k, I am restoring a 62 buick special that used to belong to my grandpa before he passed away. Anyways, I cannot get any of the lugnuts on the drivers side of the car to budge loose. I am using my electric impact gun and it certainly has enough torque. I just got done covering them in PB penetrating catalyst. Next to snapping off the studs andreplacing them, what other options do I have?

Thanx all!!

Just a thought, but are you trying both ways, they could be left hand thread......

I know Chrysler product cars had left hand threads on the left side of the car in the 60's. Not sure if any GM products did. You may want to look closely at the threads. You may be going the wrong way.

They are not left hand thread...................chances are, they are going to snap off. GM studs were only 7/16 and were prone to break, especially when overtightened. They are easy to replace.

A bit of heat on the nut will help....

Thanx BstMech, I went out and checked and sure enough. I flipped the switch on the impact and the first one came right off. I feel really dumb, I shoulda thought of that. Kudos to this site, this is what it's for. :thumbup:

I will go in both directions even if I was sure the studs were rt hand. I had a similiar problem on my Jeep that must have been used to put a boat trailer in the ocean the nuts were rusted on. Cranked up the air pressure to 125 and the soaking and all they came loose. Ed ke6bnl

Just one other trick to try...after soaking with rust buster take a hefty flat headed punch (I have a couple of punches that I have ground the heads flat on) and bonk all the way around the nut just slightly off center on each "flat" (but not far enough to the side that you will tear up the gripping edge). I had some stuck nuts on my F-150 that wouldn't budge with the impact gun until I had whacked on them for a bit with a punch and good size hammer.

On any coarse threads like a lug do let the PB Blaster soak overnight, it really helps.

Then if you can put a second nut (to protect the threads) on tight to the first and wack on that for awhile. Idea is to "crack" the rust.

And don't use a 5 lb hammer, it will warp the drums.

If they are really rusted on, better to get out a grinder and then buy and press some new studs (studs are not expensive, drums are)

Curious, was there a "L" or "R" stamped into the end of the stud... probably not....hate it when they do that

Good Olp PB Blaster!!

That stuff is great for getting through the rust buildup. You may sometimes need to let it sit overnight, even reapplying it and try it again in the morning.

yes, great tricks all. I was gonna let the PB sit overnight (heard somewhere that it takes awhile) and if that didn't work it was gonna be new studs. Thanx all!
