Wow, your Jeep is being covered under warranty. Isn't that what it is for? Let's start at the beginning. What is a radar box thingy, and how do you know it's the part making the vibration noise if it can't be replicated?
In a place where you are supposed to talk about Jeeps, and in this section ,specifically for warranty etc. He is getting his radar box thingy replaced under warranty. Maybe if you are having a rattle you too can get your thingy replaced, no one likes a noisy thingy.
But now that he has changed the text to "." I don't know what to think .
