P/N 10953482), to a level level with the bottom of the filler plug hole. Lastly, install the filler plug tighten to 43 nm (31.7 ft. Lbs.), take out the drain pan, and drop the vehicle.
