Default Rear end vibrabtion over bumps...

Yea, i got that exactly. I have a rear Detroit auto locker and a 2.5" TF lift. I notice that after i hit some bumps on the road, i get a vibration, almost like an "echo" of the initial bump. I know it's coming from the rear. I can also hear something rattling back there when i go slowly over some rough pavement. I've looked under and can't figure it out. It seems like it's a suspension issue, since other than hitting a bump, he's fine. I don't know if maybe it's a spring a tie rod end or something like that. If i grab the tire and rock it side to side, i can create the sound of something loose. But i can't find it and i don't know if its even related, cause i've heard this for awhile. but never had any issues with the ride of the jeep. I've never had any issues with the rear end of the jeep! Can you guys give me some suggestions on what to look for before i take it to the 4x4 shop? I can fix anything, i'm just clueless here....

check to make sure that your rear track bar bolts are tightend to 125 ft lbs of torque. if you have a relocation bracket, make sure that the mounting bolts for it are tight too.
