Terex Faa Axle Washer-Rf21/Rf22

Terex Faa Axle Washer-Rf21/Rf22

The Terex Front Axle Assembly (FAA) Axle Washer is engineered specifically for Meritor RF21 and RF22 steer axles used in Terex Advance front discharge concrete mixers. Positioned within the front axle assembly, this thrust washer absorbs axial loads and prevents metal-to-metal contact between rotating components, reducing friction and premature wear. It is a vital replacement part during axle rebuilds, king pin service, or routine suspension maintenance to ensure proper wheel alignment and steering responsiveness. Manufactured to OEM specifications, it delivers the durability required for the harsh, high-load environments typical of ready-mix concrete operations.
