Keep your rear suspension tracking true with the Dorman - OE Solutions Lateral Arm and Ball Joint Assembly 526-663. It drops in as a direct-fit replacement for the 2005-2010 Scion tC, serving the rear left lower rearward position and combining the lateral arm with a ball joint to locate the wheel and help control rear suspension geometry.

  • Combined assembly: integrates the lateral arm with a ball joint in one pre-assembled unit, so both worn components are replaced together.
  • Application-specific fit: built for the rear left lower rearward corner on the listed Scion tC application.
  • Signs of wear: clunking or knocking over bumps, uneven rear tire wear, or loose, wandering handling can point to a worn lateral arm or ball joint; if this component is the cause, replacing it addresses those symptoms.

Sold individually for the specified corner. Diagnose the source of any suspension noise or alignment issue before ordering, and torque all fasteners to the vehicle service specifications during installation.
