Solution

1. Preparation

Gather the necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Tire Inspection and Replacement

Sub-steps:
- Remove the wheel covers or hubcaps if applicable.
- Use a socket set to loosen and remove the lug nuts.
- Inspect the tire tread depth and sidewalls for any irregularities.
- Replace any damaged or worn tires with new tires of the same specifications.
- Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).

3. Suspension Component Check

Sub-steps:
- Lift the vehicle using a jack and secure with jack stands.
- Inspect control arms, bushings, and struts for any signs of wear or damage.
- Replace any defective components with OEM parts.
- Make sure to torque new components to the manufacturer’s specifications.

4. Wheel Balancing and Alignment

Sub-steps:
- Remove the wheels and take them to a tire shop for balancing.
- After balancing, have a professional perform a wheel alignment.
- Reinstall the wheels and ensure they are properly torqued.

5. Drivetrain Inspection

Sub-steps:
- Inspect the driveshaft for any play or damage by manually rotating it.
- Check the CV joints for wear; replace if any grease leaks or tears are visible.
- If necessary, replace worn driveshaft or CV joint components.
