The tag number associated with this assembly is S933D.\n\nThis axle assembly is rebuilt to exacting standards, ensuring precision and reliability. Zumbrota Drivetrain thoroughly inspects all internal components, including ring and pinions, internal gears, clutches, and carriers, for wear and proper function. As part of the remanufacturing process, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new components.

Gear backlash is set to OEM specifications to ensure proper lubrication and quiet operation.\n\nZumbrota employs an exclusive cleaning process that includes hydro-blasting and sandblasting of internal and external parts, followed by a proprietary deep cleaning method. This ensures the housing is returned to an OEM finish. Additionally, axle tubes are inspected and straightened to meet OEM standards for straightness, and housings are tested for surface wear and cracks.\n\nIt is important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts. The wheel studs are 12 mm, and the wheel bearing surface diameter is 1.71 inches.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870823608632,"sku":"RAA435-2023B-P","price":2884.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-55-posi-traction-differential-carrier","provider":"MOTORMIA","version":"1.0","type":"link"}
