Audi Genuine Suspension Control Arm Bushing - 4M0407183B

Part Details & Function

• Primary Description: Lower Curved Control Arm Bushing (Inner / Rearward)

• Type: Hydro-mounting (fluid-filled bushing designed to absorb heavy vibrations and harsh road shocks better than standard solid rubber bushings)

• Outer Diameter (O.D.): 80mm

• Supersession/Replaced Part: Replaces older part number 4M0407183A

Purpose

This bushing is pressed into the inner pivot point of the front lower rearward control arm (or the lower link depending on the exact suspension design and model). It connects the control arm to the vehicle subframe, helping maintain precise wheel alignment, stabilizing steering under cornering and braking, and minimizing road noise and steering wheel vibrations.
