Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety gloves and glasses.

2. Tire Inspection and Adjustment

Inspect Tires:
- Look for bulges, punctures, or uneven tread wear.
- If any defects are found, replace the affected tire(s).
Adjust Tire Pressure:
- Use a tire pressure gauge to check the pressure of all tires.
- Inflate or deflate tires as necessary to match manufacturer's specifications.

3. Wheel Balancing

Remove Tires:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the wheel bolts using a socket wrench.
Balance the Wheels:
- Mount the wheel on a wheel balancer.
- Add weights as needed to achieve balance, following the machine’s instructions.
Reinstall Tires:
- Reattach the wheel ensuring bolts are torqued to manufacturer specifications (typically 80-100 ft-lbs).

4. Suspension Inspection

Check Components:
- Inspect struts, shocks, control arms, and bushings for visible signs of damage or wear.
- Replace any worn or damaged components using manufacturer-recommended parts.
Reassemble:
- If any components were replaced, ensure they are installed correctly and torqued to specifications.

5. Wheel Alignment

Perform Alignment:
- Use a professional alignment machine to adjust the alignment to manufacturer specifications.
- Ensure all angles (camber, caster, toe) are within the recommended range.
