Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect Rear Suspension

Using a socket set, remove the rear wheel to access suspension components.
Check the shock absorbers for leaks or damage.
Inspect bushings for cracking or wear.
Tighten any loose bolts to specified torque values (usually around 50-70 lb-ft).

3. Check Differential Fluid

Locate the rear differential cover and remove it using a socket set.
Inspect the fluid for contamination or low levels.
If fluid is low, refill with the manufacturer's recommended rear differential oil (typically 75W-90).
Replace the differential cover and torque bolts to manufacturer's specifications (usually around 30 lb-ft).

4. Inspect Wheel Bearings

Spin the rear wheels by hand to check for any roughness or play.
If roughness is detected, remove the brake drum or rotor to access the bearings.
Replace any worn bearings with new ones, ensuring proper lubrication and installation.

5. Examine Tires

Visually inspect the rear tires for uneven wear patterns or damage.
Rotate tires if necessary or replace them if they are worn out.
Ensure tire pressure is at the recommended PSI.
