Solution

1. Preparation

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

2. Tire Inspection and Replacement

Check Tire Pressure:
- Use a tire pressure gauge to measure the pressure in all four tires.
- Inflate or deflate each tire to the recommended pressure.
Inspect Tires:
- Look for any bulges, cuts, or uneven tread wear.
- If any tire is damaged or excessively worn, replace it with a new tire of the same specifications.

3. Wheel Balancing

Remove Wheels:
- Use a lug wrench to remove the wheel nuts and take off the wheels.
Balance Wheels:
- Mount each wheel on a wheel balancer.
- Adjust weights as necessary according to the balancer's readings.

4. Suspension Inspection

Visual Inspection:
- Inspect suspension components including control arms, tie rods, and bushings for any signs of wear or damage.
Replace Worn Components:
- If any components are worn, replace them with OEM parts. Ensure all fasteners are torqued to the manufacturer's specifications.

5. Wheel Alignment

Perform Alignment:
- Use a four-wheel alignment machine to check and adjust alignment settings to manufacturer specifications.
- Adjust camber, caster, and toe as necessary.
