center support driveshaft bearing.......

ok so my center bearing is shot not, all the rubber rotted away so i go to replace it, i have the 2 driveshafts disconected froiim eachother, and im having a hard time loose-a-ning the nut to take off the driveshaft tip thing to get at and replcae the bearing, only fquestion is is there any easy way or anything i should know about befroe going to much further.

ok so now ive got the center support bearing in place, i couldnt get the bracket off so i had to do some creative pounding on the lower half with a rubber mallet, then put the bearing in place then pound it back to look ok. its a little cold up here so i took a break but all i gotta do is reconnect the rear driveshaft to the front driveshaft. just a note to ppl who have to do this in the future, if you can take the bracket apart DO IT it makes it soooo much easier and make sure you clean out the groves in the bracket. (mine had the metal o ring from the old bearing still)

Make sure you mark the driveshaft so you can assemble it the same way it came apart, If the front is out of phase with the rear half you will get a vibration.

well that part i didnt know, so now exactly how do you put the driveshaft back in phase?
