Audi A6 C6 / A8 / VW Phaeton Front Lower Control Arm 4E0407509B / 4E0407506B

Product overview

This new lower suspension control arm is referenced to OE numbers 4E0 407 506 B and 4E0 407 509 B and suits several large Audi and Volkswagen models. It is designed to replace an arm with worn bushes or damage that is causing clunks, vague steering or uneven tyre wear.

Large Audi saloons put considerable load through their front suspension arms, and worn bushes or ball joints are common on higher-kilometre vehicles. Replacing tired arms restores precise steering, reduces noise over bumps and helps protect your tyres from abnormal wear.

Vehicle compatibility

The part listing also mentions Passat and Tiguan, which are not supported by the fitment data. Confirm by OE number or VIN before ordering.

Technical specifications

Installation requirements

Suspension work affects vehicle safety and should be done by a qualified mechanic. Tighten bush bolts with the suspension at normal ride height to avoid premature bush wear, use new fasteners where specified, and arrange a wheel alignment after fitting.

Fitment checks before ordering

Audi multi-link front suspensions use several different arms, and some are side-specific. Compare shape, mounting points and OE number with your existing arm, and verify by VIN before purchase. Photos of your old arm are very helpful.

Package inclusions
