Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect Rear Suspension

Sub-steps:
- Lift the rear of the vehicle using a jack and secure with jack stands.
- Visually inspect all suspension components for cracks, excessive wear, or loose fittings.
- Wiggle components to check for play, particularly in bushings and joints.
Tools Required: Jack, jack stands, socket set.
Safety Warnings: Ensure the vehicle is securely supported before working underneath.

3. Check Rear Differential

Sub-steps:
- Locate the rear differential and remove the fill plug.
- Check fluid level; it should be at the bottom of the fill hole.
- If low, add the recommended differential fluid until it begins to seep out of the hole.
- Inspect for any signs of leaks around the differential seals.
Tools Required: Socket set, fluid pump, differential fluid.
Safety Warnings: Be cautious of hot fluid if the vehicle has been running.

4. Inspect Rear Axle

Sub-steps:
- Check the axle for any visible signs of damage, such as dents or bends.
- Verify that the axle nuts are properly torqued to the manufacturer specifications.
- If any damage is found, replace the axle assembly as needed.
Tools Required: Torque wrench, socket set.

5. Reassemble and Lower Vehicle

Sub-steps:
- Reinstall any components that were removed for inspection.
- Lower the vehicle carefully from the jack stands.
- Perform a final visual check to ensure all tools are removed and components are secure.
