Guide the front wheel through suspension travel and steering with the Dorman - OE Solutions Suspension Control Arm and Ball Joint Assembly 520-217. This front left upper unit installs as a direct-fit replacement for a range of 1997-2004 Ford and Lincoln full-size trucks and SUVs, connecting the frame to the steering knuckle while its integrated ball joint lets the wheel pivot and articulate.
Worn upper control-arm bushings or a loose ball joint can show up as clunking over bumps, wandering steering, and uneven tire wear. If the original left upper arm or its ball joint is the cause, this assembly replaces both at once. The right side uses a separate part; replacing both sides together is good practice for balanced handling, and an alignment should be checked after installation.

What does the Dorman 520-217 do?
It's a front left upper control arm with an integrated ball joint that connects the frame to the steering knuckle, locating the wheel and letting it pivot and travel through the suspension's motion.
Which vehicles does it fit?
A direct-fit replacement for the 1997-2002 Ford Expedition, 1997-2003 F-150 and Lobo, 1997-1999 F-250, 2004 F-150 Heritage, 1998-2002 Lincoln Navigator and 2002-2003 Blackwood. See the Buyer's Guide tab.
What position is this assembly for?
The front left (driver-side) upper position on the listed applications. The right side uses a different part.
Does it include the ball joint?
Yes. The ball joint is integrated into the assembly, so installing this unit renews both the control arm and its ball joint together.
Should I replace both sides at once?
It isn't required, but replacing the left and right upper arms together is good practice for balanced handling. Have an alignment performed after installation.
