Thanks, guys.

Bodhi, one question about using the clamp. I'm thinking about how it would work. I feel like if I put a clamp on, it would attach to the area of the spindle right next to the stuck nut. With the clamp on, there won't be room to get to the nut with a ratchet. I'm picturing the clamp bolting onto right next to nut, where else would it clamp onto? If this is the case, how can I get the nut off?

If I don't get anywhere with the clamp and my buddy holding the spindle and the control arm together, I'll try the nut splitter. Diesel911, is the nut splitter just to break the nut off? And then I would need a new nut? Is that how it would work? Sounds promising.

Thanks again.
