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 Differential. As a part of ARBs Air Locker Tools range of differential service\/installation equipment, this specialty tool offers an easy, quick and highly effective way of pre-loading these axles.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSpecifics and Features:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\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\u003eComes in a durable carry case with a dedicated powder coated parts tray for easy storage and transport\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\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\u003cli\u003eARB Air Locker Diff Case Spreader\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e","brand":"ARB","offers":[{"title":"Default Title","offer_id":51891775242603,"sku":"ARB-0770003","price":430.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1961\/1987\/files\/ARB-0770003-1.jpg?v=1740047844","url":"https:\/\/caautoparts.com\/products\/arb-0770003","provider":"CA Auto Parts","version":"1.0","type":"link"}
