Solution

1. Preparation

Gather tools: OBD-II scanner, jack and jack stands, wheel chocks, socket set, torque wrench, and tire pressure gauge.
Ensure vehicle is parked on a flat surface and engage the parking brake.

2. Tire Inspection and Adjustment

Check Tire Pressure: Use a tire pressure gauge to ensure all tires are inflated to the manufacturer’s recommended pressure.
Inspect Tire Condition: Look for any visible damage or uneven wear patterns. Replace tires if necessary.
Wheel Balancing: If unbalanced, take the vehicle to a tire shop for proper balancing.

3. Drivetrain Component Examination

Inspect Driveshaft and CV Joints: Lift the vehicle, remove the wheels if necessary, and visually inspect the driveshaft and CV joints for any cracks or signs of excessive wear.
Replace Worn Components: If any components are worn, replace them as needed. Use appropriate torque settings when reinstalling.

4. Engine and Transmission Mount Replacement

Check Mounts: Inspect engine and transmission mounts for cracks or separation.
Replace if Necessary: If mounts are worn, remove the affected mounts and replace them with new ones. Torque to manufacturer specifications.

5. Brake System Inspection

Check Brake Rotors: Remove the wheels and check the brake rotors for warping or uneven surfaces.
Resurface or Replace Rotors: If warping is found, either resurface or replace rotors as necessary. Ensure proper torque when reinstalling wheels.
