This happens every time I turn right and uphill at the same time. It can be felt, not just heard. It's likea wornball joint, though as far as I know there is no such joint back there. The car is still under warranty, but would like to know whether anyone knows what this problem is, so I can save time (and frustration) at the dealer. BTW, it's not the spare tire or jack. Does it when they're removed.
Thanks for any help!
