Delphi TC2838 Suspension Control Arm - Rear Left or Rear Left Upper Forward

OE-Style Rear Suspension Control Arm

Delphi TC2838 is a rear suspension control arm built for OE-style replacement on select BMW applications. It uses steel and aluminum construction with natural rubber bushings to support rear suspension geometry and ride control on vehicles such as the BMW 528i, 535i, 550i, 740i, and 750Li.

Delphi applies OE-level dimensional and material analysis to help ensure proper fit and consistent suspension performance. Part number TC2838 is engineered for the rear left upper forward position on the listed BMW models.

Key Features

• Steel and aluminum construction with casting/forged design
• Natural rubber bushings included
• Standard replacement grade for rear suspension service
• Gray bushing color and silver arm finish
• Non-adjustable design for direct replacement use
• Rear left upper forward position coverage on listed BMW applications
• Delphi TC2838 cross-references Beck/Arnley 102-8013 and MOOG RK642863 for the same application

Detailed Description

This Delphi suspension control arm is designed for BMW rear suspension repair where worn bushings, looseness, or alignment-related handling concerns are present. The steel and aluminum build balances strength and weight, while the natural rubber bearing type helps maintain factory-style suspension isolation. Delphi tests components across extreme temperature ranges and salt-spray exposure to support durability in demanding road conditions. If you are replacing a rear left upper forward control arm on a BMW 640i Gran Coupe, 650i xDrive Gran Coupe, 528i xDrive, or 740Li xDrive, TC2838 provides a direct-fit service part for the listed applications.

What It Helps Address

• Rear suspension clunking or looseness from worn control arm bushings
• Uneven tire wear related to rear suspension geometry issues
• Steering or handling instability caused by rear suspension play
• Excess vibration transferred through deteriorated rubber bushings
• Alignment drift after suspension wear on BMW rear suspension systems

Installation Notes and Tips

Verify the rear left upper forward position before ordering, since Delphi TC2838 also appears in rear left fitment listings for select BMW applications. Compare the original arm length, mounting points, and bushing orientation to the removed part before installation. Mounting hardware is not included, and the arm is not adjustable. A professional alignment is recommended after replacement to confirm rear suspension geometry.

Quality Assurance

Delphi uses OE-focused engineering, dimensional analysis, and material validation to support fit and function across aftermarket steering and suspension parts. This control arm is tested for temperature extremes and corrosion exposure to help meet the demands of daily driving and long-term service.
