What It Helps Fix

• Rear suspension looseness or instability

• Uneven rear wheel tracking
• Excessive play in the rear left upper suspension link
• Ride quality changes caused by worn lateral arm components

Installation Notes and Tips

Install GS861314 at the rear left upper suspension position only. Verify vehicle year, model, and trim before ordering, especially on Toyota RAV4, RAV4 Prime, and Venza applications as well as Lexus NX250, NX350, NX350h, and NX450h+ models. Because this arm is non-adjustable, proper alignment should be checked after installation to confirm suspension geometry is within specification.
