my truck is FIXED, finally. It's like I have a brand new truck, this has been driving me crazy for a year and a half. They did the TSB but the tech said he still heard something so they took my dash apart and found a rattle that they insulated.
I think this makes sense because even when my truck wasn't doing the "ticking" it still had another sound that was a little more subtle but bothered me so I guess both got addressed! This was Gengras in East Hartford CT they were great to deal with. The tech said he couldn't imagine living with a vehicle that made noise like that for so long
