On spindles, I bought new spindles back in 2005 to replace mine (5 bolt hubs remember) and the standard ones did not fit. They were too tall once mounted in the spindle carriers and would have needed a custome made thick thrust bushing at the bottom to make them work. So we rebuilt/reused my old ones and took the new ones back. My theory is the older 5 bolt hub tractors had slightly different spindles and they only make them now for the 6 bolt versions. I also replaced hubs/wheel bearings at the time and the new 5 bolt hubs did not directly fit (A&I), had machine a few hundreds off the inside race to fit the dust covers in.

If it was me, I'd go to the new spindles if worn, 6 bolt hubs and be sure to get as heavy of front wheels as you can. They do make HD loader type front wheels just for that kind of applicaion. 7.50X16 sounds right for front tires.

While I was at it, you probably need to check and replace the front pivot bushing in the front end casting. Might need to rework/remachine the front pivot as well.
