Seals and Studs

Thanks... I think you are onto the leaking pinion seal problem. I did not remove the pinion seal since it was not leaking when it was sitting full. I do not know the history of the axle before I got it; but I know it came from a junk yard and since it was off an 87 or 88, good chance it had just been sitting for a while. I did over fill the axle, I thought I was being smart by doing this since the axle was dry (tilted it from side to side to drain all the oil I could) and the extra would compensate for re-lubing into the axle ends... perhaps I put a bit too much in. I also used a synthetic gear oil which would further explain the leaking since the synthetic is thinner oil. Is it worth taking any out, or should I just let it drip for a bit and monitor it to see if it stops within a few weeks?
I also like your take on the lug nut studs. The axle has new studs that were installed prior to me purchasing. However I noticed that the stud backs are not flush with the hubs. I thought they were in enough since they are pressed in; and seemed tight enough. Probably not tight enough. Do I need specialty tools to finish pressing lug studs in all the way? Jeep does run smooth and does not seem to have any additional vibration other than the driveshaft. (tested by running down the highway for 30 miles.)
I was surprised that the driveshaft vibration does seem to be worse with the 44 than the 35 was especially since I added shims to correct a bit of the angle. I am pretty sure that the increase in vibration is from the driveshaft angle since the sound the driveshaft makes when I left off the gas at speed also got louder.
I must say that I have had as much fun learning and building this jeep as I do wheeling it. I did not expect that; but good thing since I put much more time in under the jeep than in the dirt... Thanks again for all the help.
