Replace a worn control arm and help tighten up your front end with the MOOG Chassis Front Right Lower Suspension Control Arm and Ball Joint Assembly RK80402 — a direct-fit unit that drops in on the 2004-2008 Ford F-150 and 2006-2008 Lincoln Mark LT. It combines the lower control arm and an integrated ball joint into one pre-assembled unit for the front right lower position, and comes with all necessary hardware for installation.
- Carbon fiber bearings: Induction-hardened studs paired with a patent-pending carbon fiber-reinforced bearing reduce socket friction compared to typical non-reinforced bearings for longer socket life.
- Optimized bushings: Engineered for quiet operation and resistance to wear, salt, road grime and oils.
- Added corrosion protection: Coated studs and an e-coated cast iron and steel control arm help inhibit premature deterioration.
- Ball stud design: Ball stud shape is designed for fatigue life, compensating for sag and adding extra swing when needed.
The assembly is heat treated to match or exceed OE requirements, and a laser-etched ID marks it as genuine MOOG. Precision tolerances are intended for easy installation and steering alignment. If a worn control arm or ball joint on the front right lower corner is behind your loose steering, uneven tire wear, or clunk on acceleration, this replaces it.

Frequently Asked Questions
Which vehicles does the RK80402 fit?
It is a front right lower control arm and ball joint assembly for the 2004-2008 Ford F-150 and 2006-2008 Lincoln Mark LT. Check the "Vehicles it fits" section to confirm your exact vehicle.
Is this a 2004-2008 Ford F-150 suspension control arm for the left or right side?
This unit is cataloged for the front right lower position. The left side is a separate part, and replacing both sides together is recommended.
Does it come with the ball joint and hardware?
Yes. The ball joint is integrated into the pre-assembled control arm, and MOOG includes all necessary hardware for installation.
What are the bearings made of?
It uses induction-hardened studs with a patent-pending carbon fiber-reinforced bearing, which reduces socket friction compared to typical non-reinforced bearings for longer socket life.
What are signs this MOOG Chassis control arm may need replacing?
Loose or wandering steering, uneven front tire wear, and clunking on acceleration or over bumps can signal a worn control arm or ball joint. Diagnose the cause before replacing.
