  A: The replacement of front drive axle inner axle seal or bearing requires these key tools: certain tools are necessary for this job: j 8092 universal driver handle (J 8092), j 2619-01 slide hammer (J 2619-01), j 29369-1 bushing and bearing remover (J 29369-1), j 29369-2 bushing and bearing remover (2-3 inch) (J 29369-2), j 36609 axle tube bearing installer (J 36609), and j 45225 axle seal installer (J 45225). J 8092 universal driver handle (J 8092), j 2619-01 slide hammer (J 2619-01), j 29369-1 bushing and bearing remover (J 29369-1), j 29369-2 bushing and bearing remover (2-3 inch) (J 29369-2), j 36609 axle tube bearing installer (J 36609), and j 45225 axle seal installer (J 45225). Perform this service by first lifting your vehicle while also draining the Differential carrier assembly fluids. Start by taking the inner Axle Shaft and housing assembly from the Differential carrier case followed by separating Clutch Fork assembly components and the inner Axle Shaft from the inner Axle Shaft housing for right side seal or bearing replacement. Place the inner Axle Shaft housing into a vise while securing it with clamp pressure centered on the mounting flange. To extract an inner Axle Shaft seal or bearing, use either j 29369-1 or j 29369-2 behind the seal or bearing as necessary then attach j 2619-01 to the specified bushing and bearing remover. To replace the left side seal properly mark the correct wheel drive shaft and inner Axle Shaft alignment before disconnecting the wheel drive shaft followed by inner Axle Shaft removal with a hammer and brass drift. Secure the Differential carrier assembly in a vise before using the j 29369-1 or j 29369-2 with the j 2619-01 to remove inner Axle Shaft seal or bearing. Once installation begins start by using j 36609 and j 8092 to fit the right side bearing and then shift to j 45225 with j 8092 for installing the new Axle Shaft seal. When ready insert the inner Axle Shaft slowly with a careful impact then reinstall the Clutch Fork parts before attaching the assembly containing the inner Axle Shaft to the Differential carrier case. After proper inner Axle Shaft seating in the Differential case side gear, install the left side bearing and seal in the same sequence as the right side. Begin by installing the front Differential carrier assembly and add the correct fluid to complete the operation while lowering the vehicle.
