Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, torque wrench, alignment tool.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Tire Inspection and Pressure Adjustment

Check each tire's pressure using a tire pressure gauge.
- Adjust the pressure to the manufacturer’s recommended PSI.
Inspect tires for bulges, cracks, or uneven wear patterns.
- If any defects are found, replace the affected tire.

3. Lug Nut Torque Check

Use a torque wrench to check the lug nut torque.
- Refer to the owner's manual for the specific torque specifications.
- Tighten any loose lug nuts to the specified torque.

4. Wheel Alignment

If the vehicle pulls to one side, perform a wheel alignment.
Use an alignment tool to adjust camber, caster, and toe angles according to the manufacturer’s specifications.
Test drive the vehicle to ensure it tracks straight.

5. Suspension Inspection

Inspect the suspension system components for wear or damage.
- Check bushings, shocks, struts, and control arms.
Replace any worn or damaged components with OEM parts.

6. Balance Wheels

If vibrations persist, have the wheels balanced at a tire shop.
- Ensure that wheel weights are correctly placed on each wheel.
Test drive the vehicle again to confirm the issue has been resolved.
