Quote: I would run it without a shaft.Make a dummy plug out of an old yoke and a plate to keep it from backing out. Run the car at the rpm it vibrates and shift 2-3 a couple times.Remember not to hit park,just shut it off. What happened to the original front drum? Did the bushings and washers look ok? Hows the end play?
thats actaully a good idea there, the front drum was in bad shape and couldnt be reused, end play is all good
