yep another one of these threads. just got my T about 2 months ago with 72k on it. noticed it had a small shudder under WOT. floored it off the line tonight and it seems like its getting worse. it only does it from 0-40, or if im rolling and smash into it. if i roll into it its fine. my rearend makes a slight wining noise from 50-60 mph but you can barely even hear it. the truck is on its 3rd rear end. so im curious to see if these trucks come with a 2 piece drive line cause it seems to me that the carrier bearing is going out. its an 05 king cab short bed. any help would be great. thanks!
