problem...need some help

i've got a problem with my truck, maybe someone could help me. i've noticed recently everytime i let off the gas, my truck's rear end shifts to the right. it only happens when i let off the gas and it straightens back out when i get back on the gas. (i mostly notice it when shifting)

anyways, any help would be greeeatly appreciated.

What kinda of bag setup do you have in the rear? Pics of it would help determine the prob.

yeah post pics. for starters could be worn bushings on link bars or leaf springs or loose ubolts or worn center pin hole on leafs or lowering blocks etc.

i'll get some pics up. i currently have 4" DJM drop blocks. i dunno if this would help but on the passenger side the drop block has chipped a piece off. but i'll get some pics up too.

do you get a clunking sound too? those blocks could be loose. retighten your u bolts and check the rear bushings for wear or if there is anything left to them........

as a matter of fact i do. usually when i let off the clutch to go i'll hear a "clunk" and it does the same when i put it in reverse. i'm gonna check the u-bolts tomorrow and give ya'll some feedback and pics if i get the chance and they turn out right.

good news. i did what ya'll suggested i do and checked the u-bolts and they were loose on the drivers side so i tightened them and drove it around, and no more rear end sway. thanks guys for the help.
