I bought it like this from the chevy dealership , I have no knowledge of what was put on , im just learning that the service manager says who ever installed the lift did it wrong and didn’t change the upper control arms and they said it has spacers and it may be the wrong angle on the ball joints , not sure yet what spacers was used , i am still finding out the details As of now chevy doesn’t want to help with costs to make it correct , I'm still trying to talk to them this is ridiculous@Aztb did you have a lift or level kit on your truck? What modifications had been done?
