Front Axle Pinion Input Seal

Front Axle Pinion Input Seal

This is a replacement front axle pinion input seal, also known as a front steer axle oil seal. It is a critical component that seals the differential where the input yoke connects, preventing gear lubricant loss. This specific part is a unitized seal, meaning it is a one-piece design for easier installation and improved reliability. It is primarily used on Oshkosh and Terex Advance front discharge concrete mixer trucks, which require robust components for demanding job site conditions. Replacing this seal is necessary to fix leaks and prevent damage to the axle's differential from oil starvation.
