Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Tighten Suspension Components

Sub-steps:
- Lift the rear of the vehicle using a jack and secure it with jack stands.
- Remove the rear wheels to gain access to the suspension components.
- Check all bolts and nuts on the rear suspension for tightness; use a torque wrench to tighten them to manufacturer specifications (typically around 70-90 ft-lbs, but verify with service manual).
- Inspect bushings for wear; replace if cracked or damaged.

3. Examine the Exhaust System

Sub-steps:
- Inspect the exhaust system for any loose or broken hangers, brackets, or clamps.
- Tighten any loose components or replace damaged hangers as necessary.
- Ensure that the exhaust does not come into contact with any other parts of the vehicle.

4. Inspect Wheel Assembly

Sub-steps:
- While the wheels are off, check the condition of the brake pads and rotors for any signs of abnormal wear.
- Inspect wheel bearings for play; replace if excessive movement is detected.
- Ensure that all lug nuts are properly torqued to specifications (around 100-120 ft-lbs).
