I had this happen last year (I think), bc it made the same sound on the front right suspension. I took it to the shop, and I think they said it was a rubber bushing that had rotted and broke in two and needed replaced. It was stock and never replaced. Jeep is 2010 JK Wrangler. Now, the same sound happening on the front left susp. but I would prefer to make the repair myself, if I knew what to do. (I will post audio of the sound, if requested.) Can anyone guide me? Thanks.
