Quiet a clunking, sloppy front end and keep the lower control arm located precisely with the Delphi Suspension Control Arm Bushing Kit TD4454W. This front lower bushing kit drops in as a direct-fit replacement for the 2003-2006 Ford Expedition and 2003-2006 Lincoln Navigator (see the Buyer's Guide tab for engine-level fitment).
The control arm bushings cushion and locate the front lower control arm, isolating road vibration while keeping suspension geometry in place. Worn or cracked bushings can bring on clunking over bumps, imprecise steering, and uneven tire wear — signs this kit may need to be installed.
