Gary, some of these rear axle housings had a grease fitting just behind the backing plate flange. The idea was to grease the wheel bearing without pulling the brake drum off. Bad idea! That most of the time forced too much grease into the bearing and out into the drum. If your axles have those fittings, remove them and plug the holes(1/8 pipe). In order to replace the inner axle seals,the whole rear axle must be dismantled, the seals are inside the housing and require a special tool to replace, Macs Ford Parts has that tool. Some guys say that there is a seal that you can install without dismantling the rear end, I have never seen it nor have I used it, might be okay, I dont know for sure. Check the differential filler plug to make sure that the banjo housing does not have too much grease in it. If it is at the proper level, it is not likely that too much grease would be pulled up and out the axle into the drum, but yes, it can happen if those seal are worn out. Dismantling that whole rear axle is a big job, unless you have done it before, or unless you have a helper who has experienced it, try to avoid that job. I hope this info might help you! Tom
