Have you taken a look at the center of your steering wheel? Does it say Jeep? There’s your answer.
Lol, I just finally resolved my wobble that was contributed to by multiple components over time. The Drag Link’s rod end failed, then the track bar bushings were shot, and then my ball joints were toast. After fixing all those in that order it drives solid again.
So like the others have asked, where or how are you feeling the “shake” and do you usually work on your Jeep yourself or have a trusted shop take care of things?
