Solution

1. Preparation

Gather all tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Suspension Components

Inspect Components:
- Use a jack and jack stands to lift the vehicle and support it securely.
- Visually inspect the strut mounts, control arm bushings, and sway bar links for damage or excessive play.
Replace Damaged Components:
- If any components are worn or damaged, use a socket set to unbolt them.
  - For control arms, note the torque specifications for reinstallation (typically around 50-70 ft-lbs).
- Install new control arms or bushings by reversing the removal process, ensuring correct alignment.

3. Check and Tighten Exhaust System

Inspect Exhaust:
- Examine the exhaust system from the engine to the tailpipe for loose brackets or damaged hangers.
Tighten or Replace:
- Using a wrench, tighten any loose bolts or replace damaged hangers as needed to ensure the exhaust is secure.

4. Tire Inspection and Replacement

Inspect Tires:
- Check tire pressure and tread depth. Replace tires if they are unevenly worn or below manufacturer specifications.
Rotate Tires:
- If the tires are in decent condition, perform a tire rotation to ensure even wear.
