Wheels spinning when turn.

Differential issue??

 

Put your power divider in and leave it in

 

I had a dump truck do that. I could see the tires turning backwards while I was going forward

Good thing I was only driving that pig for a few miles.

 

Nope. You can go at any speed with the power divider locked.
Important part is, never engage or disengage it, when the tires are spinning.
(Truck can be rolling, at any speed, but not "spinning")

The power divider simply locks the front drive axle to the rear drive axle.
One tire set (a "pair" on 1 side) of each axle will be "drive" tires then.

Add: Ideally, especially when your power divider is locked, you want as close to the same exact tire diameter for both the front drive axle and the rear drive axle tires.
I see that your rear drives are worn less than your front drives, which is typically not the case, unless they were swapped a while back.
The front drives "pivot" more during any turns (less wear), while the rear drives "scrub" more in turns (more wear).

But sounds like a differential problem you have. Are you sure the power divider ISN'T locked when this happens?

 

Pete, I made some adds & corrections in my post above, plz refresh to see.

 

Well, I'm still trying to get a grasp on what you're sensing/feeling on that right rear, and that part has me at a dead "Hmmm?"
Might see if the mods can move this thread over to the Garage section, in the appropriate model category.
At this point, you haven't said yet what model tractor you have.
I tried to give ya as much basic info as possible, but maybe someone in Garage can pinpoint the problem pronto?
