My truck has developed a shutter vibration in the driveline.. it mainly does it when you are coasting and pick the throttle back up.. I had the center support bearing replaced and i put new u joints in and nothing changed... THe convertor was going out so I replaced the transmission/convertor and it still does it.. I am beginning to think the shop put the wrong center bearing in it as they make different heights of them and it has the driveline out of wack.. I hate to go anywhere with it at the moment cause of this..

Not thinking it is the convertor since it has done it with 2 different transmissions/convertors with the last one being brand new.. It is more in the center toward rear part of truck

Had similar vibration in my 04 Duramax. Turns out it was the right rear wheel bearing.

fleming,I work at Indpls. Rack&Axle/Indy Driveshaft we see that all the time.You could be right about having the wrong carrier bearing put in.Also,is the D/S phased correctly?Could be a bad spot in the tube,out of balance or might be in the diff.

Driveshaft sticks on splines GM has special grease for this problem

Have that in my f150. I was a tech at a ford dealer and vibration on slight accell at 80 km was runout in the ring gear in the diff

I have it phased correctly i marked it prior to removing.. I am going to shim the bearing down 3/16" and see what that gets me.. The diff. is my next thing to look at.. very frustrating to find.. lol
