Audi A3 A4 A6 A7 A8 Q3 1997–2012 Suspension Control Arm 3BD422817 4B3407151A

Product overview

This replacement suspension control arm is listed for a range of Audi passenger models, including the A3, A4, A6, A7, A8 and Q3, across model years 1997 to 2012. The listing shows it under OE-reference part numbers 3BD422817 and 4B3407151A. A control arm links the wheel hub or steering knuckle to the vehicle body and keeps wheel alignment stable while the suspension moves, so a worn arm or tired bush can cause knocking, wandering or uneven tyre wear.

Vehicle compatibility

Listing data names Audi A3, A4, A6, A7, A8 and Q3 between 1997 and 2012, with positions quoted for front left, front right, rear left and rear right. No model-by-model fitment table was supplied, and Audi used several different arm designs across these generations. Please match the OE number on your existing arm, or check your VIN with us, before placing an order.

Key features

• New replacement part built to the OE-standard size listed
• Offered in aluminium alloy or steel construction, depending on the option selected
• Suitable for repair work or as an upgrade when refreshing a tired front or rear suspension
• Helps restore steering precision and predictable handling

Replacing a damaged arm also gives you the chance to inspect the surrounding links, bushes and ball joints at the same time.

Technical specifications

Installation requirements

Control arms are safety-critical steering and suspension components, so we recommend fitting by a qualified mechanic. Tighten bushes with the vehicle at normal ride height and torque all fasteners to the manufacturer specification. A wheel alignment should be carried out after installation.

Fitment checks before ordering

Because this listing spans several Audi models and both axles, fitment cannot be assumed from the model name alone. Confirm the position you need and compare the OE number on your old part, or send us your VIN, before ordering.

Package inclusions

Contents as pictured/listed for the selected option; mounting hardware is not included unless stated.
