Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface.
Lift the rear of the vehicle using a jack and secure it on jack stands.

2. Inspect and Replace Differential Fluid

Sub-steps:
1. Locate the rear differential cover and clean around the edges.
2. Remove the differential cover bolts using a socket set.
3. Carefully pry off the cover and allow the old fluid to drain into a pan.
4. Inspect the differential gears for wear or damage.
5. Replace the gasket or sealant on the differential cover.
6. Fill the differential with new fluid (consult owner’s manual for specifications).
7. Reattach the differential cover and torque the bolts to manufacturer specifications.

3. Inspect and Replace Wheel Bearings (if necessary)

Sub-steps:
1. Remove the wheel and brake components to access the hub.
2. Use a bearing puller to remove the old wheel bearings from the hub.
3. Clean the hub assembly with brake cleaner and inspect for damage.
4. Install new wheel bearings using a press or appropriate tools.
5. Reassemble the brake components and wheel, ensuring proper torque specifications.

4. Inspect and Address Suspension Components

Sub-steps:
1. Visually inspect all rear suspension components, including shocks, springs, and control arms.
2. Replace any worn or damaged bushings or shocks.
3. Torque all suspension bolts to manufacturer specifications.
