Most common Salisbury style axle assemblies (e.g., Dana Spicer model 44) require the use of a differential spreader in order to achieve the required carrier bearing pre-load during set-up. Stretching the housing casting (or pumpkin) open by sufficient enough force as to allow extra shim to be added to create the pre-load is the method that the OEM manufactures endorse, and most manufacture's have included special spreader sockets in the housing for exactly this purpose. Insufficient pre-load can result in bearing failure, or ring and pinion failure on any differential, and possible oil\/air leakage issues in an Air Locker(TM) Differential. As a part of ARBs Air Locker(TM) Tools range of differential service\/installation equipment, this specialty tool offers an easy, quick and highly effective way of pre-loading these axles.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAllows the housing to be stretched in a safe and controllable way which reduces the risk of causing permanent damage to the housing\u003c\/li\u003e\n\u003cli\u003ePre-drilled with a hole pattern that suits most of the commonly available axle types\u003c\/li\u003e\n\u003cli\u003eSuited to pre-loading shim adjusted Banjo style axle assemblies\u003c\/li\u003e\n\u003cli\u003eComes in a durable carry case with a dedicated powder coated parts tray for easy storage and transport\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eARB Air Locker(TM) Differential Case Spreader\u003c\/p\u003e","brand":"ARB","offers":[{"title":"Default Title","offer_id":51368255914296,"sku":"A00L 0770003","price":659.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/horsepower-asset-421333-4656487-square_dba73ca6-2d3c-48c0-b650-6bf4777e060f.webp?v=1779467830","url":"https:\/\/store.motormia.co\/products\/arb-differential-spreader","provider":"MOTORMIA","version":"1.0","type":"link"}
