Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Inspect and Replace Tires (if needed)

Inspect Tires
- Check for uneven wear, bulges, or damage.
- If tires are damaged or excessively worn, proceed to replace them.
Replace Tires
- Jack up the vehicle and secure it on jack stands.
- Remove the lug nuts using a socket wrench and take off the damaged tire.
- Install the new tire, ensuring the directional pattern aligns correctly.
- Hand-tighten the lug nuts and lower the vehicle.
- Torque the lug nuts to the manufacturer's specified value.

3. Wheel Alignment

Use a professional alignment machine to check the alignment settings.
Adjust camber, caster, and toe angles according to the manufacturer's specifications.

4. Inspect and Replace Suspension Components (if needed)

Inspect Shock Absorbers
- Check for fluid leakage and physical damage.
Replace Shock Absorbers
- Remove the wheel for easier access to the shock absorber.
- Unbolt the top and bottom mounting points of the shock absorber.
- Replace it with a new shock absorber, tightening to manufacturer's torque specifications.
Inspect Springs
- Look for any cracks or breaks in the coil springs.
- If damaged, replace the springs by removing them from the strut assembly.
