3. Wheel Alignment

Set Up Alignment Machine: Position the vehicle on an alignment rack.
Perform Alignment: Adjust the camber, caster, and toe settings to match manufacturer specifications.

4. Suspension Inspection

Check Components: Visually inspect shocks, struts, control arms, and bushings for signs of wear or damage.
Replace Damaged Parts: If any components are worn, replace them using the appropriate tools.

5. Drivetrain Inspection

Examine Driveshaft and Axles: Inspect for any signs of damage, including torn boots or excessive play.
Replace as Necessary: If components are damaged, replace them following manufacturer specifications.
