1. Preparation

Tools Required: Jack and jack stands, wheel chocks, socket set, torque wrench, pry bar.
Ensure the vehicle is parked on a level surface and the engine is off. Apply the parking brake.

2. Inspect and Replace Wheel Bearings

Sub-steps:
1. Lift the rear of the vehicle with a jack and secure it with jack stands.
2. Remove the rear wheel using a socket set.
3. Inspect the wheel bearing by spinning the hub; listen for grinding noises.
4. If noise is present, remove the brake caliper and rotor for access to the bearing.
5. Use a pry bar to remove the bearing from the hub assembly.
6. Install the new wheel bearing and reassemble components in reverse order. Torque all fasteners to manufacturer specifications.

3. Check and Replace Differential Fluid

Sub-steps:
1. Locate the differential fill and drain plugs.
2. Remove the drain plug and allow old fluid to drain completely.
3. Inspect the fluid for metal shavings or discoloration. If contaminated, replace the fluid.
