What Henry stated also.

If you do it this way....after you get it apart, throw it away. You have ruined it by rapidly heating then rapidly cooling, It will become brittle.

minitruck83 Try brake fluid. Tap it and let it soak in for 10 min or so.
Old junkyard trick.

Rob Keller PB Blaster is a good penetrator if you let it work for a few hours or days if you have the time.

Just as effective is wintergreen oil from your local pharmacy.

JPhil A technique I've often used on tough plumbing or boiler connections is to put a heavy metal backup mass such as a heavy hammer or piece of steel against one flat of the nut and then smack the opposing flat with a hammer. This has the effect of momentarily ovaling the nut by a few thousandths to break the rust bond on the threads. For plumbing unions, usually a pair of big pipe wrenches works. For smaller nuts, I use a couple of hammers but you may need to use metal block (such as a bodywork dolly) and a large punch to get an accurate sharp blow, which may necessitate the use of a third hand. I have gotten creative with bungee cords or duct tape when no help was available. It's important to have as full and accurate contact on the flats as you can or you may just deform the nut permanently, plus you don't want to miss and smash the exposed threads of the bolt.You may need to go around several times on adjacent flats, and use more PB Blaster. If nothing else, this helps the penetrating oil penetrate. Don't try to smash the nut, you want it to spring back to round.

Henry Highrise After I spray with PB Blaster...I use a 6 point socket and a impact wrench to vibrate it. If you use heat...do not put water on it, that will harden the nut or bolt and make it brittle and it might break on ya. If you heat it..let it cool a little then try to loosen it.

Stubborn nuts

If you are going to use a penetrating oil tap the bolt as you are spaying the oil and tap it again every few minutes while you wait. The oil seems to penetrate better when the bolt is vibrated.

58Chev I'd go for the heat also... Heat it up hit it with a hammer then a good long 4' bar on your socket wrench.

But if you don't have access tho these, a cut off wheel is your best friend..

Just did a lift on a jeep and was able to salvage half and cut half.

Rusty Nuts

Plenty of heat, and then squirt water on it. Repeat if necessary. This usually works good. It looks like this works best if this heat & water trick is done before any other chemicals are sprayed on to loosen the nut/bolt.

red65mustang a third vote for a cut off wheel or grinder.....only way 95% of the time

order new ones with the new bushings from any mustang resto house

pmeisel I would go right for the cut-off wheel. Those things rust solid down there.

Cebby I haven't tried it personally, but lots of folks swear by Coca-cola or Tabasco. PB Blaster is what I generally use...

ChevyTruckGuy Quit playing with it! cut it off and be done with it. If its that rusted your going to need to replace it anyway.

schnitz I'll agree with Sam, however I do need to add one thing. If you don't have access to a full-size torch (I don't either), I use a MAPP gas torch kit for the stubborn stuff. I works for me. But it does take a couple of extra O2 tanks to get the heat setting right.
