Heavy Duty C5 Front Wheel Bearings - Getting Your Bearings

The bottom bearing bolt is countersunk into the upright as shown. It's necessary to remove the lower ball joint before removing this bolt.

Before removing the lower ball joint, place a floor jack under the lower control arm. Leave 5 inches of clearance between the jack and the arm.

Use a long-handle, 21mm box-end wrench to remove the lower-ball-joint nut.

Use a 3-lb mallet to tap the lower upright and loosen the ball joint. Before tapping, place a piece of wood on the upright in the area shown to avoid damage. The ball joint will fall onto the jack.

Once the ball joint is free, raise the upright to clear the ball-joint stud and rest it beside the stud.

Next, use a T-55 Torx to remove the countersunk third bearing bolt.

Use a flat-blade screwdriver to remove the ABS connector from the metal clip.

Remove the old bearing from the upright. Notice how the ABS metal connector flange is attached to the bearing. This piece will be reused on the new bearing.

Remove the new bearing from its package and install the ABS connector flange.
