Key Features

• Aluminum construction for the rear suspension
• Rubber bushings included
• Standard replacement grade
• Non-adjustable design
• Ball joint not included
• Fits rear left lower center and rear left lower forward positions, depending on application

Detailed Description

Delphi TC2843 is a suspension control arm designed for OE-style replacement on select Mercedes-Benz rear suspension layouts. Delphi applies OE engineering practices to its aftermarket steering and suspension portfolio, including dimensional and material analysis to support proper fitment. The part is tested across extreme temperature ranges and salt-spray exposure to evaluate durability in demanding road conditions. This makes TC2843 a practical choice for Mercedes-Benz C300, E300, E350, GLC300, CLS550, and other listed applications where rear suspension alignment and arm integrity matter.

This part cross-references MOOG Chassis Products K641424 for the same application.

What This Part Helps Address

• Rear suspension looseness or instability
• Clunking or knocking from the rear control arm area
• Uneven tire wear caused by worn rear suspension geometry
• Excessive play from deteriorated bushings
• Alignment issues after suspension wear or replacement

Installation Notes and Tips

Verify the exact rear position on your vehicle before ordering, since this part is used in both rear left lower center and rear left lower forward locations across different Mercedes-Benz models. Replace the control arm when bushings show cracking, separation, or excessive movement. After installation, a professional wheel alignment is recommended to confirm rear suspension geometry.

Quality Assurance

Delphi uses OE-based engineering, dimensional checks, and material analysis to support fit and performance. The part is also subjected to temperature and corrosion testing, including exposure below -40 degrees C, above 120 degrees C, and 720 hours of salt spray.
