I'm searching for a vibration, and I would rather spend the time finding it, then take the truck to Ford. Anyone have any experience with chassis listening devices? Most I have seen have clamps that look like battery jumper cable clamps.

 

 

The vibration I am searching for is in the exhaust system, I think.

 

The chassis ears are nice but can be a pain. I used the wireless ones and kept having interference. They'll do the trick if you already know where you're looking though.
