I guess either I'm not comprehending what you & Timberhole are stating or I can't see the "Forest for the trees". So If I understand correctly 1 rear tire can have 5 psi & other rear tire can have 25 psi & if FEL is mounted squarely the bucket pivot pins will be the same height from ground or concrete slab. If that's what you're stating I'd have to witness this to believe it.

You missed it again.
The discussion is about straightening an FEL frame that is twisted. Has nothing to do with how the tractor is sitting.
Timberhole's method checks the FEL frame for twist. He's sighting across the FEL arms to see if they are parallel. To perform this diagnosis the FEL doesn't even need to be mounted on the tractor. It could be detached and sitting on the ground.
99.9% of the time an unlevel bucket is caused by the FEL arms not being parallel.
If you perform his sight test and the arms are parallel but the bucket still sits lower on one side when mounted on the tractor then tire pressure might have some relevance to compensate for problems elsewhere.

What you are trying to establish is whether the loader is twisted. If you raise the loader a couple of feet it allows you to sight across the top of the two loader arms to see if they are parallel. If it is twisted, they will not be parallel.
Try this. Lay two 4' levels on a work bench. Place the levels parallel to each other with about 1' between them. Place a 1/16" shim under the end of one 4' level. Stand back about 3 or 4 feet and move your head up and down until the top of the two levels come together. You will be able to see if the top of the levels are in the same plane. You are not checking for level, you are checking for twist. If the top of the two levels are in the same plane, there is no twist. Same thing applies to the arms on the tractor. You will be able to see 1/16" in 4 feet. If my math is correct that is less than 1/10th of one degree.
misalignment of the 2 mounting plates on my fel quick attach is something i've experienced too. in my case it was caused by one of my QA levers becoming released (unknowingly) thereby putting extra stress to the opposing arm when under load. as previously mentioned, the torsion bar then develops a twist resulting in fel arm misalignment.
i agree the textbook cure would be either torsion bar replacement or cut & weld back together as mentioned.
But this will not prevent another incident. Personally, i made adjustments raising & lowering the fel (under load) w/one of the sides unattached, the other secure. Solved the problem (for now) I'll let someone else describe that technique better than me.
my advice is to bungee down the fel release levers, & keep the load on the fel as centered as possible.
other? don't attempt a job on a B series intended for an M.
all in good fun
