Well the axel shafts just pull out after you pull the Berring out but they are basically free floating. Hmmm you said you put new hubs in just curious the 3 washers did you put them in the right order when they were put back on also how bout the plastic thrust washer like all the internal did you reuse them. Just for giggles is jack up the front end and do a 12 and 6 test on both tires you say it is def both though right.

But there really isn't much on the drive line in the front un less you are grinding the gears on axel to the hogs head

Grease the front end see if that helps
