Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure electrical safety.

2. Tire Inspection and Replacement

Inspect Tires:
- Check each tire for proper inflation (refer to the owner's manual for recommended PSI).
- Look for bulges, cuts, or other visible damage.
Replace Tires (if necessary):
- Use a jack to lift the vehicle and remove the wheel nuts with a socket wrench.
- Remove the wheel and replace it with a new tire, ensuring the tire is mounted correctly.
- Torque the wheel nuts to the manufacturer's specifications (typically around 100 ft-lbs).

3. Suspension Component Inspection and Repair

Inspect Suspension:
- Check control arms, bushings, and struts for wear or damage.
Replace Worn Components:
- If any components are found to be worn, use the appropriate tools (socket set, wrenches) to remove and replace them.
- Follow torque specifications for new parts as per the manufacturer’s guidelines.

4. Driveshaft Inspection

Inspect Driveshaft:
- Check for any visible damage or looseness in the driveshaft.
Repair or Replace:
- If damaged, use the appropriate tools to disconnect the driveshaft and replace it with a new one, ensuring all bolts are torqued to specification.
