I had been having some very annoying body squeaks on my 2016 TG with 27K miles. I'd been under it and spray siliconed all the shock bushings, pan hard rod bushings and anything else I could get within range, with no luck. Not even a hint of change. As a last resort, I took it into Green Mount HD In O'Fallon, IL. The tech there pulled the right shock and greased up the shock bushings, but still the squeak persisted even with the shock off. He stuck his head in the trunk and further isolated the noise. He pulled up the trunk liner and found ALL 4 body mounting bolts hand tight; one being halfway out. Those bolts had never been touched by anyone since new and had ZERO locktite on them from the factory. The tech blue locktite'd and torqued all 4 bolts and put the TG back together. No squeaks. It cost me an hour's labor, but it was worth it. I do kick myself for not thinking of checking those bolts though. A lesson learned. Hope this will help somebody out there with a similar problem.
