Extract the Differential case screw with the pinion shaft, then disassemble or limit pinion shaft movement when working on locking differentials. Push the Axle Shaft flange towards the Differential by rotating a screwdriver on the lock until alignment with the thrust block then remove the Axle Shaft. Check the condition of each part before replacing any worn-out elements. For an 8-9/8 inch ring gear axle use the Axle Shaft Bearing Remover (J 23689) while a 9 1/2 inch ring gear axle requires the Axle Shaft bearing remover (9 1/2 inch ring gear) (J 29712) for seal removal. Use the slide hammer with adapter (J 2619-01) through the adapter to pull the bearing from its position. For installation use the Axle Shaft bearing installer j 23690 for 8 5/8 inch ring gear axles with the Axle Shaft bearing installer j 29709 for 9 1/2 inch ring gear axles while using the Axle Shaft seal installer j 21128 for 8 5/8 inch ring gear axles or the Axle Shaft seal installer j 29713 for 9 1/2 inch ring gear axles. Apply wheel bearing lubricant to both the axle bearing and seal before installing the Axle Shaft making sure the lock fits snug against the Differential side gear. Secure the pinion shaft while using loctite 242 to maintain thread seal on its screw. The procedure ends with filling the axle with fluid then removing safety stands and lowering the vehicle after putting back the rear axle carrier cover, Brake Drum and wheel and tire assembly.

  Q: How to replace the Front Drive Axle Inner Wheel Seal and Inner Shaft Bearing on GMC Savana 3500?

  A:

  The first step to replace the Front Drive Axle Inner Shaft Seal and Inner Shaft Bearing requires lifting the vehicle while draining the differential carrier assembly fluid. The left side seal replacement requires disconnecting the wheel drive shaft from its inner shaft flange followed by taking off the inner shaft before removing the inner shaft seal cover bolts and assembly. The process to replace the left side bearing requires removal of the differential carrier assembly together with the left inner shaft and inner shaft seal cover bolts and assembly. Apply the J 29369-1 (Bushing and Bearing Remover) to the inner shaft bearing on its backside before connecting the J 2619-01 (Slide Hammer) for pulling out the inner shaft bearing. First remove the inner shaft from the housing after taking out the inner shaft and housing assembly to reach both the right side seal and bearing. Secure the inner shaft housing within a vise while applying the J 29369-1 (Bushing and Bearing Remover) to its back surface followed by attaching the J 2619-01 (Slide Hammer) to pull out the seal or seal along with bearing. Installation of right side bearings requires using the vise to secure the inner shaft housing prior to bearing installation through J 42211 (Axle Bearing Installer) and J 8092 (Universal Driver Handle - 3/4 in - 10). When installing the right side seal use J 42738 (Seal Installer) while carefully guiding the inner shaft through the oil seal. Put the inner shaft inside the housing before reuniting the components of the inner shaft and housing assembly. The owners must use J 42211 (Axle Bearing Installer) along with J 8092 (Universal Driver Handle - 3/4 in - 10) to install the left side bearing while they should also install the inner shaft seal cover assembly followed by securing the cover bolts at 18 Nm (13 lb ft) and guiding the left inner shaft through the oil seal until it contacts the differential case side gear. Use a soft-faced mallet while tapping the retaining ring into its groove until it reaches full seating then obstruct it with a finger to check its locking position. Reinstall the differential carrier assembly to the inner shaft flange as well as the wheel drive shaft and then add the suitable fluid to the differential carrier assembly before lowering the vehicle.
