Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather necessary tools and safety equipment, including gloves and safety glasses.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable and safe before proceeding.

3. Inspect Drivetrain Components

Check CV Joints and Axles:
- Inspect the CV joints for any tears in the rubber boot or signs of grease leakage.
- If damaged, remove the axle nut using a socket and ratchet, then detach the axle from the wheel hub.
- Replace any defective CV joints or axles as necessary.
Examine Differential and Driveshaft:
- Inspect the driveshaft for any signs of wear or damage.
- Check the differential mounts for looseness; replace if necessary.

4. Inspect Suspension Components

Check Control Arms and Bushings:
- Visually inspect control arms and bushings for wear or cracking.
- Replace any worn bushings or control arms if necessary.
Examine Strut Assemblies:
- Inspect the strut assemblies for signs of leakage or damage.
- Replace any struts that show signs of failure.

5. Reassemble and Lower the Vehicle

Reattach any components that were removed for inspection.
Ensure all bolts are torqued to manufacturer specifications.
Carefully lower the vehicle back to the ground using the jack.
