Drive Shaft Phasing
I am in the process of changing drive shaft center support or (carrier bearing) well acualy rebuilding the complete rear drive shaft as I was putting witness marks on all the sections before removing anything I noticed that the frt. shaft between transfer case and ctr. bearing is not in phase as in the yokes are not alighed the yoke on the rear of this shaft (behind the ctr. bearing) is on a spline w/ a big nut holding it the frt. yoke is welded to the tube I was wondering if anyone has been here and found this before I am pretty sure but not positve this shaft has never been out of the truck I have always heard that the yokes needed to be in phase or inline w/ one another the truck has no vibration that I have noticed I am doing the RR to re-grease the slip yoke(shudder is getting worse) and the rubber around the ctr. bearing seems real loose if anyone has seen this on thier rig or know of a reason wye it would be this way I would really appreaciate the knowlege as always Thanks for any help you may have.

I suspect that your drive shaft HAS been out previously,, as your thought that the yokes should align is correct.
Re-install with everything phased in-sync, and let us know if it runs smoother.
You will note that the splines have one spline missing, but that is not to ensure re-alignment. It is to allow grease to pass out if there's too much grease to allow the spline to slide in as necessary.
Here's a decent page on the matter:

Thanks for the reply Pop I thought the yokes should be alined I guess it`s possible someone had it apart and mis-alined them I am going to try an get them in-line the thing is I have 3 new u-joints a new ctr. bearing and some of that xg-8 ford slip yoke grease going in w/ all this at once I would`nt know if getting them in-line is what made the difference hence there was no vibration before all this. Thanks again.
