Help keep the rear wheel tracking where it belongs with the MOOG RK643655, a 2017-2018 Ford Fusion control arm that also fits the 2017-2020 Lincoln MKZ. It is cataloged for the rear right lower rearward position and is a direct-fit replacement for the listed applications. See the Buyer's Guide tab for engine details.

This suspension control arm connects the wheel assembly to the vehicle's chassis. It locates the wheel, and its bushings let it pivot as the suspension moves.

  • Premium bushings: They come pre-installed, with stiffness optimized to help inhibit noise for a comfortable ride.
  • Structural strength and corrosion protection: MOOG engineers its premium control arms for both. It selects the material and heat treatment to meet the application's requirements.
  • Easy to install: Precision tolerances are intended to make installation and alignment straightforward.

Signs a control arm may need replacing include clunking or knocking over bumps, worn or cracked bushings, uneven tire wear, and an alignment that won't hold. Have the rear suspension inspected to confirm the cause before you replace any parts.
