what the heck is wrong with my front end?

Very Common and they do it even STOCK.

Nothing to worry about

what i don't understand is why they only lean like that when i back up,when i drive straight and park straight,there fine.

I have never seen a lifted D50 that doesn't do that. Even in stock form they do it a little. You would have to classify it as normal but normal doesn't look very good. Only fix is a D60 upgrade.

You want to see something else that will bother you? Have someone drive your truck on a rough four lane road while you drive beside them. You will see the tires doing the same thing over every large bump.
