Hey BC928!,
I'm in the middle of putting new bearings in the rear diff of my 2011 E350. The one part that was scaring me was the seeming lack of a crush waster/sleeve. Your post gave me hope I hadn't "lost" it.
How did your repair end up going? I'm just about to start putting this thing back together. Any last minute advise for me?
I appreciate any help!
Thanks,
Steve
