Restore a tight, controlled front suspension with the Beck/Arnley ball joint, MPN 101-3781, a direct-fit front lower ball joint for a long run of classic Mercedes-Benz models. It forms the pivoting connection between the lower control arm and the steering knuckle, letting the suspension travel and the wheel steer while keeping the front end located. It drops in for the 1984-1989 190D, 1984-1991 190E, 1987-1989 260E, 1986-1993 300E, 1988-1993 300TE, 1990-1993 500SL, 1986-1989 560SL, 1994 E500, 1994-1997 SL320 and more — see the Buyer's Guide tab for the full list.
Signs this ball joint may need replacing include clunking or popping over bumps, loose or wandering steering, and uneven front tire wear. Diagnose the cause before replacing, as these symptoms can have other sources. Ball joints wear as a pair — inspecting and replacing both sides is good practice for balanced handling.
