No doubt... I'm hoping it's something simple that I can fix/remedy! The way the SFR Engine and Transmission mounts are made I don't see how they could be transmitting that kind of NHV but it's there. I can't say for sure it's directly related to the mounts or to something else. I'm hoping it's a simple bind or something in the exhaust and hope to get it fixed. The main thing is that my rig runs great, I'm always busy and working... and when I do get free time it seems I get to work on my kids vehicles or do work around the house. You know the old saying that a mechanics vehicle is the one that's always broke, well that's how I feel most of the time.
