As the topic states...I'm looking at replacing my harmonic balancer tomorrow. My car chewed up and spit out a serpentine belt...then did the same thing to a new one within the first mile. I noticed a very slight wobble on the harmonic balancer and also noticed that a piece of the lip that holds the serpentine belt in place is chipped off. It's the belt that wraps around the power steering, A/C, and idle.

Are there any tips or tricks I should know before going into this? Anything people that have experience with this can suggest?

Thanks.

EDIT: Does anyone know if any guides that at least take you partially through the process? I did a bunch of searches and really didn't find anything helpful.
 
Alright, I just got this harmonic balancer from autozone. Yes, I know it's cheap but its at least in one piece and not rusted.

Wish me luck! Any tips or tricks would be greatly appreciated!
 
Ok, well, its been replaced. So far it's not throwing any belts. Some of the shaking the car was doing in the 50-55mph range has disappeared but theres no telling what else was thrown off or for how long it was driven like that.

Here's to hoping there isn't any serious damage.

Shaking at higher speeds is often times suspension/tires. You may want to look at balancing/checking the tires, front end alignment and checking out suspension points (specifically any ball and socket). The rear suspension can also cause shaking.

If you start to throw belts again, the "usual suspect" is the tensioner located between the power steering pump and the ac condenser. Many people just take it off and run a different size belt (if that's the problem)

Ah yes, postive thinking :thumb:

I inspected my suspension last night and it definitely needs to be replaced....at least the shocks do...and the bushings. The right front shock absorber is leaking fluid.

The more I inspect this car, the more I realize that the people that had it before me didn't do anything routine on it...and definitely didnt take it to be serviced at the dealer. If they did, they sure didn't after the warranty ended. 90% of the probelms I'm finding is normal wear and tear.

The first owner of the car bought it in Indiana...and from the looks of it, they don't have inspections. If they do, its not very often. The tires look to be pretty new. They have a ton of tread on them and very little sign of use.

Also, the shaking seems to happen more often around that 60mph mark. When you get it upto 70 it seems fine.

My first priority is getting this catalytic converter replaced. I'm tired of this thing sounding like a damn lawn mower.

Indiana (as a state) has no emissions inspections. A couple oddball counties do, though.

This is pretty much a text-book example of the symptoms of a tire out of balance.
