bad bushing?

yesterday i was driving from work and i noticed some weir play/clunking when the car was swaying from side to side a bit over snow and during turns. today it got worse, so i got under the car and with the help of my brother i pinpointed the thing that makes the noise. it is a metal bushing that connects that bar that goes along the rear axle. any idea what that bar is called?
its not the sway bar, thit is that thick square one.
and here is the bushing. any1 knows what its called or what the pn is?
here are the pix

Have you tried spraying WD40 all over the bushing?

Ya I didn't listen to the video. WD40 wouldn't help. That's the trackbar it looks like.

It is the Panhard bar or Track bar. You can replace it with suspension techniques bushings.

A track bar (also called panhard bar) is designed to keep the axle of your Jeep centered under your vehicle, so that you don’t have more sticking out the driver’s side than you do the passenger’s. To accomplish this, the track bar is connected to both the frame of the Jeep, and to the axle. There is a front track bar as well as a rear track bar (on TJ & JK models). See Pic

So, when you lift your Jeep, the distance from the axle to the frame of the Jeep grows, but since the trackbar is a fixed length two things happen:

- The axle is pulled farther over to the driver’s side of the Jeep
- The front of the vehicle is held down by the trackbar

This will create a good amount of wear on the trackbar, but more importantly, it will through your steering geometry off, usually creating bump steer.

i could not find aftermarket bushings for the trac bar of the KK, nor can i even find the OEM ones, looks like it only comes with the trackbar. not sure why but the mechanic did not see the issue until i told him to push the sidewall of the rear tire with his foot. that sure showed that that bushing is a goner and special ordered the whole bar, but since it was late friday evening, the order will only go through on monday and will arrive tues or thurs so i have to drive the car with that bad bushing for now.
