Kubota r530 tire skipping on turns

[Aidankozubal]

Hey there,
A customer of mine has an r530 that’s begun having some tire skip and shudder on low speed turns.
First thought was the lockers sticking on, wasn’t that. Check front and rear diffs, no cracked or broken teeth, spider gears still happy. Then I figured a bearing piled either in the drop box or finals, pulled both finals and drop box cover and come up with no issues.
The problem definitely seems to be coming from the back end of the machine, has anyone had this issue or any isnight into the matter?

Welcome to HEF, Aidan
Did you check the driveshaft while the loader is turning ?
Be super careful if you check it in motion.

Yes checked those, ujoints are good no flats spots in the needles. Shaft isn’t bent or dinged either

Any shiny spots on the U joint bolt heads ?
I have seen that happen once when the rear axle was not lined up correctly with the transmission.
