Solution

1. Preparation

Gather tools and parts needed for repairs.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery if working on electronic components.

2. Tire Balancing

Remove the wheel from the affected side using a socket set.
Mount the wheel onto the wheel balancer.
Spin the wheel to determine the balance and add wheel weights as needed.
Reinstall the wheel and torque to manufacturer specifications (typically around 80-100 ft-lbs).
Repeat for all four wheels if necessary.

3. Suspension Inspection and Repair

Visually inspect all suspension components for wear, including tie rods, ball joints, and control arms.
Replace any worn or damaged components using appropriate tools (e.g., socket set, torque wrench).
- Torque specifications will vary; refer to service manual for exact values.
Align the vehicle using a professional alignment rack following the manufacturer's specifications.

4. Tire Inspection and Replacement (if necessary)

Inspect tires for uneven wear patterns that indicate alignment issues.
If tires are worn out, replace with new tires of appropriate size and type.
Dispose of old tires according to local regulations.
