Keep the front suspension tight and steering precise with the Beck/Arnley Suspension Ball Joint 101-3781, a front lower ball joint that pivots the steering knuckle and control arm while carrying suspension loads. It drops in as a direct-fit replacement for many foreign-nameplate Mercedes-Benz models, including the 1984-1989 190D, 1984-1991 190E, 1987-1989 260E, 1988-1993 300CE, 1986-1993 300E, 1990-1993 300SL, 1988-1993 300TE, 1992-1993 500E, 1990-1993 500SL, 1986-1989 560SL, 1994 E500, 1994-1997 SL320, 1994-1995 SL500 and more — see the Buyer's Guide tab for the full list.

  • OE form, fit and function: engineered as a direct replacement built to Beck/Arnley requirements and specifications for foreign-nameplate applications.
  • Corrosion protection: coated or plated to resist corrosion.
  • Hardware supplied as needed: necessary hardware is provided as required for a complete installation, with functionality that matches the original design requirements.
  • Application specific: matched to this vehicle for a confident install.

A worn ball joint may show up as clunking or popping over the front suspension, imprecise steering, or uneven tire wear — signs this part may need replacing. If a failed front lower ball joint is the cause, this unit replaces it. Replacing ball joints in matched pairs is good practice for balanced handling.

Frequently Asked Questions

What does this ball joint do?

It serves as the front lower pivot connecting the steering knuckle to the control arm, allowing the wheel to steer and the suspension to move while carrying load.

Which vehicles does the 101-3781 fit?

It's a direct-fit replacement for many Mercedes-Benz models such as the 190E, 300E, 300SL, 500SL, 560SL, E500, SL320 and SL500. Check the Buyer's Guide tab for the complete application list.

How do I know my ball joint is worn?

Common signs include clunking or popping over bumps from the front suspension, loose or imprecise steering, and uneven tire wear. Have the cause diagnosed before replacing.

Is mounting hardware included?

Necessary hardware is supplied as needed for a complete installation, and its functionality matches the original design requirements. Consult the vehicle service information for correct fasteners and torque.

Should I replace both sides at once?

It's sold individually. Replacing the left and right ball joints as a matched pair is good practice for balanced, even handling.
