Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC1708
Delphi TC6370 front right upper control arm with ball joint for the 2004-2008 Ford F-150 and other vehicles holds the front right wheel in position and lets it move with the suspension. It is sold as a control arm and ball joint assembly, so the joint is part of the same piece.
A clunk over bumps, loose or wandering steering or uneven front tire wear can mean this arm or its ball joint is worn. A worn sway bar link or a tired shock absorber can show up the same way, so find the source of the noise or wear before you replace anything.
This Delphi control arm is a direct-fit replacement for the 2004-2008 Ford F-150, the 2006 Ford Expedition and the 2006-2008 Lincoln Mark LT.
