I have a 1992 dodge dakota LE, 91k miles autor with OD, i have noticed that when im sitting still at a stop light when i ease off everything is fine, but when i get down on it a little too heavy, it feels like something shifted or moved back at the rear of the truck not a lot but enough to concern me, truck is driving and doing fine but i just havent figured this out, i checked the ujoints and the spring hangers but see nothing, anyone else ever had this experience. thanks guys for any help.
