What exactly do you mean by, "Go up the corner"? Can you be a little more specific? Also, can you fill out your SIG so that the members here can know more about the truck and if you have mods or not, etc...

You don't have a vacume booster.

Do you have any type of surging at idle?

up to the corner? (like to the stop sign and then off again?)
sound like a busted leaf spring or shock, maybe a mount causing it to rotate or "Bounce" under load.
I could be wrong though...
