Trying to remobr a stuck castle nut. The cotter pin came out easily.
Nut does not appear to be rusted just tight. Suggestions to remove.
All ready sprayed with liquid wrench for 1 week.
 
Where is the castle nut? I would suggest a breaker bar in 1/2 drive if you have it. Some times you need to use an impact wrench to get them loose, if all else fails a gas wrench.
 
Can you try using a nut splitter? How about cutting the nut with a die grinder or dremel tool and cutting wheel. Where is the nut located? Posting a photo will provide better solutions.
 
Six sided socket. Sometimes a metric one is a little tighter (14mm on a 9/16" and 17mm on an 11/16")

Just get a good grip on it and undo it.

Is it irreplaceable if it breaks?

Try heating it first.

Mart.
 
Re: removing stuck castle nuts/ be patient

try an impact wrench just set to "rattle" or "chatter", as low a setting as you can get. You don't need to blast the nut loose, just rattle it a bit to get the motion going, sometimes even a second or 2 of tightening will bust the corrosion bond, then try to back the nut off. go slow
I have used 50/50 Acetone and ATF with good results. Give everything time to soak and you should be good.
 
Let me guess...it's threaded onto a ball stud on a drag link, or a tie rod end, and the stud is turning with the nut....? If so, as said above, try an impact wrench first. If that no-workie, disassemble the end of link and remove the stud. Get back to us. DD
 
I have drilled them in the low spots opposite each other, from the top of nut with a small 1/8", bit, then tap with a chisel and they will come apart.
Did this to some perch pin castle nuts, worked good.

These two castle nuts are on either side of the wishbone ball cap.
There are just bolts on the other side of the wishbone, right?
I ordered the Green Bible but have not recieved it yet.

It is not even turning, funny you would thing the nut work bw locked on the bolt and the entire thing would spin?
 
Everyone Thanks a million for all your suggestions. I could not have done it without all you guys. I owe you!
I will buy a impac wrench for future needs.
This is a pretty much original car from 1933 and I imagine that I will have need of it.
I was always afraid of schearing of the studs but I realized that most are just bolts and they can be replace if schreared off.
