Woops sorry for the long delay. Thought I cleared all my PMs. The type of ball joints depends on your lift or if you have one or not. If you don't have a lift, go to your dealer to get them fixed under warranty provided your within the warranty period. If you do have a lift, you're looking at aftermarket upper control arms as your best bet. You theoretically could put in an OEM upper ball joint but you would just be delaying the inevitable.

what type of ball joints do you recommend?
