Dorman - OE Solutions Suspension Control Arm and Ball Joint Assembly P/N:521-554
Dorman 521-381 rear left upper control arm with ball joint for the 2002-2005 Ford Explorer and other vehicles holds the wheel in position while the suspension moves. This Dorman control arm, from the OE Solutions line, is a direct replacement for the original assembly on specific vehicle applications.
A clunk over bumps or uneven tire wear can mean a worn control arm, ball joint or bushing. These signs alone do not prove this arm is the problem, since a worn sway bar link can cause a similar noise.
It is a control arm for the 2002-2005 Ford Explorer and also fits the 2003-2005 Lincoln Aviator and the 2002-2005 Mercury Mountaineer. Only one arm is needed at the rear left upper position. This listing is one arm; the rear right is a separate part, and the two are normally replaced together.
