rolled under there yesterday, did not see anything obvious. No loose bolts, bent anything, etc. Lubed up the driveshafts, the U joints looked and felt ok, but I am not an expert. The vibration is mainly there from 30-45 MPH and the worst at 40, and only under power. I was going up a hill yesterday under relatively heavy throttle, and at 40 the vibration was bad. Let up on the gas and immediately the vibration went away...
