This may be a dumb question, but I'm gonna shoot anyways. Just bought a Dana 44 for my 76 Blazer that had the "C" turned for a better pinion angle. The person did this right next to the u bolts and just welded it back up. My question is shouldn't he have put a sleeve on the inside of the axle to help support the cut? A knowledgeable friend of mine told me that with 42's and 500 hp, this has a real good chance of breaking off because it was only welded. If anyone knows a site with pictures or just explaining that you need a sleeve, that would be awesome. Or, just your general knowledge. Also, I'm aware I need a dana 60, but that hasn't happened yet.
