I just finished replacing the transaxle on my 2011 MT Soul. The axles I only put a few hundred miles on before the transaxle swap. I had a differential with busted bearings and ended up methodically replacing every part of the drivetrain starting with the axles. Everthing seemed fine until i started smelling the obvious odor of transmission oil. It would usually come after running for a while. I got under the car to find my passenger side axle (the long one) leaking oil from the transmission. Is there a seal there? How hard is it to replace? I can't seem to find the part on rockauto. Thanks
