IMy car has a slight vibration and I though it might be the driveshaft since thats so common these cars. Anyways I went to look at my driveshaft and it looks stock except has a sticker on it that says:

AAM American Axle Manufacturing Three Rivers

I did a pretty extensive search on google and found that my driveshaft is from the AAM three rivers plant...anyways.....Is this a stock driveshaft? or a aftermarket replacement...? I've found info on the internet but it could still be a sub contracted OEM peace? I'am unknown

 

Stock. Mine's the same..

 

American Axle was once a division of GM that became independent, along with a bunch of others like Harrison Radiator, etc. GM is still their main customer, AFAIK. So, it's an out sourced OEM piece.

So are all the drivelines that have these "vibration problems" are they all AAM's products? My car seems to have the vibration problem, but it dosent seem to get worse with higher speeds, seems about the same, worst at around 65. I've been going down a hill before and turned off the motor, and it made absolutely no change at all, felt no different. So i'am sure its something w/the drivetrain. What else could it be? Does the "Vibration driveshaft problem" always get worse with speed?

 

Whats the cheapest aftermarket replacement?

 

An american axle division is in buffalo and Im assuming the one your talking about is located in or around pittsburgh.

A replacement would be a 1LE or LS1. Also Denny's driveshaft would be a good option.

 

Is there anyway to isolate it so that i know it is my driveshaft that is causing the problem?

Could alignment or anything do this? I recently had 4 new tires put on(Firestone SZ50 ep's) and balanced them all. And the problem was still there.

 

yup,
they are a lot like delphi and guide corp.

I have a few college buddies that work there

 

?????I know you guys have some advice on the vibration deal. Come on now!

 

If you have a steel driveshaft there is a good chance its it. Before I got my 1LE I couldnt go into 6th below 2000 RPM's without a vibration. With the 1LE there is now no vibration at all.

 

how much and where did you get the 1LE? I assume GM? What was the part # and the price? Also, is the LS1 driveshaft better or cheaper, is it just as good?

 

Here's some discussion on the subject. I found it with the search feature.

Swap your driveshaft with someone else's that doesn't vibrate, and see how it feels. It's an easy swap, as long as you know some other f-body folks.

Yeah, there's tons of things that could cause a driveline vibration - it's just that since a large percentage of the 93-7 f-bodies had these un-round driveshafts, it tends to be a good place to look. [disclaimer: don't sue me] Put your rear end up on jack stands, chock the front wheels, remove the rear wheels, and run the car up to speed. If the vibration is still there, it's not your wheels or alignment.

Does the driveline vibration thing always increase with speed?
My car seems to really start vibrating around 60-70 but dosent get worse the faster i go. Stays about the same really.
