Well, I broke an axle last night so I finished up my axle install then took the car out for a test drive. Ran great, pulled hard and was nice and smooth. No shakes. Get the car home and shut it off in the driveway. Clean up my tools and the garage and start the car to pull it in.. and its knocking.. Sounds like a flex plate to me, but I may be wrong. I replaced the flexplate last year with a low mile L67 one from a friend. What do you guys think? I got a video.
