Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and securely raise it using a jack and jack stands.
Disconnect the battery to avoid any electrical issues during repairs.

2. Tire Balancing

Remove the wheel using a socket set.
Mount the wheel on a tire balancing machine.
Adjust balance by adding or repositioning weights as necessary.
Reinstall the wheel and torque the lug nuts to manufacturer specifications (typically 140 lb-ft).

3. Tire Inspection and Replacement

Examine the tire tread depth and sidewalls for any visible damage.
If tires are worn unevenly, consider replacing them.
Ensure all tires are inflated to the recommended pressure (usually found on the driver’s door jamb).

4. Wheel Alignment

Use a wheel alignment machine to check the alignment angles (camber, caster, toe).
Adjust the alignment settings as needed to meet manufacturer specifications.
Test drive the vehicle to ensure it tracks correctly.

5. Suspension Inspection

Inspect control arms, tie rods, and ball joints for excessive play or wear.
Replace any worn suspension components using appropriate tools (wrenches, sockets).
Torque new components to manufacturer specifications.

6. Brake Rotor Check

Remove the wheel and inspect the brake rotor for warping or uneven wear.
If the rotor is damaged, replace it with a new rotor.
Ensure brake pads are in good condition and replace if necessary.
