Hey “Pugtor”, did you ever find out what the problem was? I have the exact same symptoms after having my motor mounts replaced. My mechanic swore he used OEM mounts but prior to the repair there was no vibrations. Now it vibrates exactly like yours. Took it to a few shops but they can’t 100% guarantee it’s the motor mounts or not. They mentioned realigning the mounts but as that didn’t do much for you, just wondering if any progress was made with your vehicle.
