I am starting to source parts for rebuilding a set of Rubi Dana 44 axles and I have found a few listings that lead me to believe there is a difference between the rebuild kits since many state specifically for Rubicon models. Are the parts like bearings and shims different from a standard Dana 44 carrier and the Rubicon lockers? The only difference I see in some of the kits is the inclusion of the inner seal that goes on the front, but the other parts look identical to a stamdard Dana 44.
