Delphi TC1149 Suspension Control Arm - Front Right Lower

OE-Style Front Right Lower Control Arm

Delphi TC1149 is a standard replacement suspension control arm for the front right lower position. It is built with pressed steel construction and includes rubber bushings for a direct-fit service part that supports steering and suspension geometry on select Mercedes-Benz models.

Compatible with 1992-1999 Mercedes-Benz CL500, CL600, 300SD, 300SE, 400SE, 400SEL, 500SEC, 500SEL, 600SEC, 600SEL, S320, S350, S420, S500, and S600 front right lower applications, this Delphi control arm is engineered for OE-level dimensional and material compatibility. Part number TC1149 is also referenced in aftermarket catalogs for the same front right lower Mercedes-Benz suspension application.

Key Features

• Pressed steel control arm construction
• Rubber bushings included
• Standard replacement grade
• Non-adjustable design
• Ball joint not included
• Front right lower position

Detailed Description

Delphi applies OE-focused engineering to its aftermarket steering and suspension portfolio, and TC1149 reflects that approach with dimensional and material analysis aimed at proper fitment. The part is tested for extreme temperature exposure and salt-spray resistance as part of Delphi’s validation process, helping confirm durability in demanding road conditions. For Mercedes-Benz S-Class and coupe applications from the early 1990s through the late 1990s, this control arm restores the front right lower suspension mounting point with a direct replacement design.

What It Helps Address

• Excessive front-end looseness or wandering
• Clunking or knocking from worn suspension bushings
• Uneven tire wear caused by worn control arm components
• Steering instability from degraded lower arm support
• Suspension geometry issues at the front right lower corner

Installation Notes and Tips

Verify the vehicle year, model, and front right lower position before installation. Inspect adjacent suspension components, including bushings, ball joints, and mounting points, for wear or damage that could affect alignment or ride quality. Because the ball joint is not included, confirm whether the existing serviceable components meet replacement standards before beginning the repair. An alignment check after installation is recommended.

Quality Assurance

Delphi validates this control arm through OE-oriented testing and material analysis to support fit and durability across the listed Mercedes-Benz applications. This part cross-references Mevotech Supreme CMS101127 and MK9919 for the same application.
