Attempting to pre-load an adjuster nut type differential has proven to be a common cause of incorrectly pre-loaded assemblies and/or damage to the adjuster nut or bearing journal surface. Unfortunately however, most commonly available adjuster nut tools have been designed to suit only a select size or make of adjuster nuts, and many will interfere with the overhang shape of the bearing cap, and so alternative methods such as the hammer and chisel technique are sometimes used. As a part of ARBs new Air Locker(TM) Tools range of differential service/installation equipment, these pliers have been specially designed by ARB to easily and safety accommodate not only the full ARB Air Locker(TM) range of adjuster nuts, but also most OE adjuster nuts also, regardless of size, shape and bearing cap type.
