well, you have to break the upper ball joint free so the lower arm drops even lower, then you can remove those two bolts at the back, move the teardrop thing forward off the splines, also make sure you remove the little bolt and nut at the front that goes thru to keep the TB from moving. Then if its a perfect world and all is right, the bar is pushed to the rear first, then it drops down and slides out towards the front.
But, if things are frozen in place you will be removing the whole lower arm assembly and finding a shop press to break the TB free. but thats a whole different can of worms
Also, be sure to mark the bars front and rear with paint, and or a punch or scribe so you know where they go upon re-install
OK, so I re-read your question, I missed your point, but no, the bar wont clear the front mount when the A-arm is low enough to release tension by coming out the front. SO, the tear drop thing has to be removed so the bar can then angle downward and come out under the A arm. I hope that makes sense.
I ended up removing the exhaust because even tho I could remove those bolts with a long extension I just couldnt get back in there to re-install.
