Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted if needed.
Disconnect the battery to prevent electrical shorts during repairs.

2. Tire Inspection and Replacement

Inspect Tires:
- Check for uneven wear patterns and ensure proper inflation.
Replace Tires (if necessary):
- Use a jack to lift the vehicle.
- Remove the lug nuts with a socket wrench.
- Replace the damaged tire with a new one and torque the lug nuts to the manufacturer’s specification (typically 80-100 lb-ft).

3. Suspension and Alignment

Inspect Suspension Components:
- Check struts, shocks, and bushings for wear.
- Replace any worn components with OEM parts.
Perform Wheel Alignment:
- Use an alignment machine to ensure all wheels are properly aligned.
- Adjust camber, caster, and toe angles as necessary.

4. Drivetrain Inspection

Inspect Driveshaft and CV Joints:
- Check for any visible damage or excessive play in the CV joints.
- Replace any damaged components using appropriate tools (e.g., socket set and torque wrench).

5. Engine and Transmission Mounts

Inspect and Replace Mounts:
- Check for cracks or excessive wear in the mounts.
- Remove the old mounts using a socket set and install new ones, ensuring to torque to specifications.
