Delphi TC7058 Suspension Control Arm - Front Left Lower Forward

OE-Style Front Left Lower Forward Control Arm

Delphi TC7058 is a suspension control arm for the front left lower forward position on select Audi applications. Built with OE-focused dimensional and material analysis, it is made to match the original fit and suspension geometry for Audi A6 allroad, A6 Quattro, A7 Sportback, Q5, Q5 PHEV, Q5 Sportback, S6, S7 Sportback, SQ5, and SQ5 Sportback models.

Delphi applies OE safety and performance testing to its aftermarket steering and suspension portfolio, including exposure to extreme temperatures and salt spray. The result is a standard replacement control arm engineered for consistent fitment and durable everyday service.

Detailed Description

Delphi TC7058 is a front left lower forward control arm designed for direct replacement service on compatible Audi suspension systems. The aluminum body, bent profile, and rubber bushing design support proper suspension articulation while maintaining the original mounting geometry. Delphi’s OE-based engineering process emphasizes dimensional accuracy and material compatibility, which is important when replacing a control arm on vehicles such as the Audi Q5, A6 Quattro, and SQ5.

This part cross-references Mevotech Supreme CMS701156 for the same application. Delphi TC7058 is also associated with OE-style interchange numbers including 4K0 407 151 and 80A 407 151 A.

What It Helps Address

• Front-end clunking or knocking from a worn control arm
• Excessive play in the front left lower forward suspension position
• Uneven tire wear caused by suspension geometry changes
• Steering wander or reduced directional stability
• Vibration or harshness from deteriorated bushings

Installation Notes and Tips

Verify the vehicle’s position before installation: front left lower forward. Confirm bushing orientation and mounting points against the original part before tightening fasteners. Because mounting hardware is not included, reuse or source the correct hardware separately as required by the vehicle service procedure. After installation, a professional alignment is recommended to restore suspension settings.

Quality Assurance

Delphi subjects its OE-inspired suspension components to extreme temperature and corrosion testing, including sub-zero and high-heat exposure plus extended salt spray testing. That validation process supports consistent performance for daily driving and replacement service on Audi suspension applications.
