Gather tools: jack, jack stands, wrench set, torque wrench, alignment tools, and OBD-II scanner.
Ensure the vehicle is on a level surface and safely raised using jack stands.

2. Tire Inspection and Adjustment

Sub-step 1: Check tire pressure using a tire gauge and adjust to manufacturer specifications.
Sub-step 2: Inspect each tire for uneven wear; replace tires if necessary.
Sub-step 3: Rotate tires if uneven wear is present to promote even wear across all tires.

3. Suspension Component Inspection

Sub-step 1: Visually inspect the shocks, struts, and bushings for signs of damage or leaking fluid.
Sub-step 2: Replace any worn or damaged suspension components with OEM parts.
Sub-step 3: Tighten all bolts to the manufacturer's specifications using a torque wrench.

4. Wheel Alignment

Sub-step 1: Use alignment tools to check the camber, caster, and toe settings.
