Replace a worn front left upper arm in one step with the Dorman control arm 520-757, which comes with its ball joint and bushings already installed to save time and labor. It fits many vehicles, among them the 1990-1991 Mercedes-Benz 300D, 1982-1985 Mercedes-Benz 300TD and 1988-1991 Mercedes-Benz 300CE. See the Buyer's Guide tab for the full list and engine details.
This Dorman suspension control arm and ball joint assembly is a direct replacement for the original equipment on the listed applications. It connects the front wheel assembly to the vehicle and pivots on its bushings and ball joint, so the suspension can travel while the wheel stays located.
- Direct replacement: Built to take the place of the original assembly on specific vehicle applications.
- Complete repair: Each assembly includes a pre-installed ball joint and bushings, which saves time and labor.
- Tested quality: Put through Dorman's industry-leading evaluation process, which is aimed at a smooth ride, directional stability and predictable dynamics.
- Corrosion protection: Additional coatings help resist rust and corrosion.
Clunking over bumps, wandering steering, uneven tire wear, a torn bushing or a loose ball joint can be signs this arm may need replacing. If the original upper arm or its ball joint is worn, this assembly replaces both at once. We recommend replacing the matching right-side arm at the same time. A wheel alignment is recommended after installation.
