I had to replace mine after one broke on a little outing.
I live in the rust belt so it was no walk in the park either.
When I tried to remove the rest of the end link from the sway bar it just ended up breaking off.
When I tried to remove it from the lower A-arm, I stripped the allen wrench and when I tired using the other sided with the nut, the boot cut ad leaked grease everywhere.
At that point I said screw it, took a hack saw and cut the damn thing off.
Now my wab-fab quick disconnects are in and I am set to go.
So my suggestion to you, do give yourself more of a headache and just cut the damn thing off.
