What It Helps Address

• Rear suspension looseness or instability
• Clunking or knocking from the rear suspension area
• Uneven rear tire wear caused by worn suspension geometry
• Excessive movement from deteriorated bushings
• Restoring OE ride and handling characteristics after wear or damage

Installation Notes and Tips

Install GS861146 at the rear right suspension location only. Verify vehicle year, make, model, and trim before ordering, since fitment varies by application. Inspect adjacent suspension components, fasteners, and alignment settings during replacement to confirm the repair addresses the full source of wear. Because this trailing arm uses bushings and mounting hardware, proper torque procedures and a post-install alignment check are recommended.
