I want to change my donor D60 pinion seal as a part of its refurbishment prior to swapping it in.

There is a .010" difference between 33mm and 1-5/16" socket but I'm betting on the 1-5/16" being the correct size. But that's not my problem at the moment...

I can't find a socket thin walled enough to fit inside the yoke. I picked up an impact socket (from Northern Tools) and it won't get in there at all. A "Martin" brand will get about almost half ways on before its outside diameter stops it from going in further.

This nut is to be torqued to about 230 ft/lbs, where do I find a socket that will fully engage the nut and stand up to this?

 

I took the Northern Tool socket back and found another socket but it is no thinner. Looks like I'll have to grind a little meat off the socket to get it fully engaged on the nut.
