In my first attempt at driveshaft overhaul, I found that it was difficult to get the new center bearing properly pressed into the new center bearing mount. (They come as separate pieces)

Trying to drive the bearing in with a hammer was futile. It just doesn't drive in like a grease seal might. It had a tendency to pop right back out. Next attempt was using a vice. That was better, but I had trouble pressing the bearing in straight.

So, the result was a bearing pressed in using a vice that was not perfectly straight. This resulted in driveshaft vibrations at just about all speeds except 65+.

I probably would have had better luck using 1/4" steel plate in the vice jaws to more evenly press the bearing in, but I didn't have the plate and was in too much of a hurry to get running again.

So, I'll be back to the driveshaft "drawing board" again soon. I hope to develop a DIY procedure for replacing the U-Joint, as mine is not smoothly operating. It has a wear "detent" in the center of one direction of movement.

I'm going to go ahead and invest in a shop press from Harbor Freight so I can do bearing and ball joints properly.
