Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect and Replace Tires (if necessary)

Remove the lug nuts using a tire iron or impact wrench.
Lift the vehicle using a jack and secure it with jack stands.
Inspect each tire for uneven wear, bulges, or damage.
If defects are found, replace the tire with a new one of the same size and specifications.
Reinstall the wheel and hand-tighten the lug nuts, then lower the vehicle.
Torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).

3. Check and Replace Drive Shaft or CV Joints (if necessary)

Raise the vehicle and secure it on jack stands.
Inspect the drive shaft for any visible cracks or bends.
Check the CV joints for torn boots or excessive play.
If any issues are found, remove the damaged component:
- For a driveshaft: Remove the bolts connecting it to the rear differential and transmission.
- For CV joints: Remove the axle nut and any retaining clips.
Replace with a new part and reassemble in reverse order.

4. Inspect and Replace Engine/Transmission Mounts (if necessary)

Open the hood and visually inspect the engine mounts for cracks or separation.
Use a pry bar to check for excessive movement.
To replace, remove the bolts securing the mounts to the frame and engine.
Install new mounts in the same position and torque to manufacturer's specifications.
