so i bout a new ranger bout a month ago. when i got it, there was no sway on it. i had no problems with it and i botu it with a four inch suspention and 3 in body lift. i just put on new 5 inch knuckles and havent done the back yet. but when i test drove it the truck did a death wobble at 45. almost flipped. Could this be from not haveing a sway bar?
