GM 90498568
Hub

With the unit, there is support of the vehicle and removal of tire and wheel assembly, for service and repair of rear suspension Wheel Bearing to be done. Separate the outer tie rod from the rear knuckle and employ the j42066 (Holding Tool) in association to a 1/2 in. Breaker bar to oppose hold the rear Wheel Hub while allowing the Drive Shaft to suspend up. Release the wheel Drive Shaft bolts the wheel Drive Shaft which connects the rear Wheel Hub flange, brake pipe clip at the lower Control Arm, brake pipe and rear brake caliper to be suspended so as to keep the brake system closed. Remove the Brake Disc rotor set screw and Brake Disc rotor, adjusting the parking brake if necessary. Use the j42072 (10 mm Deep Well Socket) in order to remove three out of four brake backing plate bolts to facilitate the process of installing the rear Wheel Hub puller pin. Mount the parts j42094-2 (Spacer) and j42094-1 (Holding Fixture) on the rear Wheel Hub flange without its nut in order to secure it while it is removed; then remove the nut. Apply some of the j23444-a (High Pressure Lubricant) on the threads of the j42094-3 and then fix the j42094-4 (Threaded Arbor) with the j41506-3 on the board. Then place the j42094-5 (Ball Head) on the j42094-3. Join the j42094-10 (Thrust Bearing) to j42094-4 and then to j42094-1 using the three supplied bolts to connect the assembly and then turn the j42094-3 clockwise to remove the rear Wheel Hub flange. Screw the three j42094-7 (Threaded Spacer Pin) into the rear knuckle attach j42094-1 with the stem pointing up and turn j42094-3 clockwise to press out rear Wheel Hub. Remove the Wheel Bearing retaining ring, install the j42094-6 (Bearing Remover)to the end of the threaded driver, then turn the j42094-3clockwise thereby pressing out the bearing. To install, thread j42094-8 (Bearing Installer) through the Wheel Bearing and install j42094-9 (Hub Installer) and j42094-11 (Spacer) onto the shaft of j42094-3 then thread j42094-8 into j42094-3. Hold the j42094-3 and turn the j42094-4 to press in the Wheel Bearing and seat until you release the j42094-8. Replace the Wheel Bearing retaining ring, hold the j42094-1 against the j42094-7, and remove the anchoring bolts of the j42094-4. Pass the rear Wheel Hub through the j42094-3, taking care not to bind the rear Wheel Hub within the Wheel Bearing by aligning the rear Wheel Hub on the j42094-3 by turning it by hand to achieve a keyway, then draw the rear Wheel Hub into the Wheel Bearing either by holding the j42094-3 and torqueing the j42094-4 clockwise then tightening the j42094-3 before the head swells and causes precision fitting the chamber within the head during execution. Take out the tool assembly, attach the special tools to the rear wheel flange, attach the rear Wheel Hub flange, and make sure spline alignment is proper. Press down on the rear Wheel Hub flange fully over the rear Wheel Hub by turning the j4209404 clockwise while counter-holding with the j42094-3 then remove the j42094-4, j42094-3, j42094-10 and j42094-1 all remaining with the j42094-1 and the j42094-2 to attach. Put on the rear Wheel Hub nut and tighten it to 300 nm (221 ft. Lbs.) remove the j42094-1 and j42094-2. Install the retaining washer with peening of the rear Wheel Hub nut, the brake backing plate bolt, tighten the back lobe brake backing plate bolts of 50 nm (37 ft. Lbs.) + to 40 degree with the tool j42072 and j36660-a (Torque/Angle Meter). Mount the Brake Disc rotor and screw, tighten the disc brake rotor screw to 4 nm (35 inch lbs) and then install the rear brake caliper, brake pipe clipped. Reattach the wheel Drive Shaft to the rear Wheel Hub flange, counter hold the rear Wheel Hub with the j42066 and tighten the wheel Drive Shaft bolts to 50nm (37ft. Lbs.) + 70 degrees using j36660-a. At last, install the outer Tie Rod End to the Steering Knuckle, tire and wheel assemblage, and lower the vehicle.

Remove the brake caliper assembly bolts from the steering knuckle and take the brake caliper assembly off the steering knuckle, ensuring the brake system remains closed and supporting the caliper assembly to prevent damage to the flex hose.

Install the rear wheel hub nut, tightening it to 300 Nm (221 ft. lbs.), then remove the Holding Fixture and Spacer.
