my rear end sits closer to the right side of my truck its dropped 2/4, and it also vibs down the road dont know whats it is though i know for shure it not my u joints

 

so your tire is closer to your bedside on the right side? Did you just install the drop? check to see if everything is tight

 

yeah i put the lowering kit on my self every thing looks lined up but i know its not cause my rear end shakes the it lilke the rear end and tire sits closer to the right

 

check your u brackets to make sure they are in the same holes...if you know what i mean.

 

Check to see if your bed is even on the cab on both sides. Mine is a hare off centered but I guess when they put the bed back on after the Linex coating they didn't get it centered exactly??

 

My passenger side is lower than the drivers side too. It's because when you have a full tank of gas and a driver inside it will sit level. Mine is about 1/2" difference with an empty tank and no weight in the cab, but with about a 3/4 full tank and me sitting in it it's level.
