8 1/4 bearing adjuster
I believe the hex and the diameter are the same for both 7.25 and 8.25 and the hex for later 8.25 where in some cases the diameter is larger depending on bearing size and application. I'm assuming this, as the tool I made when I rebuilt my 2001 Dodge Ram diff worked on the larger size bearing adjuster and recently the small adjuster as well.
I made the tool with a 40" long 1/2 pipe nipple, a 1/2 x 1 1/4 pipe bushing and some roll pins to hold it all together. I trimmed the one end to fit flush and extended a roll pin just enough to clear the axel bearing and just long enough to keep it from going into far. I set the other end up the same way so I could turn it easily with a big aCrescent wrench, pipe wrench or my big ChannelLock pliers which is actually much easier than the wrenches. I actually have a big socket that fits when it comes time torque it down at the end.
