I haven’t been able to find any topics on doing this job on a C6. I find my car makes quite a wicked drone when accelerating at about 3000rpm. How can I diagnose my mounts, and what would be involved in replacing them if I need to?
Okay. So need two folk for this. Put your ride in drive. Brake full. Give gas till you engine revs up. Have a body out beside your open hood. To listen for and clunks cleaks, and odd noises. Also they should watch the travel of your engine during this. And you should blow a few codes…these cars tell you everything.
