well I took a lot of pretty pictures but am having trouble getting them loaded here.  I'll figure it out though!  so whats happened so far is I pulled the passenger side axle shaft, the one that was leaking and had the fried bearing from brand-x, and tried to install the summers brothers axle.  The axle went in easy enough but there was about half of an inch of end play.  I hit myself in the head with a hammer about fifty times and then figured I should re-install the thrust block.  I did this and then the hub stuck out too far by about 1/4 inch.  I picked the hammer back up and have been pounding my forehead until I did a little reading and realized something.  To get correct endplay you need to install the passenger side first and then apply shims to get proper backspacing on the drivers side.  I still have the old brand-x shaft installed on the drivers side.  Doh!!  guess all that gear oil and brakleen have been saturating my grey matter.  going to pull the drivers side and attempt a proper install from square one.  I'll be taking lots of pics and  hope that the hammer will help me figure out how to post them.
