Add another wrench to your wrench to act as a breaker bar.
I tried putting the lug nut wrench through the closed wrench portion and use that to torque. I wasn't successful. Is that what you meant?
if it's moved but not more than a quarter turn are you absolutely certain you are trying to turn it the right direction?
/wouldn't be the first time
Is the issue with jacking the available headroom, or is it max extension on the jack? IF it's the latter get some lumber between jack and floor or jack and vehicle and get it done.
OR
A 1-1/2" or 2" pipe makes a good breaker / extension on a regular combo wrench and you can extend it as far as you have space for, to get more leverage.
Stop hammering.
I'm done hammering and heating. I've never understood how expanding the metal is going to loosen the bolt, but I'm Canadian, so what do I know. I'll go snag a 4in piece of 2in EMT after work and see if that gives a little extra leverage, I couldn't find anything that would work for a breaker bar at home yet. I'll have to couple that with some jacking up of the truck to give me room to make torque. That's bout the only other thing I could think of to try last night before I 'bout threw the shoulder out.
I some situations you can put a floor jack under the end of the wrench/breaker bar and pump up the jack to use the weight of the truck to help you.
I've used ratchet straps and chain binders to pull on wrench handles as well. I'm sure everyone has seen the 8 foot piece of pipe with the guy standing on it scenario. I typically don't recommend too long of a lever, but I've been known to pull off the jack handle a time or two.
I have also wasted a lot of time trying to turn the wrench the wrong way. Anybody who laughs at that hasn't been turning wrenches long enough to judge me.
Also, not all penetrating oils are the same. I've tried them all at one time or another. Some people think WD40 is a penetrating oil. People swear by Kroil penetrating oil if you are lucky enough to have a shop that sells it local. I've got some stuff called Loosey Goosey and it's a true penetrating lubricant and works in some situations. I have been in your shoes and tried a different brand penetrating lube after trying the usual stuff and the next day the bolt will seem to fall out.
I guess the bright side is you could always fully remove the cover and find an excuse to upgrade a part.
Good luck and don't give up. The world is full of tough nuts.
Just gotta crack it!!! I hadn't thought to use the jack to apply the pressure... that sounds like it might actually do the trick. Hopefully the wrench bites and holds well. I'm going to check at the hardware store for a 4point socket as well, may be that will be the key. I've warped the square head of the bolt a little, but not beyond repair. Good advice.

Then get a heavy duty cover that has fill & drain built in. Perfect time to get a Lube-Locker gasket as well.
Or you can find a Mac, Matco, Snap-on truck and get the correct square drive socket.

Or you can get "Same Day shipping" if you have amazon Prime, and want to buy $28 more "same day shipping" stuff...

I'm gonna look for a 4 point socket.. I know my 16mm wrench fits on the bolt, so hopefully they have them in that size. A new cover is what I'd love to have, look nice and fancy rolling down the road. EDIT: I see a cover and that gasket for 48 on amazon, and I happen to have a 65 dollar credit on my Amazon account.... if i don't get it open tonight, I'm getting a new cover and gasket.
If you have access to a welder get a nut that will slip over the square and weld it to the plug, then replace it with a socket head pipe plug.
A good idea, last resort option. Since I can't drive the vehicle till I get gear oil in there, I do have one friend who might be able to get his mobile welding truck from work and come by. I'd owe him lots of beer, me thinks.
Thanks guys. I'm gonna try a few of these things when I get home and I'll report on any success or failures.
