Soundguy,
Tires are evenly worn, even measured the tread depth, within 1/32". Pressure is right where its supposed to be.
Hazmat,
I use 4wd for loader work mostly so I have braking power on the front. All other times I'm in 2wd. Lever moves easily when there is no tension on the system, which I can relieve either by changing direction or turning right and then left while under way. It always used to slide in and out of 4wd while moving with no effort. Its only lately that I've noticed the wind-up. It doesn't get so bad that I scuff tires (other than a sharp turn, which is normal), but it definitely winds up a lot of tension and it really pops when I take it out.
