If you've been reading up on a SUSPENSIA control arm review before you order, the Suspensia Suspension Control Arm X15LA0300 is the rear upper control arm that locates the wheel and helps maintain proper alignment geometry. It drops in as a direct-fit replacement for the 2007-2022 Ford Expedition and the 2007-2022 Lincoln Navigator, so it installs in place of the original rear upper arm on those applications.
A control arm pivots at the frame and connects to the knuckle, positioning the wheel through suspension travel while helping keep the tire located correctly. Worn or damaged arms can show up as clunking, uneven tire wear, or a wandering feel — signs the arm may need replacing.
Shoppers looking for a 2007-2022 Ford Expedition control arm or a 2007-2022 Lincoln Navigator control arm will find this part listed for both.
