Wheel Bearing

Replacement of front drive axle inner axle seals and bearings requires these specific tools: the required tools for front drive axle inner axle seal or bearing replacement include 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). Climb the vehicle and drain the Differential carrier assembly first. Wrench out the right side seal or bearing after removing both the inner Axle Shaft and Differential carrier case housing together with the Clutch Fork assembly. Place the inner Axle Shaft housing inside a vise while using clamps exclusively on the mounting flange. When removing the inner Axle Shaft seal or bearing use the specified bushing and bearing remover models j 29369-1 or j 29369-2 positioned behind the seal followed by attaching the slide hammer j 2619-01. To replace only the left side seal begin by marking the inner Axle Shaft-wheel drive shaft alignment and then detach the wheel drive shaft and extract the Axle Shaft with a hammer and brass drift followed by a suitable removal tool for the seal. Both left-side seal and bearing installations require Differential carrier assembly removal and vise-support for following the removal steps again. For installation you need the axle tube bearing installer (J 36609) with the universal driver handle (J 8092) for the right side bearing and new Axle Shaft seal installation alongside the axle seal installer (J 45225) using the universal driver handle (J 8092). Guide the inner Axle Shaft into position while tapping it gently before putting together the inner shaft structures with the Clutch Fork components and mounting the assembly onto the Differential case. Repeat the left side bearing and seal installation if you removed those components previously. Reposition the front Differential carrier assembly after checking the inner Axle Shaft seating then add proper fluid before placing the vehicle on its wheels.

To work on the Wheel Bearing with rear wheel steering you need to lift the vehicle properly then begin your repairs. Take off the wheel and tire then the brake rotor. You must first remove the dust cover from underneath the axle nut while also taking out both the pin and retainer fixed to the wheel drive shaft. Unscrew both the wheel drive shaft retaining nut and Wheel Hub and bearing retaining bolts now. Install the axle remover j 45859 between Wheel Hub and bearing then between wheel drive shaft to disconnect these components from each other before removing Wheel Hub and bearing from vehicle. Position the Wheel Hub and bearing unit onto the vehicle then fasten its retaining bolts with correct torque of 180 nm. Firms the wheel drive shaft retaining nut until it reaches 250 nm (184 ft. Lbs.) torque level then mounts the retaining components onto the wheel shaft nut. Place the dust cap first and add the brake rotor, tire, wheel before lowering the vehicle.

Install and properly align the splash shield before tightening the splash shield bolts to 26 Nm (19 ft. lbs.).

Use the J 21128 (Axle Pinion Oil Seal Installer).

Reinstall the axle shaft, followed by the rear axle housing cover and the tire and wheel assembly.

Remove the wheel hub and bearing retaining bolts and use the Axle Remover (J 45859) to separate the wheel drive shaft from the wheel hub and bearing.

Remove the wheel hub and bearing from the vehicle.

Clean all parts in solvent and air dry, ensuring they are free of grease.

Reinstall the wheel speed sensor to the wheel hub and bearing, securing it with the retaining bolt tightened to 18 N.m (13 lb ft).

Remove the outer bearing, pry out the dust seal, and discard it. Then, remove the inner bearing without spinning the wheel bearings with compressed air.

Reinstall the rotor, the tire and wheel, and lower the vehicle.

Ensure to install the mounting bolts and tighten them to 180 Nm (133 lb ft).

Remove the inner hub bearing and the inner hub bearing cup with a brass drift and hammer.

Install the wheel hub and bearing and splash shield to the vehicle, 25/35 series, followed by the wheel hub and bearing and splash shield to the vehicle, 15 series.

Remove, clean, and inspect it, replacing it if there are any nicks, cuts, brittleness, or compression set.

Install the outer bearing and cup into the wheel hub, driving the bearing cup in with the J 44419 and J 8092.

Clean any grease from the hub/rotor and steering knuckle spindle, avoiding spinning the wheel bearings with compressed air.

Remove the tire and wheel, followed by the rotor.

Begin by raising and supporting the vehicle.

Take out the wheel hub and bearing mounting bolts and remove the wheel hub and bearing along with the splash shield from the steering knuckle.

Finger apply a small amount of grease inboard of each bearing cup in the hub/rotor, then pressure pack or hand pack the bearings, ensuring grease is thoroughly worked into the rollers, cone, and cage.

Clean all corrosion or contaminants and lubricate the steering knuckle bore with wheel bearing grease or an equivalent.

Use the Bearing Installer (J23690).

Ensure the retaining ring is fully seated in its groove.

It is crucial to use a new nut when installing the wheel drive shaft.
