Mevotech Supreme Suspension Ball Joint P/N:MK9009
Help keep the front suspension tight and the steering precise with the Mevotech Supreme Front Lower Suspension Ball Joint MK8477, a direct-fit replacement for the 1989-1997 Ford Thunderbird, 1993-1998 Lincoln Mark VIII, and 1989-1997 Mercury Cougar. This joint connects the front lower control arm to the steering knuckle, letting the suspension travel while the wheel steers. If a worn ball joint is behind clunking over bumps, wandering steering, or uneven tire wear, replacing it addresses those signs.
