I have a 660 grizzly, a cvt.

Had the problem it wouldnt start in neutral, but solved it with a new sensor.

I do have a problem with the 4×4. When it’s engaged, the rear wheels don’t work.
The dash shows the 4×4 sign, i hear clicking from the relays and i hear some servo sounds from the front div.

If I noticed right, I do see some rotation from the connecting axl, can there be a problem in the rear div?
