Keep your steering tight and your suspension moving smoothly with the Mevotech Supreme Front Lower Suspension Ball Joint MS40553. It drops in as a direct-fit replacement for the 2020-2025 Ford Explorer and 2020-2021 Ford Police Interceptor Utility, pivoting between the lower control arm and steering knuckle so the wheel can steer and travel over the road. Engineered in-house with application-specific upgrades, Mevotech Supreme ball joints are built for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks, with Labor Saver™ designs and hardware that make installs faster.
Worn ball joints can show up as clunking, loose or wandering steering, and uneven tire wear — signs this part may need replacing. Sold individually; if the opposite side is also worn, replacing both as a set helps keep suspension response even.
