So I have posted in here b4 about how my car will "knock" or rumble at random interverals (about once every 3 seconds) in park or neutral (not drive) which vary in strength.
Now today b4 work I let the car warm up a minute while I had a smoke. I popped the hood just to take a look and I began seeing the engine actually shake (doesnt look to be to normal). I felt the dog bones and I could feel the exact rumble.
What does this sound like?
