Rear control arms/differential shaft ?

[Jaybird91]

Hello im having trouble with my KJ rear end . Its doing the (hula) also i see as im driving my rear wheels are driving side to side . I didn't realize it was the bad until i noticed the side to side movement . Is it my lower control arms and differential shaft? how would I check each one? I replaced the UCA not to long ago but that was it.

So i lifted up the rear with my jack and put it on drive . Only the driver side wheel rotates and wobbles side to side . The right side passenger does not rotate unless i give it gas. Any suggestions?

Rear lower control arms will make it sway, like going up the road, give it gas it will pull one way, let off the gas suddenly it will go the other way
