To replace my Dana 70 I bought a single wheel one that was supposed to have come from a Chevy (the BOM doesn't lead me to any identifiable one). The more research I have done and the unique to Ford spindle nut leaves me thinking it's a Ford.
The question I have is on the threads. When taking off the stock spindle nuts one of them was really really hard to get off. It fought me the whole way and I noticed when I finally got it off there were about 2-3 threads on the end of the spindle that were messed up. My thoughts were to get a fine file and try to clean them up some or grind off the first couple of threads and not worry about it. I was wondering if anyone had ran into this before and knew any tricks.
