Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is safely parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Inspect and Replace Tires (if necessary)

Sub-steps:
- Remove the wheel covers or hubcaps if applicable using a flathead screwdriver.
- Loosen and remove the lug nuts with a socket wrench.
- Remove the wheel and inspect the tire for bulges or uneven wear.
- If tire damage is found, replace with a new tire, ensuring it matches the specifications (size and load rating).
- Reinstall the wheel, hand-tighten the lug nuts, and lower the vehicle.
- Torque the lug nuts to manufacturer specifications (typically 80-100 lb-ft).

3. Inspect and Repair Suspension Components

Sub-steps:
- With the vehicle raised on jack stands, inspect the lower control arms, bushings, and struts for wear or damage.
- If any components are worn out, replace them with OEM parts.
- Reassemble components, ensuring all fasteners are tightened to the specified torque values.

4. Inspect Drivetrain Components

Sub-steps:
- Check driveshaft for play or damage by manually rotating it and feeling for unusual movement.
- Inspect the differential for fluid leaks or noise when turning.
- Replace any damaged components as necessary.
