Wouldnt that give me a constant vibe? Weird thing is, this vibe is sometimes hardly felt, at any speed. Then sure enough, there it is on the way to work in the morning and not on the way home,,,and vice-versa. Perhaps the bushing is bad and is moving around a little?

Oh, my exhaust system is very tight btw.

Sometimes when there is no or very little give, a vibration like you have occurs..

$200 for the new. I already have new yoke and ujoints. I'll pay to make any frustration go away.

Oh, the dshaft shop did the quick fix. They said my dshaft was modified at some point, i think shortened, the welds are different. Thus...new shaft.

I'm going to be completely frank here, have you had Vile drive it and feel this vibration to even determine if it's normal or not.

This is my last shot. Then i'll go crying to him if this doesnt do it. I have a gut feeling its the dshaft though.

I like to go as far as i can before i throw in the towel.  Lol

I would have started with him feeling it FIRST, then develop an repair approach.

Zieg mentioned my exhaust, i unhooked the rear and it seems better, it was tight to the cross member. Will keep testing. Unhooking front too. Stay tuned.

Dropped off dshaft this morning, turns out my original was modified and a little short, thus not sleeved far enough onto the tranny tailshaft. Plus the shaft itself is outta whack. Will post results of brand new shaft. And if thats not it, im dropping truck off at VZ's with a note and a pile of cash on the front seat. Lol

Brand new:
Driveshaft
Front yoke and bushing
U-joints

I can still feel a vibe down there. And i'm all out of ideas. At wits end!!! Now i need some help. I can no longer do or think of anything else.

Do you know anyone that you could borrow their tires and wheels to rule out a tire/rim issue?
