I'm not sure.. I saw them wiggle my wheel up and down... I didn't take it to a chrysler dealership though, as I didn't want the fee just too look at it. Just a regular mechanic ( alignment shop) I asked them if I just needed bearings but they said that no I needed the hub too

that was the second opinion. First I took it to national tire and battery for an alignment and the guy said I needed camber kits, but the second guy said he didn't look thorougly....
