Honda ATV mechanic question

[Grndchecker]

I have a 2008 Honda Rancher 420. It is manual shift and has a shifter for 2wd/4wd. No electronics.
This past weekend I noticed that when I put it in reverse, it felt like something in the front wheels or the back left was dragging. The back right wheel would spin on the ground. Flat ground, dry, no extra load except my FA. I keep it in 2wd 95% of the time. I only use it at home or at the deer lease. Never in deep water or mud, rarely over foot pegs.
Wondering if it's either brakes locked on one wheel, which I've checked, or gears in back because it only does this in 2wd.
Anyone have suggestions to what to check next?
And I had just gave it a good washing a few weeks ago, not with very high pressure. Should have left it dusty.

Solid axle in the back?

Yes. Drive shaft from motor to one gear box, but box for each wheel.

One bump

If it has IRS you could have a broken axle

The rear wheels can’t spin separately from each other the axle is solid.
Unless the splines on the axle are gone.

Thanks for your responses. That's what I'm leaning toward now.

Let's see. It only does it in reverse and 4wd. Put it on blocks and turn wheels by have.. you need to locate the problem corner. Sounds to me like a front axle problem. Start at the hub and work you way in.
