Anyone know where to get a crank pulley(harmonic balancer) mine is wobbling so bad its making the belt slide off a rib on the pulley.

before i go about replacing this is there anything else that could possibly make the crank pulley(harmonic balancer) wobble so bad?

 

Yeah a bent crank can make that happen its very unlikely. With the age of your car its just the rubber in the balancer has lived its last days. Might as well upgrade to a better one like an ATI ratter or any other SFI approved balancer.

 

I have one from an '02 GT that I pulled at about 20K miles. It looks good and it's your for $25 plus actual shipping. As an added bonus, it still has a March piggyback underdrive crank pulley bolted to it (I can take the pulley off it you don't want it).
