Drive shaft parts help

Well, I finally got around to replacing the front u-joint and center support bearing,,, had a vibration around 30 mph,,, so now I have traded that vibration for a worse one @ 50 mph
I put a another new center support bearing in, put truck in 4th and watched it,,, seems like the splined end has a slight wobble near the end. Am I making sense?!
So, I was wondering, does anyone have an extra laying around they would like to sell?!
66 F100/LB/240 I6/T18 I am thinking the shaft wold be the same from one with an NP435?

When you replaced the bearing, did you also replace the U shaped rubber support? What does the slip yoke look like, is it badly scored (as usual)?

Zerk fitting on slip yoke, cork seal retains grease. Most people are unaware of this fitting, so it never gets lubed. Slip yoke scores, vibrates and howls like a stuck pig.

Two-piece driveshaft, which one do you want, driveshaft or rear coupling shaft? If you had the drive and/or coupling shaft standing up somewhere and it fell over, it's now out of balance.

D9TZ-4800-A .. Driveshaft Center Support Kit-Includes bearing, shims, brackets and rubber support / Available from Ford.

Extra front drive shaft, from transmission to center support bearing. Not sure if its the main drive shaft, what the exact name would be.
And yes I replaced the whole koot-n-kibbiddle, comes that way from NAPA,,, not sure if the old one was just worn out enough to absorb the wobble? But it does appear the the very end,, the 4" or so of splines goes up and down at the end, just ever so slightly. The splines and yoke I greased up pretty good, and they are in good shape,,, appearance wise.

I'd take it to a drive line shop and have it checked. Really hard to tell just visually.

Thanks Bill!! On the phone with them now!

Nope, was easy to see visually, dropped rear shaft, started, put in 2nd, watched end of shaft go up and down,,, always thought it was the u-joint and carrier bearing causing the problem.

Unhappy Wrong one :(

This is NOT the right one,,, boo hoo,,,
I need the first driveshaft, that is u-jointed to the trans. then goes to the carrier bearing, then has splines on the end after the carrier bearing,,, I talked to the guy at green sales,,, he "thought" that is what it was, but he apparently couldn't physically go look at it,,, now $160 later, I have the wrong one
Soooo,,, what would the right one be? It has U-joint on one end, splines on the other end, directly after the center support bearing.

I am wondering if that when you took your shaft out and worked on it, did you get it out of phase when you put it back together? Because it doesn't sound like it is to badly worn. It has to turned a certain way with the rear shaft for correct balance.

Nah,,, the splined end has a wobble to it,,, I can put it in 2nd and watch it go up and down, maybe 1/8" or less. I did re-phase it, going to try it the other way now, 180 and see it that calms it down a tad.

Did you measure the original before you bought this? Did Green Sales sell you the wrong driveshaft?

Well, the one in my 66 and this one are not the same... my transmission has a fixed yoke, which my u-joint connects to, then it goes to the carrier bearing, then splines,,, so either this one has been labeled/tagged wrong, or something else is amiss, not sure which. The one I received, looks like the rear drive shaft,,, female splined coupler & u-joint----shaft----u-joint. The two books I have looked in, yes, crappy chiltons, and another something I had show the front shaft as the "coupling shaft" u-joint---shaft---carrier bearing---splines
I will call Green sales in the A.M. see what we can do... I really wanted the guy to physically look at it before he shipped it, and I asked him to call me once he had it in his hands, however, I am guessing he is not connected to the shipping process at all, just the phone side of things.

Why not just go to a one piece drive shaft and eliminate the problem completely?

Length I am guessing,,, got to be 6'+ of drive line from tranny to rear end.

Bill, do you have the part # for the coupler shaft?
