What It Helps Address
- Rear suspension looseness or clunking from worn arm bushings

- Noise from deteriorated rubber mounting points
- Alignment issues related to rear suspension wear
Installation Notes and Tips
Verify rear right position and confirm vehicle fitment before installation. This trailing arm uses a bolt-on attachment and includes bushings, but mounting hardware is not included. Because suspension fasteners and bushing preload can affect ride height and alignment, professional installation and a post-installation alignment check are recommended. Confirm all mounting hole sizes and attachment points match the original component before service.
