Help keep the front suspension tight and steering responsive with the Mevotech Supreme Ball Joint MS40521, a direct-fit Ford Edge ball joint that installs in the front lower position on the 2007-2015 Ford Edge, 2007-2015 Lincoln MKX and 2007-2013 Mazda CX-9. This suspension ball joint connects the lower control arm to the steering knuckle, letting the suspension travel while you steer.
Mevotech Supreme parts are engineered in-house with application-specific upgrades built for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks, plus Labor Saver designs to make installs faster.
- Superior toughness: sintered bearings for longer-lasting performance.
- Simple to service: includes a 90-degree SAE grease fitting.
- Accurate fit: presses into the larger flange diameter for an easy, accurate press fit.
- Larger sphere design: an application-specific ball stud system with a larger sphere, plus a thicker, stronger flange that resists deformation during installation and knurling for a snugger grip between connecting points.
Signs this part may need replacing include clunking or knocking over bumps, wandering steering and uneven front tire wear. If a worn front lower ball joint is the cause, the MS40521 replaces it.
