The GMC CCKW

Yesterday I made my own tool to take off the inner nut for my rear wheels and while it fits and didn't break at all I can't budge the inner nuts at all. I think it may be because the truck was sitting 7-8 years before I got it,the tires are in so poor shape that I can't even drive it to my local tire shop to see what they say and my dad also thinks they will not have the tools to take off the nut as I also tried to fit an impact socket and it would not fit. I'm going to try one last thing using an impact wrench and if that doesn't work...... I have not planned that far really. I would like to know if there is a modern lug nut equivalent for the rear wheels that does away with the inner nut or do/should I just keep working at it with what I have?

Mr Dinosaur,

A couple of suggestions.

Budd style tools (sockets) are readily available on Ebay cheap to remove the outer nuts and inner nuts on the CCKW. A 3/4 inch socket on a bar with an 8 foot pipe as a persuader has worked in the past until I found a great deal on a 3/4 inch impact on Craigslist.

Put the penetrating oil to it to help loosen it up. Multiple times...

You aware that the nuts on the drivers side are reverse thread. I have been there and made that mistake

The "fire wrench" may have to be used to break the rust bond on the threads. Don't over do it. Several heat ups and cool downs can help. A budd socket on 3/4 inch impact while it is warm can help

I would continue to use the original configuration on the lug bolts/nuts. Loosening and re-tightening every few years will overcome the rust issue.

Good luck.

Oh God what a dumbass I am! I simply assumed that since the truck was 70 years old the inner lug nut would be some obsolete thing. That changes quite a bit of things and I have an odd feeling my local independent auto part store will have it,if not ebay. And yes I did know the front tires were reverse thread and thank God I have a tech manual or I would have done the same thing. Thanks very much Bill Wolf and I really deserve a Gibb slap for that one! [Big NCIS fan]

Bill's advise is good. Get on eof the combination impact sockets for Budd rims.

The thimbles (inner nut) and outer nust are the same ar the M-35 series trucks. If you absolutly can't get one looose and have to torch it off, I have some late model take off extra's. PM me

What good timing! I was actually able to get them off today. I bought a budd socket from my local auto parts store about a week and a half ago and I just bought a 1'' impact wrench and a 1/2 hose from my local Harbor freight today and while my compressor could barely keep up it popped those suckers off easy as pie! Thanks though.

With bigger trucks comes the need for bigger tools
BTW brand new 'nuts and thimbles" ( L&R ) can be pick-up at your local NAPA...although thier appearance is slightly different from the WW2 models.

Hope this helps

I think a 3/4;; wrench would have been enough but I used the issue as an excuse to get the 1'' because I have always wanted an impact that big.

I think my independent auto parts store has the thimbles and nuts too. I think all they need is a cleaning and they are good to go. I'm a bit worried though, I did strip one on the front and I'm not sure if it is fixable. My dad seems to think it is but I'm not sure.
