Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery as a safety precaution.

2. Tire Inspection and Replacement

Sub-steps:
- Remove the wheel covers or hubcaps.
- Use a tire pressure gauge to check tire pressure; inflate to recommended PSI if necessary.
- Inspect the tread for uneven wear and replace tires if necessary (e.g., if tread depth is below 2/32 inch).
- Reinstall wheel covers or hubcaps after adjustments.

3. Suspension Component Inspection and Replacement

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Inspect control arms, bushings, and struts for signs of damage or wear.
- Replace any damaged suspension components using a socket set and torque to manufacturer specifications (refer to service manual for specific torque values).
- Reassemble and lower the vehicle.

4. Driveshaft and CV Joint Inspection

Sub-steps:
- Examine the driveshaft for any signs of bending or damage.
- Check CV joint boots for tears or leaks; replace CV joints if necessary.
- If replacements are needed, use appropriate tools to disconnect and replace the driveshaft or CV joints according to the manufacturer’s instructions.

5. Engine and Transmission Mount Inspection

Sub-steps:
- Inspect engine and transmission mounts for cracks or separation.
- Replace mounts if they show significant wear or damage using necessary tools, ensuring to torque bolts to specified values.
