Question
Why would my pulley woble

Answer
Bill,

Is it the pulley or the harmonic balancer?  If is is just the pulley it could have been bent when someone worked on it or even from a wreck.  Now, there are other things that can cause this like a broken crankshaft or the rubber in the harmonic balancer rotting away.  I do not know the year of your Frontier or how many miles you have.  You can email me and we can go from there if you need more.  But, if the pulley comes off or the harmonic balancer comes off you are looking at a much more expensive correction rather than just correcting it now.
