Delphi TC3268 Suspension Control Arm - Rear Left Upper Center

OE-Style Rear Suspension Control Arm

Delphi TC3268 is a standard replacement suspension control arm for the rear left upper center position on select Mercedes-Benz vehicles. Built from stamped steel with rubber bushings, it is intended to restore rear suspension geometry and consistent handling on applications such as the Mercedes-Benz ML350, GL450, and R350.

Delphi applies OE-focused dimensional and material analysis to help ensure proper fit and function. This rear camber strut replacement is built for vehicles that need a direct-fit suspension arm with the correct mounting dimensions and bushing design.

Detailed Description

Delphi TC3268 is a rear suspension control arm engineered for OE-style replacement on Mercedes-Benz SUVs and crossovers that use a rear left upper center camber strut. The stamped steel design provides a rigid mounting structure, while the rubber bushings help isolate road vibration and maintain suspension articulation. With a 362.0 mm distance between mounting holes, this arm is built to match the original application dimensions for proper alignment and suspension response. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

Compatible With Mercedes-Benz ML350, GL450, GL550, R350, and related rear suspension applications listed below, Delphi TC3268 supports accurate rear camber control on vehicles from 2006 through 2013. It is a practical replacement when the original arm is worn, bent, or causing alignment concerns.

What It Helps Address

• Rear suspension looseness or clunking from worn bushings
• Uneven rear tire wear caused by incorrect camber control
• Alignment drift after suspension wear or component fatigue
• Excess movement in the rear left upper center suspension link
• Restoration of factory-style rear suspension geometry

Installation Notes and Tips

• Verify the rear left upper center position before installation.
• Confirm fitment by year, make, model, and camber strut application.
• Inspect adjacent suspension components and alignment settings during replacement.
• Because mounting hardware is not included, reuse or source hardware as needed based on the vehicle condition.
• Professional alignment is recommended after installation.

Quality Assurance

Delphi tests its aftermarket steering and suspension components under extreme temperature and corrosion conditions, including sub-zero and high-heat exposure plus extended salt-spray testing. The brand also uses dimensional and material analysis to support OE-level compatibility for the intended application.
