rear dana 44 axle seal leaking...AGAIN!

Just like the title states, had a leak from passenger rear axle seal originally..replaced both sides seals and bearing pressed them on at my friends shop and now leaking again. I don't think my vent tube is restricted because I overfilled and it was spitting fluid last week. Any thoughts on what could be causing this to happen again? It's the same side that was originally leaking also.

I totally feel you. I've replaced my seals 2 times now in the last year, and it was still leaking. Recently, I tightened the bolts that hold the axle shafts in, and that seemed to stop the leak on my passenger side but not my driver's side. This past weekend, I removed the axle shafts again and put RTV around the seals, and then I tightened the bolts down as tight as I could (even tighter than before). I am hoping this will be enough to stop the leak, but it is too soon to tell.

I would rule out the axle seals being the problem, since you just replaced them and there is no way they already went bad. Don't be like me and spend $100 on new seals when the old ones are still fine. Did you put RTV around the seals when you installed them? If not, I would try that, and then tighten those 4 bolts that hold the axle shafts in as tight as possible.

Was the axle pitted or grooved where the seal rides? If so it will either need to have a speedy sleeve installed or the axle replaced.

I really couldn't see any grooves or pits. Was my first experience with this so I may have missed something. The seal is definitely shot and only thing I can think is I didn't press something correctly or that my shaft is bent. I work everyday so I've contacted a local 4x4 shop with tons of jeep experience and knowledge, and on Friday I'm going to take the shaft to them see what they say and go from there.

Now that everything is cut off I clearly see two grooves on sealing surface on both shafts..do you have experience with the speedi sleeve? Is this a good choice for a permanent fix?
