Drivetrain vibration ~1500 RPMs
Hi there, new member with a question.
My 2000 C5 6-speed has an audible vibration/grinding noise at around 1500 RPMs during city driving. It only happens when the car is in motion, I can't reproduce the noise by revving the car at that level.
As a caveat, my harmonic balancer needs to be replaced and I'm waiting for one to be delivered (apparently they're on backorder). The bad balancer has caused a loud belt squeaking, but could it also be causing this vibration?
Thanks for your help,
jeff

I took my car to the Dealer on Tuesday Feb 10th, in need of a harmonic balancer replacement. As of today I still don't have my Corvette. The service manager is trying to locate one, but as of yet has Not. I am stuck in a POS 1997 Lumina for the time being. I have always wanted a Corvette, but this is getting old. Considering I called Autozone, and could have a new Dorman HB in my hand tomorrow, if I order it...

As you said the "vibration" only occurs when the car is in motion, I suspect the HB is NOT the source and may very well be drive-line related, i.e. drive shaft, rear axle(s), wheel hub bearings, etc.

Well - the part finally came in yesterday, exactly a month and a half after I ordered it. I'm going to limp over to the dealer to get it fixed under extended warranty. Thanks for your comments - I'll get them to check out that vibration too, but they'll probably say it's just normal...

I'm suffering the same type of vibration and I'm pretty sure it's the torque tube bushings or one of them from what I've read here on the forum...
I got a harmonic balancer that's been good for over a year and a half now off EBAY(stock size) for like $115 about a year ago and had it in 3 days...just for future reference cause I saw that post about "harmonic balancer backorder".

I've seen guys on here let them get REAL bad before replacing them...not to say it's not important but it's kind of a big job to pull the torque tube to swap em' and there's always confusion on which ones are the absolute correct replacement PN.
GM doesn't sell em' independently from what I've been told, there is a BMW torque tube bushing replacement that supposedly does work.
Some guys will also say run both solid and some will say run one solid in the front or one in the rear...
From the factory the car has "rubber/poly" bushings probably to keep vibration down.
I'd make it a point to replace em' depending on how bad your vibration is...I mean, you'll know if the bushing totally lets go but like I said they can get REALLY bad and the car still is totally "drivable".
