The Meritor M10-100494 or M10100494 is a genuine Meritor drive axle pinion seal, designed for heavy-duty truck differential applications. Pinion seals serve a critical function at the differential input: they keep gear oil contained at the pinion shaft while blocking road contamination from entering the axle housing. Using the correct OEM seal matters during a differential rebuild or seal replacement service, as an improperly specified seal can lead to premature leaks and axle damage. Sourced directly from Meritor, this seal is sold by Pro Gear and Transmission. Call us to confirm proper fitment for your axle before ordering.
