Installation Notes and Tips

Verify rear right position and vehicle fitment before installation. This trailing arm does not include mounting hardware, so reuse or source the required fasteners separately. Because suspension components affect alignment, a professional wheel alignment is recommended after replacement. Confirm the vehicle’s year, make, model, and notes before ordering, especially on 2005-2006 Volkswagen Jetta applications with the specified VIN digit requirement.
