Ohhhh ok....I feel like an idiot.
All this time I've been using a ratchet, not a "breaker bar". I kept thinking to myself, "Arnold Schwarznegger musta tightened this nut on". I mean, I'm a pretty strong guy, but nothing gave. Anyways, first thing in the morning I'll be heading over to Autozone/PepBoys to pick up the "breaker bar". I want to thank you guys for all your helpful advice. I dont think I should have a problem anymore--atleast I hope I wont. I will post again when finished. Again, much appreciated.
