Delphi TC1109 Suspension Control Arm and Ball Joint Assembly - Front Right Lower

OE-Style Front Right Lower Control Arm

Delphi TC1109 is a standard replacement suspension control arm and ball joint assembly for the front right lower position. It is built for 1984-1986 Mercedes-Benz 190E applications and uses OE-focused dimensional and material analysis to support proper fit and consistent suspension geometry.

For Mercedes-Benz 190E owners looking for a front right lower control arm replacement, Delphi TC1109 combines a stamped steel arm, press-in ball joint, and rubber bushings in a pre-greased assembly. This part is engineered to meet demanding temperature and corrosion exposure testing used in Delphi’s aftermarket steering and suspension portfolio.

Detailed Description

Delphi TC1109 is a front right lower suspension control arm and ball joint assembly made for Mercedes-Benz 190E models from 1984 through 1986. It is a direct-fit standard replacement for the OE-style suspension layout, with a stamped steel arm, rubber bushings, and a press-in ball joint to match the original service configuration. Delphi applies dimensional and material analysis to help maintain OE-to-aftermarket compatibility, and the part is tested for extreme temperature and salt-spray exposure to support durability in real-world conditions. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part May Address

• Front-end looseness or wandering on Mercedes-Benz 190E models
• Clunking or knocking from the front right lower suspension area
• Uneven tire wear related to worn control arm bushings or ball joint wear
• Steering instability caused by suspension joint play
• Restoring proper suspension alignment after wear-related component failure

Installation Notes and Tips

Verify the front right lower position before installation and compare the original arm dimensions, mounting hole spacing, and ball joint style to the replacement part. Because mounting hardware is not included, reuse or source the correct fasteners as needed. After installation, a professional wheel alignment is recommended to confirm suspension geometry and steering response.

Quality Assurance

Delphi uses OE-based engineering, dimensional checks, and material analysis for aftermarket steering and suspension parts. TC1109 is also subjected to temperature testing below -40 degrees C and above 120 degrees C, along with 720 hours of salt-spray exposure, to evaluate performance under harsh operating conditions.
