427stang,
I got the yoke changed on the differential. I was flabbergasted by how much torque it took to take off the nut. And, like you said, there wasn't any way in hell I was going to get it off with a impact wrench, much less having it still in the car. I finally got it off with a extension on my breaker bar and then I thought I'd break something first. The yoke more or less fell off without any trouble. I called Portland and questioned him about the torque I was going to use to put the nut back on. He said lean on it just like you did taking it off, so I did. When it was drawn up tight the bearing spun freely. When I got through leaning on it you could feel some resistance. I remember what you said about feeling the roller bearing and it's not like that at all. Put it back in and I'm ready to take the driveshaft over to Ft. Wayne and have the 1350 end put on it. I didn't replace the rubber O-ring on the pinion support, I looked at it real good and it looked fine. Thanks for helping me. Jim
