Does your truck lean to one side?

Well Artic I have owned the truck for quite some time now and have done all the work on it as well and it is something to worry about when the side of the truck that is cranked many times more the driver side then the passenger side and it’s still sagging on the drivers side there is a problem so just cranking the key more isn’t going to fix anything ... I’m certain there’s an issue because like another said on this same post to jack her up and check the rear tires and it sure enough was off meaning there’s an issue in the front end problem is finding it ... I’m thinking replace the keys and go from there
