So I'm driving down the road and hear a series of thumps under the car. Looked in the mirror an notice a large black ring bouncing down the road behind me. Soon after that I notice the power steering doesn't work and the a/c feel like a blast furnace. Drive another 1/2 mile to the house and notice the outside ring of the crank pulley/harmonic balancer has seperated.

My question is: will a balancer from a 4.6 mustang work on my '97 4.6 bird??

that last thing you want is a lighter damper.

isn't dampener unit have the weight to cancel out harmonic vibration?

wouldn't a too light of a damper will move the harmonic frequency lower which will be in the useful rpm range?

am i making sense or just smoking too much?

I'm going to go w/ the Autozone piece. I don't have the cash to drop on a lightened one, plus it looks like the jury is still out on weather or not they are worth it.

Is there anything else I need to worry about while doing the swap??

Thanx for the help guys!!

I had bad luck with autozone getting a replacement, make sure the one your getting only has 3 arms like a peace sign and has a 6 rib pulley... they tried to sellme one with 4 arms and no pulley.... thats why I went to checker.

when you change it, pull the fan shroud and you should have enough room to get the balancer puller tool in there, thats what i did.... no need to pull the whole radiator

so is it a good thing or a bad thing?
bad. would you rather have a slight vibration at low speed, or a more violent one at high speed?
