Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

Tools Required:

Socket set
Torque wrench
Floor jack and jack stands
Differential fluid pump
Oil catch pan
Screwdriver set

2. Check and Replace Differential Fluid

Drain the Differential Fluid
- Place an oil catch pan under the rear differential.
- Remove the drain plug and allow the fluid to completely drain.
Inspect Fluid Condition
- Look for metal shavings or debris in the old fluid.
- If contamination is found, further investigation into the differential internals may be necessary.
Replace Fluid
- Reinstall the drain plug and torque to manufacturer specifications.
- Use a differential fluid pump to fill with new fluid specified by the manufacturer.

3. Inspect and Replace Wheel Bearings (if necessary)

Remove Wheel
- Loosen lug nuts and lift the vehicle using a floor jack. Secure with jack stands.
- Remove the wheel to access the hub assembly.
Check Wheel Bearing Play
- Grasp the hub assembly and check for any play; any noticeable movement indicates a bad bearing.
Replace Wheel Bearings
- Remove the hub assembly and press out the old bearings using a bearing puller.
- Install new bearings and reassemble the hub.
- Reinstall the wheel and torque lug nuts to specification.

4. Inspect Suspension Components

Visual Inspection
- Check for any signs of wear or damage on the suspension arms, bushings, and mounts.
Replace Worn Components
- If any parts are damaged, remove them and replace with OEM or quality aftermarket parts.
