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
- 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.
Pictures at:
REAR DIFF 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
