Solution

1. Preparation

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

2. Inspect and Replace Suspension Components

Raise the Vehicle: Use the jack to lift the rear of the vehicle and secure it with jack stands.
Remove Wheel: Use a socket set to remove the rear wheel on the side where the noise is present.
Check Shock Absorbers:
- Visually inspect for leaks or damage.
- Use a pry bar to check for excessive play in mounting points.
- If faulty, replace with new shock absorbers, ensuring to torque the bolts to manufacturer specifications (typically around 30-40 ft-lbs).
Inspect Control Arms and Bushings:
- Look for cracked or worn bushings.
- Replace any damaged bushings or control arms as necessary, using a torque wrench to tighten bolts to specified values (usually 50-70 ft-lbs).

3. Examine Exhaust System

Inspect Mounts: Check for loose or damaged exhaust hangers that may cause clunking.
Tighten or Replace: If any mounts are found to be loose, tighten them. If damaged, replace with OEM parts.

4. Check Rear Differential and Driveshaft

Fluid Check: Remove the differential fill plug and check fluid level and condition. If low or contaminated, drain and refill with appropriate fluid.
Driveshaft Inspection: Look for any signs of wear or play in the CV joints. Replace if necessary, ensuring to torque bolts to manufacturer specifications.
