Dorman - OE Solutions Suspension Control Arm and Ball Joint Assembly P/N:520-520
Dorman 520-388 front right lower control arm with ball joint for the 2006-2010 Ford Explorer and other vehicles joins the front right wheel to the suspension through its ball joint. This Dorman control arm from the OE Solutions line is a direct replacement for the original equipment on specific vehicle applications.
A clunk over bumps, loose steering or uneven front tire wear can mean the arm, ball joint or bushings are worn, though a worn tie rod end or sway bar link can cause similar signs. This listing is one arm for the front right; the front left is a separate part, and the two sides are normally replaced together.
As a Ford Explorer control arm it covers the 2006-2010 model years. It also fits the 2007-2010 Ford Explorer Sport Trac and the 2006-2010 Mercury Mountaineer, and the front right position on each calls for one arm.
