I appreciate all the replies. This is not a quick attach type of loader; I am not certain what "mounting plates" refers to (my tractor terminology knowledge is poor, my apologies). What drew my attention first is that the part called, in the manual, the "loader side frames" were not aligned. One is tilted corresponding to the cylinder that is extended vs the other. (If I understand the term correctly, loader side frame is the part of the loader sticking toward the operator that you maneuver into the frame of the tractor itself, hope I'm using the right term)
I don't appreciate any other twist or bend in the tubes holding the sides of the tractor together, but I'll get out there with a straightedge on Saturday.
If I can remove the snowblower (weather depending), I'll try to remount the loader and see if I can get more information, and maybe try the procedure from that video.
I'll post back when I learn more.

The mount that the loader connect to the tractor (the part that stays on the tractor) what I was referring to.
Those mounts bolt to the frame of the tractor and have some adjustment to them, you are supposed to check the torque for the loader mounts (where it attaches to the tractor frame) periodically as they can loosen, I've had it happen and had to re-adjust the loader mounts to everything to align again.
Have you used the loader hard lately? Such as using one side of the bucket to try and pry or ram something? It takes a lot to tweak the loader arms or torque tube.
Some pictures of the loader and tractor side mounts might be helpful.

My first engineering job out of university was in structures at JD Dubuque (yellow industrial stuff). One of my first assignments was to analyze the torque tube on a wheel loader (the boss made it sound like there was a problem... ha). So I wrote the work orders, had stress coat sprayed on the structure, ran the machine doing various load cycles (showed lots of stress (fractured stress coat) on the torque tube and welds), had strain gages laid in the hot areas, wired it for telemetry, and ran a full out stress test. The torque tube lit up like a Christmas tree!... very high stress. I was excited... "gonna solve this one!" Ha!
It was really just an exercise for me to learn the process of tractor design and testing structures. Boss zeroed in on the torque tube region because he knew it is one of the most active (high stress) parts of the structure. I'll never forget it either. The torque tube's only job is to maintain alignment between the loader booms. Any uneven loading on the bucket is carried by the torque tube. The boom cylinders are pressurized together in parallel.... only the loader structure keeps them lifting evenly. Hope this helps!
