1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted.
Wear safety gloves and glasses for protection.

2. Tire Inspection and Replacement

Inspect Tires: Check for uneven wear, bulges, or punctures.
Inflate Tires: Adjust tire pressures to recommended specifications (refer to the owner's manual).
Replace Tires: If tires are worn beyond legal limits or damaged, replace with OEM or high-quality tires.

3. Suspension System Repair

Inspect Suspension Components: Examine shocks, struts, and springs for leaks or damage.
Replace Worn Parts: If any components are found defective, replace them with OEM parts.
Reassemble: Ensure all fasteners are torqued to manufacturer specifications.

4. Wheel Alignment

Perform Alignment: Using an alignment machine, adjust the camber, caster, and toe to factory specs.
Test Drive: After alignment, perform a test drive to ensure stability.

5. Steering System Check

Inspect Steering Components: Look for worn tie rods, ball joints, and bushings.
Replace Parts: If any components are worn or damaged, replace them as needed.
