What It Helps Address

• Corrosion or fatigue in the original lateral arm assembly

Installation Notes and Tips

Install this lateral arm in the rear left upper rearward position only on the listed Lexus applications. Verify mounting hole diameter, bushing orientation, and suspension position before installation. Because this is a bolt-on replacement arm, proper torque and a final wheel alignment are recommended after service. Part number 526-199 should be matched to the vehicle fitment before ordering.
