Solution

1. Preparation

Gather tools needed: jack, jack stands, wheel chocks, OBD-II scanner, torque wrench, basic hand tools.
Ensure the vehicle is on a flat surface and turn off the engine.

2. Tire Inspection and Replacement

Sub-steps:
- Lift the vehicle using a jack and secure it on jack stands.
- Remove the wheels to inspect for uneven wear or damage.
- If any tires are found to be damaged or worn unevenly, replace them with new tires.
- Reinstall wheels and torque to the manufacturer’s specifications (usually around 100-120 ft-lbs).

3. Drivetrain Component Check

Sub-steps:
- Inspect the driveshaft and CV joint boots for any signs of wear or damage.
- If any parts are damaged, replace them as needed.
- Ensure all bolts and fasteners on the driveshaft are properly tightened.

4. Engine and Transmission Mount Replacement

Sub-steps:
- Locate the engine and transmission mounts and check for cracks or separation.
- Remove the old mounts using a socket set and replace them with new mounts.
- Torque the new mounts to the manufacturer’s specifications (usually around 45-55 ft-lbs).

5. Suspension Inspection and Repair

Sub-steps:
- Inspect control arms, bushings, and links for wear or damage.
- Replace any worn suspension components to restore proper alignment and handling.
- After replacement, have a professional alignment performed.
