LS-3 crank pully wobble.
My 09 LS-3 base doesn't show the wobble or chip with only 18kmiles on it, however just in case it does, I've been researching replacement possibilities, I've seen many videos on how to do it but not at my age so I had an epiphany. If the rubber between both of the metal components of the crank pulley is starting to crack, would a shot of WD-40 on the rubber stall or eliminate replacement of the pulley ? Just a thought.
Thanks

I think WD40 would accelerate deterioration of the rubber. Just don't do anything to it. Keep an eye on it and if and when it starts to wobble, then replace it with a good aftermarket unit.
