Solution

1. Preparation

Gather tools and equipment required for the repair.
Ensure the vehicle is parked on a flat surface and safely secured with wheel chocks.
Wear safety glasses and gloves.

2. Tire Inspection and Adjustment

Check Tire Pressure:
- Use a tire pressure gauge to measure each tire's pressure.
- Inflate or deflate tires to the manufacturer's recommended pressure.
Inspect Tires for Damage:
- Visually examine each tire for any bulges, cuts, or foreign objects.
- Replace any damaged tires as necessary.

3. Wheel Balancing

Remove Wheels:
- Loosen lug nuts and lift the vehicle using a jack.
- Remove the wheel and tire assembly.
Balance Tires:
- Mount the tire on a tire balancing machine.
- Follow the machine's instructions to add weights to the wheel if necessary.
- Reinstall the balanced tire back onto the vehicle, ensuring lug nuts are tightened to the manufacturer's torque specifications.

4. Suspension Inspection and Repair

Inspect Suspension Components:
- Visually check shocks, struts, and bushings for any signs of wear or damage.
- Replace any worn or damaged components with OEM or high-quality aftermarket parts.
Perform Wheel Alignment:
- Use a wheel alignment machine to check and adjust the alignment angles to manufacturer specifications.
