FRONT HUB/BEARING

REMOVAL
1. Raise and support vehicle.
2. Remove the front wheel and tire assembly.





3. Remove and inspect the front disc brake caliper (1). Inspect for any damage or wear.





4. Remove and inspect the front disc brake rotor (1). Inspect for any damage or wear.





5. Remove the front wheel hub dust cap (4).
6. Loosen the hub nut bolt then remove the hub nut (3) and then remove the tapered roller bearing (2).
7. Remove the front wheel hub (1) from the spindle.

INSPECTING HUB AND BEARINGS





1. Remove the bolts (1) and inspect the front disc brake dust shield and replace if necessary.

Note: Discoloration may be caused by generated heat due to incorrect bearing end play settings.

CAUTION: Only replace the tapered roller bearing and bearing races in pairs.

2. Inspect the spindle for any discoloration or wear on the bearing seats or the contact surface of the radial seal ring. Replace if necessary.





3. Inspect the front wheel hub (1). Inspect the threaded bores and the rotor teeth for any wear or damage.
4. Inspect the tapered roller bearing (2), bearing races and the radial seal ring. The tapered roller bearings and bearing races can be reused if:
- The tapered rollers and bearing races have a smooth, grey running track.
- No discoloration (indicating, intense heat) is evident.
- The roller cage and the face ends of the tapered rollers are not worn or damaged.
- The bearing races sit tight in the wheel hub.

INSTALLATION





1. Pack the front wheel hub (1) with grease, coat the radial seal ring and also pack the space between the sealing lip and the tapered roller bearing (2) with grease. Install the front wheel hub (1) with the inner tapered roller bearing (2) and the radial seal ring onto spindle.
2. Install the hub nut (3) tight enough to hold the rotor (5) in place.





3. Install the front disc brake rotor (1).





4. Install the front disc brake caliper (6).
5. Adjust the wheel bearing end play.





6. Install the dust cap (4).

CAUTION: Before driving the vehicle, operate the brake pedal several times until pressure in the brake system is built up and maintained.

7. Install the wheel and tire assembly.
