Audi A4 / A6 Front Upper Control Arm 8E0407505P / 8E0407506C

Product overview

A new upper control arm, listed as a traction control arm, referenced to OE numbers including 8E0 407 505 P, 8E0 407 506 C/E and 8F0 407 506 A. It is made from aluminium and suits Audi multi-link front suspension, where upper arms commonly wear and cause knocking or creaking noises.

Upper arm bushes and ball joints on these Audi suspensions are well-known wear items, particularly on rougher roads. Replacing worn arms restores a quiet, composed ride and accurate steering response.

Vehicle compatibility

No verified fitment table was provided. The part listing mentions Audi A3, A4 and A6, plus Skoda Octavia III, Seat Leon, Mercedes-Benz and Volkswagen, which use entirely different suspension systems. Based on the OE numbers, this arm relates to Audi A4/A6-style multi-link front suspension, but fitment must be confirmed. Please match the part number on your existing arm and verify by VIN before ordering.

Key features

• Aluminium construction
• Upper mounting position

Technical specifications

Installation requirements

As a safety-critical suspension component, this arm should be installed by a qualified mechanic. Upper arm pinch bolts and bush bolts must be torqued correctly, with final tightening at ride height. Inspect the remaining arms at the same time and complete a wheel alignment afterwards.

Fitment checks before ordering

Numbers ending 505 and 506 generally denote opposite sides, and several suffixes exist for different model years. The listing listed some numbers without the leading zero, which we have corrected here. Confirm the exact number, side and vehicle, and verify by VIN before purchase.
