2005 SMB E350 rear diff question
I've got a little issue with the rear diff on my 2005 SMB 4X4. Not a full float, just the basic as it came from SMB West.
My mechanic found a bunch of metal shavings and nasty bits in the diff and would like to replace some things, but doesn't think it's the stock E350 diff.
Any thoughts, I did a search but couldn't find anything specific on the forum.
