I found pinion nut on the Dana 60 in my Demon loose at gateway msp, and the highway to St. Louis was backed all the to the race track so I just went to the Granite City Oreillys and rented a 33mm, same as a 1-5/16, for $10. It was a nice HD impact socket so I did not take it back, just kept it and put it in the trailer tool box.
