I have heard of a trick called heat shocking. You get the nut hot with a torch or whatever and then cool it off real quick with a shot of water. Supposedly the change causes the rust to break loose. Might try it one one to see if it works.

Also you could try a 50/50 mix of acetone and tranny fluid .I use this myself and it works good.

Thanks! How long do you let the 50/50 mix soak in? Over night

That would be a start. Of course there are other penetrating fluids available. but this is cheap.

Just curious if you had any luck with the nuts? I was rolling around under mine and looked at the bottom studs on my mine. Pretty crusty. 266,000 miles worth of MN. salted roads can make them pretty bad.
