Detailed Description

Delphi applies OE-focused dimensional and material analysis to this TC1218 control arm assembly to help maintain proper fit and suspension geometry. It is engineered for Mercedes-Benz front left lower applications including the 1994-2002 SL500, 1994-1997 SL320, 1995 E300, 1994 E500, 1990-1993 190E, 1990-1993 300D, 1986-1993 300E, 1990-1993 300SL, 1992-1993 500E, 1990-1993 500SL, 1989-1992 300TE, 1987-1989 260E, 1988-1989 300CE, and 1987 300TD. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Help Address

• Excessive front-end looseness or wandering caused by worn control arm bushings
• Clunking or knocking from the front suspension due to ball joint wear
• Uneven tire wear related to suspension geometry changes
• Steering instability during braking or cornering
• Suspension noise from deteriorated lower control arm components

Installation Notes and Tips

Confirm vehicle fitment by year, model, and front left lower position before installation. Because this assembly uses a press-in ball joint and does not include mounting hardware, inspect related fasteners and surrounding suspension components during service. After installation, perform a professional alignment to verify steering and suspension angles.

Quality Assurance

Delphi tests steering and suspension components across extreme temperature and corrosion conditions, including sub-zero and high-heat exposure plus extended salt-spray testing. The TC1218 is built as a standard replacement part for OE-style fit and performance on select Mercedes-Benz vehicles.
