MOOG Chassis Products Suspension Control Arm and Ball Joint Assembly P/N:RK621270
Replace a worn Ford Expedition control arm with the MOOG RK622137, a rear upper rearward control arm and ball joint assembly for the 2009-2017 Ford Expedition and 2009-2017 Lincoln Navigator. It is a direct-fit replacement for these applications. The ball joint comes pre-installed, so the arm and joint go in as one unit. The arm helps locate the rear suspension, and the ball joint lets the suspension pivot as it moves.
The optimized bushings are designed for quiet operation and resist wear, salt, road grime and oils. Precision tolerances are intended to make installation and steering alignment easier. The necessary hardware is included. A laser-etched ID marks the part as genuine MOOG. See the Buyer's Guide tab for complete fitment details.

This part cross-references / interchanges with the following part numbers:
Will this fit a 2009-2017 Ford Expedition or Lincoln Navigator?
Yes. RK622137 is listed as a direct-fit rear upper rearward control arm for the 2009-2017 Ford Expedition and 2009-2017 Lincoln Navigator. See the Buyer's Guide tab for full details.
Does this Lincoln Navigator control arm come with the ball joint installed?
Yes. The ball joint comes pre-installed in the arm, and MOOG includes the necessary hardware for installation.
What is the carbon fiber bearing in the ball joint?
MOOG pairs induction-hardened studs with a patent-pending carbon fiber-reinforced bearing. It reduces socket friction compared with typical non-reinforced bearings and is designed for longer socket life.
Can the ball joint socket be greased?
Yes. The socket is greaseable, so you can add fresh lubricant to flush out contaminants, which helps reduce corrosion and wear.
What are signs a rear upper control arm may need replacing?
Common signs include clunking or knocking over bumps, a loose or wandering feel, uneven tire wear, or a torn ball joint boot. Diagnose the cause before replacing parts.
