What It Helps Repair

• Rear suspension looseness or excess movement at the knuckle connection
• Clunking or knocking noises from worn trailing arm bushings
• Uneven rear suspension response caused by deteriorated rubber
• Loss of OE-style support at the rear lower mounting point
• Visible cracking, separation, or wear in the original bushing

Installation Notes and Tips

Install at the rear lower trailing arm location only on the listed vehicles. Inspect the surrounding suspension hardware and mounting surfaces before installation, and verify bushing orientation and press-fit dimensions against the original part. Professional installation is recommended because suspension bushings typically require proper tools and alignment checks after service.
