Pinion nut socket size
 

I am planning on replacing my differential oil seal and need the socket size to take off the pinion nut so have it on hand. The manual says that this should be referred to a dealer but I did the crankshaft one so I am going to do it. I know that I have to mark the position of the nut relative to the shaft and count turns of the nut. Thinking of replacing the flex plates too as I will have the rear one off anyway. Ty

Hello - what year/model is this in reference to?
