Is your Marauder a 2003? If so there is a kit for a complete rear rebuild from Ford. There was a TSB for Fleet cars (but us individuals are not good enough to be included) the kit has both axles bearings and fluid. When I had one of mine done the kit was not much more than a single axle cost. Hope this helps. Good luck. And I agree use a rollback. When mine went bad they used a rollback and when they got it off the right rear wheel just fell off. The axle had snapped.
