Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, flashlight.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety if working on electrical components.

2. Inspect and Tighten Suspension Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Inspect the control arms, bushings, and struts for wear or damage.
3. Use a torque wrench to tighten any loose bolts to the manufacturer's specifications (refer to the service manual for torque values).
4. Replace any damaged components with OEM parts as necessary.

3. Inspect Drivetrain Components

Sub-steps:
1. Check the condition of the drive axles and CV joints for any signs of wear or damage.
2. If damage is found, remove the affected axle by removing the retaining bolts.
3. Replace with a new axle, ensuring it is torqued to the correct specifications.

4. Examine Exhaust and Heat Shields

Sub-steps:
