I just saw a video on youtube where someone used a pickle fork (the one used to separate ball joints) and a big hammer to separate it from the frame - looked way too easy!

I agree also. I have a 5' long pry bar that can allow me to get in where i need to to go and get it to 'pop' free.

I have found that I will take out the bots but then thread them back in a about three threads so when the crossmember drops...it is being stopped so the angle of the crossmember is not putting the other side in a bind when I go to get it free.

I also used a bar which I bent but after a few days of wd 40 soaking and prying it finally popped. Leave bolts slightly secured so it doesnt come crashing down. Be patient it will pop

I just went at it again ,, no luck i have a 5 footer ,, I have a lift in the garage I might just strap it off to the floor and lift it just so i have pressure on it then go again

FOR WHAT IT IS WORTH:

YES..I have had some of these crossmembers that fought me to my last fighting breathe to get to release. So you are NOT alone on this.

What I noticed when I use my long pry bar is that if I do not get on the edge of the steel shell that is against the cone of the crossmember. When I pried down I could see that I was fighting against the rubber bushing and it was wanting to come own. SO .....

When I install my end of my pry bar I get on THAT EGDE of the steel shell of the bushing and pry against it so I am applying FORCE ON IT adn not just the entire crossmember causing the rubber to pull down and HOPE that it lets loose.

Keep in mind that that edge is thin and may take some time but when I do it that way on the crossmembers that just do not want to fall down...it has worked for me.

Which kind of confirms what I wrote in post #12 about the rubber being pulled on and stressed.

Good thing is that you can buy new bushings.
