TRW Automotive Inc (TRW) is recalling certain aftermarket replacement Left Hand and Right Hand Lower Ball Joints, sold for use on Toyota 4Runner, Sequioa and Tundra vehicles. These ball joints were built incorrectly with a vented dust shield on the ball joint stud, which could allow contamination to enter the joint, possibly causing wear and looseness.
The ball stud wear may result in the ball stud separating from the steering knuckle, causing a loss of steering, and increasing the risk of a crash.
TRW will notify owners and will replace the affected ball joints, free of charge. The recall began on June 19, 2017. Owners may contact TRW Wixom Customer Service at 1-248-863-2437 or the ZF Services hotline at 1-800-321-0784.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
