Factory Axle Stamp?
« on: March 28, 2022, 10:03:04 PM »
I was bead blasting my 12 bolt 4:10 rear end I had bought a few years ago and noticed grinding marks once the old paint was blasted off, it's not original to my car however I will be using it and just wondering if the factory did that?, are they original stampings?, also you can see the "E" stamped twice.

If it was a late build rear axle, then it might have been stamped originally CBV and the factory would have ground off the C

Haven’t seen a ground off C.  More like a peened C.

Same date as my BE rear.  That grinding looks like someone tried to clean off rust to read the stamp vs anything the factory might have done.  If the factory did it, it would be very intentional to eliminate worn numbers IMO
