Delphi Suspension Control Arm P/N:TC1146
Fit your Lexus with a Delphi control arm and keep the front suspension located, quiet, and controlled. The Delphi Suspension Control Arm TC6627 is the front left lower rearward arm for the 2007-2012 Lexus LS460 — see the Buyer's Guide tab for engine-level applications. As a suspension control arm, it links the chassis to the steering knuckle and, through its integral ball joint, allows the wheel to move through its travel while holding proper geometry.
If a worn LS460 lower control arm is behind clunking over bumps or during turns, loose steering, or uneven tire wear, this replaces it.
