Tie-rod Delimma
 

I have a 98 Cabrio. I went to do an alignment and, of course, the results were really bad. My tires were toe out about 7mm on each side. Then we went to remove the nut between the inner and outer tie-rod. It wouldn't budge because there is no thread to unscrew it. We heated, greased, and froze the thing and got nowhere with it. Instead, it's pretty rounded now. Any ideas on how to remove the nut? Thanks
