Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lift it using a jack and jack stands.
Safety warning: Disconnect the battery before working on electrical components if necessary.

2. Tire Inspection and Replacement

Inspect Tires:
- Check for bulges, cracks, or uneven wear.
- Measure tire pressure; inflate to manufacturer specifications if low.
Replace Tires (if necessary):
- Remove the wheel using a socket set.
- Install new tires, ensuring they are properly mounted.
- Torque the lug nuts to the manufacturer’s specifications (typically around 100-120 ft-lbs).

3. Wheel Balancing

Balance the Wheels:
- Remove the wheel from the vehicle.
- Use a tire balancer to check for imbalances.
- Add weights as necessary to achieve balance.
- Reinstall the wheel and torque the lug nuts.

4. Suspension and Alignment Check

Inspect Suspension Components:
- Look for any signs of wear or damage in the control arms, bushings, and shocks.
- Replace any damaged parts as needed.
Perform Wheel Alignment:
- Use an alignment machine to adjust camber, caster, and toe settings to manufacturer specifications.
