Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Suspension Components

Sub-steps:
- Remove the front wheels to access the suspension parts.
- Check the struts and shocks for leaks or damage; replace if necessary.
  - Tools Required: Socket set, torque wrench.
- Inspect control arms and bushings for wear; replace if cracked or deteriorated.
  - Tools Required: Pry bar, replacement bushings.
- Reassemble the suspension components and torque bolts to manufacturer specifications (usually around 85 ft-lbs for control arm bolts).

3. Examine Exhaust System

Sub-steps:
- Inspect the exhaust system visually, looking for loose hangers or damaged sections.
- Tighten any loose bolts or replace damaged parts as necessary.
  - Tools Required: Ratchet and socket set, exhaust clamps if needed.

4. Check Wheel Bearings

Sub-steps:
- Spin each wheel by hand to check for roughness or play.
- If play is detected, replace the wheel bearing.
  - Tools Required: Hub puller, replacement wheel bearings.
- Reassemble and re-torque the wheel to manufacturer specifications (usually around 76 ft-lbs).

5. Inspect Engine and Transmission Mounts

Sub-steps:
