CAUTION:
When installing the wheel bearing (1) in the knuckle (2) it is important to place the side of bearing with the wheel speed sensor magnetic encoder ring (dark band) (3) in the knuckle first. Otherwise, the wheel speed sensor will not operate correctly.
- Wipe the bearing bore of the knuckle clean of any grease or dirt with a clean, dry shop towel.
- Place the knuckle in an arbor press supporting the knuckle from underneath using Cup (special tool #6310-1, Cup) (4.)
- Place the NEW wheel bearing (5) magnetic encoder ring side down (see above Caution) into the bore of the knuckle. Be sure the wheel bearing is placed squarely into the bore.
- Place Receiver (special tool #8498, Receiver, Axle Shaft Seal) (3), larger inside diameter end down over the outer race of the wheel bearing.
- Place Disc (special tool #6310-2, Disc) (2) into top of Receiver (special tool #8498, Receiver, Axle Shaft Seal). Lower the arbor press ram (1) and press the wheel bearing into the knuckle until it is bottomed in the bore of the knuckle.
- Remove the knuckle and tools from the arbor press.
- Install a NEW snap ring (2) in the knuckle using an appropriate pair of snap ring pliers (1). Make sure the snap ring is fully seated.
- Place the knuckle in an arbor press. Support the knuckle from underneath using Remover/Installer (special tool #MB-990799, Remover/Installer) (3), smaller end up against the wheel bearing inner race.
- Place the hub (4) in the wheel bearing making sure it is square with the bearing inner race.
- Position Remover/Installer (special tool #9712-2, Plug, Press) (2) in the end of the hub. Lower the arbor press ram (1) and press the hub into the wheel bearing until it bottoms.
