Advance Faa Housing Inner Bushing Rf21

This inner axle shaft bushing (Terex part number 11932) is a critical drivetrain component for front discharge concrete mixers. It is installed within the front axle housing to support the inner axle shaft, reducing friction and preventing metal-on-metal wear during operation. Specifically engineered for Meritor RF21 and MX23 front steer axles, this bushing ensures proper shaft alignment and extends the service life of the axle assembly. Replacing worn inner bushings is essential for maintaining smooth power transfer and preventing costly damage to the axle housing.
