dana 44 inner axle seals?????

I'm rebuilding a dana 44 out of a 77 scout II to put in the rear of my cj7. The parts store (napa) had a listing for inner axle seals yet I never removed any. Also I have never rebuilt a rearend that had them. The axle bearings are usally lubed by rearend fluid. I did try the seals and they did not fit . so the question is should this rearend have inner axle seals??????

There should be inner axle seals. They ride just inboard of the axle bearings.

You can use them or not. I left them out for the reason you said. This can cause the axle to leak at the wheel quicker, since you will now only be relying on the single outer seal.

I would definitely recommend using them. When you do find the right size seals, it is a b%$&h to put them in. You can go online and find articles on how to make a homemade seal installer tool, but I found none of them to work. I ended up going to completeoffroad.com and purchasing a seal installer that works for the DANA 30, 44, and some others for about $80.

The seal is there for a reason and I would definitely not rebuild without using it. Do it right the first time.

Good luck.

Reviving this thread...
I just got my axles back from the machine shop and cleaned up the inside of my 1974 rear Dana 44 axle flanges to install the bearing races and axles. There they were...inner axle seals. They certainly did not seal against the axle shaft, so what are they there for? If the bearings are lubricated by gear oil, why have a seal there at all? If the seal is supposed to prevent gear oil from reaching the axle bearing, this means the axle bearings are lubricated by grease only. Or do these seals limit the sloshing of the gear oil back and forth in the axle tube, controlling oil flow to the axle bearing so that the oil has to reach a certain level to overtop the seal and flow by it?
I'm certainly confused by this design!

Some 44's have greased rear bearings and some have gear oil lubed. My Scout rear is gear oil lubed. I know some CJ's were grease lubed. Either way, just go with what they were stock and you'll be alright.
