Delphi TC7056 Suspension Control Arm - Rear Left Upper Rearward
OE-Style Rear Left Upper Rearward Control Arm
Delphi TC7056 is a suspension control arm built for the rear left upper rearward position on select Audi applications. It combines an aluminum arm body with rubber bushings to support precise suspension geometry and consistent road feel.
Compatible with 2017-2022 Audi Q7, 2019-2022 Audi Q8, 2020-2022 Audi RS Q8, 2020-2022 Audi SQ7, and 2020-2022 Audi SQ8 in the rear left upper rearward position.
- Brand: Delphi
- Part number: TC7056
- Suspension control arm for rear left upper rearward placement
- Aluminum construction with casting/forged design
- Rubber bushings included; black bushing color
- Dimensions: 470.0 mm length, 128.6 mm width, 92.2 mm height
- Distance between mounting holes: 405.5 mm
- No pre-greasing, grease fitting, or mounting hardware included
Built for OE-Level Fit and Material Control
Delphi applies OE-focused dimensional and material analysis to its aftermarket steering and suspension portfolio, and TC7056 follows that approach for fitment accuracy and part consistency. The arm is tested for extreme temperature exposure and salt-spray resistance to reflect demanding underbody conditions, making it a direct replacement choice for Audi Q7, Audi Q8, and related performance models that use this rear left upper rearward control arm configuration. This part cross-references 4M0 505 397 L and 4M0 505 397 P for the same application.
Common Problems This Part Can Address
- Rear suspension looseness or clunking from worn bushings
- Uneven tire wear caused by control arm wear or geometry shift
- Imprecise rear suspension response during braking and cornering
- Excess movement in the rear left upper rearward suspension link
- Restoring factory-style alignment stability after wear-related replacement
Installation Notes and Tips
Install TC7056 in the rear left upper rearward position only. Verify the existing arm orientation, bushing alignment, and mounting points before removal, and compare the replacement part to the original control arm for length and hole spacing. Because mounting hardware is not included, reuse or source the correct fasteners as required by the vehicle service procedure. A professional alignment is recommended after suspension work on Audi Q7, Audi Q8, RS Q8, SQ7, or SQ8 models.
Quality Assurance
Delphi backs this suspension control arm with OE-derived engineering practices, including dimensional verification and material analysis for proper fitment. The part is also evaluated for temperature extremes and corrosion exposure to support long-term service in demanding suspension environments.
