Does your truck lean to one side?

I’m not sure how they or if they wear either lol but I took the ones in question off and lined them up and didn’t see anything to indicate wear of any sort I would post a pic but we would all be looking at normal looking keys so I’m still just as puzzled ... just bought new ones and it sits level.

For using the level right in the center of the hood centered on the M if it’s a gmc and it’ll show you witch way you are leaning as well as jacking the rear end up and checking for light to show under what tire first as some one above stated.
