My friend has a 1997 GST. It was having some vibration problems. I check the balance shaft and the tensioner was kind of loose. I fix that and the vibration went away. Now, he is telling me that after 65mph, the car start to vibrate. Something wierd is that there is almost no space between the bottom of the engine/transmission and the black frame support that goes from the bottom radiator support to the back of the engine maybe, maybe .25 inch separation. Well, I changed the broken side engine and front engine mounts, but still the same. The other two are in good condition and there still no space between the engine/transmission and the support.

Well, I for one have noticed that both cars I have, a '91 GSX and '92 Acura Vigor get the shakes between 65 and 70 MPH (and a bit higher) on the highway. There is noticable vibration at that speed in both cars, which I think is perfectly normal. I don't have the slightest clue as to your exact situation, but vibration at speed is normal as far as I know. No problems have arisen out of either car as a result of this vibrating.

Not particularly helpful I guess but it might just be simple harmless vibration.

It's running again shitheads.

Think for yourself. Question authority does not always mean disagree with authority.

I know him like 2 years now. Since he has the car I notice, yes, a little vibration. In November 2003, he was going to west Palm Beach and in I-95 he hit a bump. His slave line broke, don't know how. He was probably at 65-75mph. Could that hit cause the support to bend and to get the shaft balance so loose? Is there anyway that I can raise the engine/transmission from the support? Because with that vibration the engine/transm. hits the support and make noise. Also, the driver side rubber cushion in the middle of the axle is loose. You can turn the rubber over the axle.
Thanks

The cv joint doesn't make any noise in any direction. Looks like is fine. But I will try to make an extensive check on those. Anything else that I can check?

Thanks.

Well, there are a total of four CV joints. All of them look OK. The rubber I am talking is the one on the longer axle. This small rubber turns around the axle instaead of being fixed to the axle. Do you know which one I'm talking about?

Oh!, Thank you.

Every DSM I have ever been in vibrates at 65mph. Don't worry about it. My Talon does it, Matt's GSX does it, my roommate's Talon did it, etc. They all do it. My car did it on two different sets of wheels. 65mph is the magic number. It goes away after 70-75mph right?

I just came from a test drive! It is not as he told me. The vibration starts as soon as you step on the gas, hard acceleration. It is running great, but it is just that big vibration.It just a steady vibration. I felt it on the driver side. Also, the engine is resting on the support below. Is this like that on the GST's or there has to be a gap?

hmmm. now that you mention it, mine makes a weird noise around 50-60 ish. Not so much a vibration you can feel, but can be heard. Comes from the passenger side front end.

Wait, the engine is resting on the cross member? Look for broken engine mounts.
