Ok, so I have had my Ford Motorsport aluminum driveshaft for a few months now but it has been so cold here I haven't wanted to install it. So this weekend, I put it up on jack stands and got under the car to see how bad it was going to be. It looks really easy to do, the only problem is I could not budge the four 12-point bolts attaching the stock driveshaft. Apparently they have thread locker on them from the factory. Plus, since they are 12-point, you can only fit a crescent wrench on there. Any suggestions? Would a 12-point socket attachment combined with an impact wrench get them off?
