Installation Notes and Tips

Replace the front left assembly on the same side and verify that the vehicle is listed in the fitment data before installation. Because this is a complete strut and spring assembly, it reduces the need to transfer the spring from the original unit. After installation, inspect alignment settings and confirm proper suspension travel and steering operation.
