What It Helps Address

• Front-end looseness or play from a worn lower ball joint

• Uneven steering response caused by joint wear
• Restoring proper suspension articulation at the front lower control arm
• Replacing a damaged or corroded press-in ball joint

Installation Notes and Tips

Fits 2003-2009 Lexus GX470, front lower; 2003-2009 Toyota 4Runner, front lower; and 2007-2009 Toyota FJ Cruiser, front lower. Because this is a press-in ball joint, proper removal and installation tools are recommended. Verify thread direction, stud taper, and position before installation, and inspect the surrounding control arm and hardware for wear. Delphi TC4259 should be matched to the vehicle’s front lower suspension configuration before service.

Delphi subjects its steering and suspension components to extreme temperature and salt-spray testing, along with dimensional and material analysis, to support OE-style performance and fit. The brand’s OE safety background is applied to its aftermarket steering portfolio, and Delphi TC4259 is built to meet standard replacement expectations for the listed Toyota and Lexus applications.
