I'm surprised how little dealers know about the TSBs. Thanks to Klaus where more knowledgeable then they are in some ways. You usually talk to some 'service advisor'. They're ones that come back with the generic answers like "well, what do you expect from a big truck?". I once a had a problem with my WJ where I had some unexpected vibration while driving. The standard "well, it's a jeep so don't expect it to ride like a Cadillac" answer was given. After pushing them to look at it they did find a problem.

Anwyay - I would say YES it's worth getting the TSB applies for the pinging sound. I does substantially reduce the sounds to normal levels.
