vibration on highways

[Green Machine 95]

I know this was probably asked before, but when I drive over 60mph I get vibration, it usually happens on curves

Do 80. It goes away if you go even faster (seriously)

Nobody, at least that I've seen, have been able to point to any single suspension component that does it. They pretty much just made the suspension really tight, and when it starts loosening up with age/wear/potholes/deer/curb checks, you get a vibration.

Getting a road force balance on a Hunter GSP9700 is step one. It shouldn't cost any more than any other balance, just not all shops have them. Go to www.gsp9700.com to find who has them near you. This might even take care of a lot of your issue, as the frame is supposed to be sensitive to harmonic vibrations from the wheels.

Other possiblities that occur to me since you say you notice it on curves more:

The brake rotors on the 95 are undersized, which makes them more prone to warping. They made them bigger in 96, but that's not much consolation for us eh? Anyway, I know I can feel my warped rotors more in turns than on the straightaways.

Depending on how many miles you have, your bearings could be going bad. They likely won't cause any harm, since it comes as an assembly anyway so your not going to chew up a spindle or anything.

One last thing is if you get a rhymic noise in the turns to go with your vibration, but it goes away when you straighten out, it could be your cv joint(s). A mechanic can look at those easily enough if you take it somewhere for an oil change or something.

Sorry I at least don't have a sure fire answer. If I did I wouldn't have out up with it for the last 90,000 miles

mine did that because the tires were out of balance.

I had the same problem with my 98'. I put new wheels and tires on, and it took Discount Tire 3 times before they could get them to balance. It was because the idiots who had been doing the balancing were applying the weights without cleaning the surface first. Guess how long the weights stay on when applied to a dirty surface? Hope this helps.
