Remove the old suspension components carefully. Install the new system by attaching the shocks, springs, and control arms in the reverse order. Torque all bolts to the manufacturer’s specifications and ensure proper alignment. Test the vehicle on a safe, level surface to confirm functionality.
Q4 What are common troubleshooting steps for suspension issues?
What are common troubleshooting steps for suspension issues?
Common suspension issues include noise, uneven tire wear, and poor handling. Start by inspecting the shocks, springs, and bushings for wear or damage. Check for loose or missing bolts and tighten them as needed. Ensure proper tire pressure and alignment. If the problem persists, consider replacing worn components. For persistent issues, consult a professional mechanic to diagnose and resolve the problem effectively.
Q5 How can I optimize the performance of my suspension system?
