Having problems trying to find a locker for it.
Two questions; what is it, how to change it.
How to tell between a h052 and a h072? Sold to me as a 3/4 ton
truck, but armchair mechanics have told me it might be a 1-ton.
The VIN is for a 3/4 but the arguments are pretty strong. Seems
to be it has had some modifications to it. Lot's of trouble
determining brake drums, then more trouble finding a universal
for the drive shaft. The Tractech folks told me it is a h072
after seeing these pictures.
Whatever it is I will probably, not sure yet, swap it with a Dana
60. Never did this before and would like to avoid surprises.
Where/what is a good source of instructions for swapping a rear
axle. Maybe I should replace the springs while I am at it? Help
me avoid surprises or having a project that takes forever.
It has two sets of numbers on the case
front view, drivers side top C-31256
front view, drivers side bottom 44-5F
It has one set of numbers on the case
front view drivers side 3934635 but it
is not clear, it may be S931635
It might be an Eaton h072 1-ton
It should be an Eaton h052 3/4-ton

All ideas appreciated.
