So been having a weird noise come and go for a while now, ain't been able to figure out what it was till today. The crankshaft pulley seems to be wobbling quite a bit, and it's been getting worse over time (big suprise huh :P)
I was wondering if you guys would have any idea as to why this would happen, how to fix it? i bought a haynes manual today so i got the instructions on replacing the pulley and what not but what are the chances that the bolt just came loose or something and just needs tightening? any help would be greatly appreciated!

Thank you!

 

update acording to the diagram under the hood it's the vibration dampener pulley?

 

Yes the pulley IS the vibration damper. You need to try and discern if it's the outer part only wobbling or if the center is doing it too. Sometimes the rubber can fail and make the outer part move a little and wobble. The outside is pressed onto the center when they are made. DANGER...DO NOT pry on it if you take it off yourself. Use the puller. It's a low profile type. You'll probably have to take out the fans and some other things to have enough room.

 

ya got it figured out, all i had to do was jack it up on the right side and take the wheel/spash shield off and it's wide open to mess with. loaned the puller from oreily's and got the part for 59 bux : / expensive but a must before a long trip

 

well, got it off started to put new one on and the harmonic balancer installer didnt have the right size bolt, so i went and borrowed a pully installer instead and then i get the pully almost all the way on when it strips out the inside of my crankshaft....no idea what to do now.

 

I would have to see it to tell you what to do. Was the crank bolt easy to take out? Some shops won't touch something like that. You may have to call around a bit to find someone willing to try and fix it.

 

well had my mechanic come out and take a look at it he says it's fine lol. Not sure what stripped but whatever it was doesnt seem to be enough to keep teh bolt from going on. it goes on tight enough that i can spin the crank with it but there is about a 1/8 in gap still for the pully to go on. It is inlign with the belt though which is what he was looking for and he said that it's on all the way, but just incase to drive it for a week and then try tightening it some more becuase the pully might work it'self on more.

 

Update? Did the pulley stay in place? Did the noise go away?
