Ok...now my crankshaft pulley is messed up...I heard a noise comming from my pulley and sure enough it was wobbling around so I shut my car off and tightened it. Started her back up still had the noise. I pulled the pulley off my car and the thread on the inside of the pulley were worn off pretty bad. My question is "Is my Crankshaft ok?" I know my pulley needs replacing. My car is a 99 Ls so what yr. pulleys can I use that will match up. Any help you can provide will be greatly appreciated. Thanks!
