Keep your suspension geometry tight and your ball joint smooth with the Delphi control arm TC6744, a front left lower control arm that locates the wheel and links it to the chassis while its integrated ball joint allows the steering and suspension to move. It's a direct-fit replacement for the 2006 Lexus GS300, 2006-2007 Lexus GS430, 2007-2011 Lexus GS350, 2007-2011 Lexus GS450H, 2008-2011 Lexus GS460, 2008-2015 Lexus IS250, and 2008-2015 Lexus IS350 — see the Buyer's Guide tab for engine-level fitment.
Worn control arm bushings or a failing ball joint can cause clunks, uneven tire wear, and loose steering; if the original arm is the cause, this replaces it.
