What the heck is going on here?

I have no idea how to fix this. My BASE keeps jumping location when I attempt to delete the driver on the tread. All I do is press delete driver and BOOM, it jumps!..I reset the location to 0.0.0, and rotation on Z to 90. Then when I try to add another driver, it jumps again! I think I have something goin on b/c the location values are highlighted, but I have no idea what I could have done! PLEASE someone help!

SOLVED…!!! Animation somehow attached to object. Deleted animation and problem solved!
