SOURCE: craftman 42 inch mower slings deck belt everytime
MOST OF WHAT YOU SAID IS CORRECT.NORMALY WHEN YOUR BELT STARTS DOING THAT YOU SHOULD REPLACE BOTH YOUR DECK SPINDLES AS THERE IS NO ZERK FITTING TO ADD GREASE.THIS HAPPENED TO ME A FEW YEARS BACK.HOPE THIS HELPED
SOURCE: How do I remove the spindle from the deck of a Craftsman mower.
Put your blade back on so you will have some backup on the nut. Wedge a piece of 2x4 between the blade and deck to hold the shaft while you take off the nut. You should do that before unbolting the spindle. If you are just replacing bearings, you don't have to unbolt the spindle at all. Just remove the pulley on top and the shaft with blade attached will slide out the bottom. The botton bearing, however, will be on the shaft and is difficult to get off. I use a bearing splitter to get it down far enough to drive off the shaft.

Is that how your manual recommends changing the belt?
On most riding mowers, the deck must be lowered in order to replace the belt
SOURCE: need to remove pulley from spindle to replace
If you do not the facilities to use an impact wrench, you will need to find to hold the pulley and you a breaker bar with a socket on it to get the pulley nut loose. I would use either"PB Blaster or Deep Creep" penetrating oil and spray it on the nut before you try to take it apart.
Or you may find a professional shop, take the deck to them and may may take the pulley off for a small fee.

You say you checked everything. I would remove the deck and belt and physically make sure both blades spin freely. Then I'd install the belt and check again, it sounds as though each component works fine alone but when in conjunction with other parts something is binding. Good luck

I left fixya four years ago. I looked in my files for the XT250 service manual. No luck doing that. I looked online with little success, (unless I paid $30 and bought a manual). At this point I can't really help you other than to say to set the idle (pilot) screw to idle speed desired, then turn the air screw in /out to achieve the highest rpm at the initial pilot screw setting. Re-adjust idle speed to desired rpm and repeat the air screw adjustment. You must have looked long and hard to find me. Best wishes...
