I tried to loosen the nut for the transverse arm mounting bolt in order to install the IPD rear sway bar and the bolt broke. I have new bolts, but I can't seem to get the old bolt out of the hole. I am able to turn it with a ratchet and it will unscrew about half an inch and then it stops and just spins. I tried to use a punch to get it out, but it doesn't move that way either. It doesn't seem as if the mounting holes are threaded, but maybe I am wrong? Anyone had this problem before? Could it just be corrosion due to the dissimilar metals in the transverse arm?
