US made Milwaukee dolly

[Escape08]

I'm giving up ...not just yet.

I'm changing the 2 dry rot 10" dolly wheels for the first time and it's tough as hell. Did everything what I saw on YT. Nothing worked. The lock nut is made of quality steel even my Dasco Pro chisels are no match. I drilled the lock nut, no match either. I sprayed it PB Blaster and pry it off with a pry bar, no match too. Then, I thought of torching it my Benzomatic but it is out of propane. Time is not on my side today, but hey the weather is nice out here in Houston
These are the tools I have

I have that same dolly. I have to air up the tires every time I use it which is rare. Given the fight it’s putting up with you, I’ll just leave it alone.

UPDATE:

After 3 attempts, I finally got both lock nuts off with the help of a punch & hammer. I worked it out by punching the lock nut to move in circular motion. I did it by clockwise & counter clockwise to loosen the grip. Once it got loosen, I sprayed PB Blaster and pulled it off via Vise Grip. It took 30 minutes for each wheel. It a shame I ended this way as the lock nuts were made of high quality steel. Just by looking at the YT videos it took only 5 minutes. I replaced the lock nuts with fuel line clips/clamps so that in the future it will be easy to change tires. The dolly is now good as new.

These tools are the ones I used:

Fuel Line Clip/Clamp installed. I hope these clamps will hold well as both clamps grips really good. I cleaned off the PB Blaster residue before installing the clamps.
