Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Wear gloves and safety glasses for protection.

2. Tire Inspection and Replacement

Inspect Tires:
- Check for visible damage, uneven wear, or foreign objects lodged in the tread.
- Measure tread depth using a depth gauge.
Replace Tires (if necessary):
- Use a jack to lift the vehicle and secure it with jack stands.
- Loosen the lug nuts with a socket set and remove the wheel.
- Install new tires, ensuring proper alignment of the lug holes.
- Tighten lug nuts to the manufacturer’s torque specifications (typically around 80-100 ft-lbs).

3. Suspension Component Inspection

Inspect for Wear:
- Inspect control arms, bushings, and struts for signs of wear or damage.
Replace Components (if necessary):
- Remove damaged components using a socket set.
- Install new suspension components and tighten to manufacturer specifications.

4. Wheel Alignment and Balance

Alignment:
- Utilize an alignment machine to check toe, camber, and caster angles.
- Adjust according to manufacturer specifications.
Balance:
- Mount wheels on a balancing machine and adjust weights as needed.
