Are your lower control arms lowered all the way down?
Have you removed the upper control arm bump stops?
Have you disconnected the shocks?
If not you probably still have tension on the bars.
Have you removed the C-Clips at the rear of the bars on the trans. crossmember?
In the past I have done all of the above and one still would not come out.
I then took the strut rod loose, took the nut off the lower control arm pivot and smacked the arm to move it backwards. That pushed the bar back and I was then able to remove it.
They can be a pain.
