    Default My Dilema, F@#^!!!

    I had the "clunk" going in my truck, it was the u joints, the needle bearings were actually coming out of the joint!! Now the problem is one of the bolts at the rear of the driveshaft that held the straps over the u-joint has snapped off and all of the bolt was left inside, i have already drilled it and used an extractor and holy crap the extractor broke too. My last resort is to completely drill it out to the threads, re tap new threading and use a slightly larger diameter bolt, but will this throw off the balnce of the shaft and rear drive line or not. Please give some advice, I need this for vacation next week without it its a nogo

    Man what a conundrum you have there!! Puting in a slightly larger bolt will throw the balance off a little, but not enougt to ever cause a problem. If you are still worried about it just drill and tap the other side and all will be right with the world again, in balance Enjoy your vacation!!!! I wish I could take one

    That happened to me once except it was a bell housing bolt. I had just assembled the engine and I was tightening the bell housing bolts when one broke. Then the extractor broke and I thought I was up the creek. Loaded the engine in the van took it over to a welder who arc welded another bolt to the old one and after two tries out came the bolt!

    I'd guess that u-joint bolts are probably to small for this sort of thing, so I'd go with drilling the old one out. Use a sharp bit, and keep it lubed. You don't want to break off a drill bit and compound the problem.
