Alright so here comes a story. I have noticed a clunk or thud of some sort letting off the throttle at about 60 mph. It gets worse the faster i go. Almost seems like i am hitting a bump whenever i go from half throttle to zero. if i ease my foot off the pedal it doesnt happen. Thought it was the slip yoke, so i pulled the driveshaft, lubed splines, checked u joints and trans mount. all seem fine. had both front wheel bearings done as there was wheel play when i had my driveshaft out. this is still happening. thought it was axle wrap, clamped springs and didnt help. so i got a mechanic to both ride with me and drive it. he says he cant feel anything and its normal. Is this just the torque of the truck and am i just losing my mind? I noticed a clunk leaving stop lights today. but that seems like the caliper and or the parking brake. this clunk is driving me up the wall, if its normal maybe i will calm down.

Male ssure your torsion bar bushings are not shot, might also make sure your trans crossmember is tight at the frame

now that you say the t bar bushings, i let my keys down for pulling and the one side i could move the bushing in frame with bolt out, and other side wouldnt move...
