Husqvarna TS 248G Clear Cut deck won't level

I have a TS248G with the Clear Cut Fabricated 48" deck that I just cannot get level.  It was fine last year when I put it away for the winter and this year the first cut, issues. I live roughly 45 miles north of Atlanta GA for climate reference.
 
The left side blade measures from front to back tips a 1/8" variance where-as the right side I am a little over a 1/2" variance. The left to right side deck measurements are similar in scope, level. 
 
I am fairly certain the deck has developed some sort-of sag or warp but I don't understand how or why. I've owned the mower since 2020 and it's been a good mower. I don't have kids, I have a relatively flat yard free or rocks, boulders, holes, and tree stumps. I've never stepped on the deck my wide doesn't mow and I've never lent it out to anyone.  My only obstacles are fence posts which are easy to stay clear of.
 
I've removed the deck from the tractor and inspected the linkages and nothing seems out of place or looks damaged. With the deck on my shop floor it does appear to be straight. The blades are level which indicates it's not a bent spindle.

What is a little interesting and hard to explain, the right (discharge) side of the deck feels like it's not structurally sound. I can lift that front side of the deck off the ground with relative ease while the same side back stays planted on the concrete. I cannot do that with the left side. When I think of this and how the deck is suspended from the 3-links, it seems like that might account for the variance I'm unable to adjust out. Some sort of metal fatigue causing the sagging/warping... ? But why or how all of a sudden? I feel like I'm crazy.
 
I have a local Husqvarna repair center I'm going to take it to but even when talking to the owner he said if the deck has warp/bend issues there's nothing he can do and will likely need to be replaced. I'll still have them take a look since they do this stuff for a living just to see what they find. 
 
Im not sure it matters much given what I've seen with the deck off the tractor but, the tires are inflated 12psi in the front, 10psi in the back.
 
Has anyone had or heard of something like this? Maybe I missed an adjustment outside of the 3 links. I've searched online and come up empty.
