Removing Catylatic converters

What is the easiest way to bust the nuts loose on the studs to pull the cats?

Lots of pb blaster. Let it sit for an hour or so then add some more. 3 ft extension through the hood and a 15mm universal socket for the top passenger side nut. A lot of strength is needed to break them loose. Just be prepared. I though I was going to break my ratchet but they finally came loose. Good luck!


A couple more months and my license plate will say 1fstcpa!!!!

Lol. That works too! If you were in the Orlando area I would have just told you to bring it over. I have done this to two separate 5.0s now (including my own).

Yeah mine were incredibly hard to remove for a car as new as it is. They squeeked the whole way off. That is after pb blaster the day before and before removal.

Old school trick if heat isn't an option. Get in there and tighten the nuts a 1/4 turn. It breaks the thread interface and then 9 out of 10 will wind right off.

This from rebuilding turbo hot sides; I guarantee ther is no mor stuck nut on planet earth than those.

Another trick to add to the torch's effectiveness, have a hose or squirt bottle with water ready. Heat the sucker up hard slam water into it. This shock cooling often blows the rust right off.

Used 3 ft extension through the engine bay, with an impact and it came right off. Went back on the same way. Also using a swivel socket made it way
Easier to get the correct angle needed.

Yeah, I'd recommend a swivel socket. I didn't have one (nor did I have an impact), so I was only able to get the tip of the socket on the bolt.

Bolts

I soaked them anywhere from a few hours to over a day. I had the passenger side outer stud break, it went a 1/4 turn and just snapped.
We could punch the stud out, even with map gas heating it, so we ended up drilling it and welding a s/s nut to the back of it and using a s/s bolt.
Difficult to start but once it went it was fine. Put antisieze on everything, did n't want to risk breaking another stud.
