Get precise steering alignment and quiet control with the MOOG Chassis RK621604 Front Left Lower Suspension Control Arm and Ball Joint Assembly. This integrated arm carries a pre-installed ball joint and drops in as a direct-fit replacement for the 2005-2007 Ford Five Hundred, 2005-2007 Ford Freestyle, and 2005-2007 Mercury Montego (see the Buyer's Guide tab for engine-level detail).
- Pre-installed ball joint: Sealed sockets for maintenance-free operation, so the arm and joint go in as one unit.
- Optimized bushings: Designed for quiet operation and resistance to wear, salt, road grime, and oils.
- Enhanced structural strength: Heat treated to match or exceed OE requirements to help inhibit premature failure.
- Added corrosion protection: Coated studs plus e-coated cast iron and steel construction help resist deterioration.
- Precision tolerances: Engineered for easy installation and steering alignment right out of the box.
Signs this front lower control arm assembly may need replacing include clunking on acceleration, deceleration, or over bumps, vibration, uneven tire wear, and loose or wandering steering.
