Im trying to take the castle nut off the pitman arm but it just spins with the stud. I tried prying but still wont separate. Thinking of buying a electric impact gun to see if it works. Any advice would be appreciated.

 

is the stud turning with the nut? are you replacing the putman arm?

 

Yes the stud is spinning with the nut. I am replacing the steering gearbox and pitman arm. I dont have a angle grinder, but am gonna buy a impact gun tomorow and pray it works. If I did have an angle grinder it would be hard to get it in there. Im trying to keep the steering gearbox in until im ready to pull everything out.

 

 

you might be able to go the parts store and rent a nut buster

 

I had same problem on a bmw once and messed with it for a long time before I found there was a hex socket in end of the threaded shaft. No clue if GM did same (would bet not as it adds cost) - but easy to check.
