not really jumping it is smooth, just fights the steering wheel.The auto got like 90% on the front wheels until slipping. If your not slipping and your car is almost jumping when trying to take a turn then it seems like your centerdiff is binding(yes I know it don't have one but I lack the name for it, transfer clutch?)
just wondered if this was normal.
it may just be the feel since you said the front is doing 90% of the pulling.
