Question on 4WD mode on BX23

I know what you mean. My Jeep feels the same, I can tell when the front wheel hubs are locked just by the feeling in the steering wheel.
And now, when I started to drive a tractor too, I feel the 4x4 there also.

One more factor to add to the equation is that your tires are not manufactured the same standards as auto tires. They are probably a little out of round to start with.

When I ride my B7510 to the service station to get fuel I can see the rear tires "wobbling" back and forth.

Tractor tires are not balanced and at least on both Kubota's I have owned the way the wheel hubs are mounted to the axles the hubs may have a small amount of "wobble" in them. With a top speed of 10 MPH it's not that critical.

You do not have any suspension on a tractor either, no springs and shocks to dampen the wheel movement. The only way to change the ride quality on a tractor is to run more or less air pressure. When I picked up the B7510 the dealer had 44# of air in all of the tires and it nearly beat me to death on the 3 mile ride home. I dropped the pressure to about 25 in the rear and 20 in the front and it rides lots better and has better traction. They got that 44# idea because that is the maximum air pressure shown on the tire sidewalls.

But, I also own a Jeep Rubicon with mud tires on it so I am not used to a very smooth ride!

I just received my shop manual today, and got to see the front drive mechanism. A bunch of bevel drive gears, including one on the axle pinion. I think what I'm feeling in the steering is just NVH associated with all the front gears that are activated when in 4WD mode. It's very noticeable from 2WD mode, and I guess I just have to live with it.
