Shaking !!!!

Recently bought a 2002.. and have started to notice a lot of vibration when I Get above 70.. that MEANS ALL THE TIME... Car has the OEM wheels.. about 19.5 K miles..

My first thoughts were tires/rims out of balance..?? Appears that there are QUIRCKS on the C5's.. gas gauge, column lock, etc.

Just wondering if anyone has suggestion on what to look at..

C6 just won Car of the Year on Autorox......... Now that Carmen Electra really knows cars !!!

thanks for you help..

Heres to smooth driving at 100 +

Outside of that, Could be suspension/frame related I guess.. Hope this helps.

You know what needs to be done. Alien everything up first. Make all the usual checks. It would be great if Electra came with a new C6!!!

I think Dr. Ron covered it pretty well. One additional piece of input for you is to verify the vibration isn't drive train related. One way to do this is drive at the speed you can clearly feel the vibration and then change gears at the same speed (say 4th to 5th or 5th to 6th) and see if the vibration changes. If it does, it is more likely associated with the drivetrain and hence engine rpm dependent vice speed dependent. If it doesn't change, it is likely a wheel/tire/wheel bearing problem and Dr. Ron pretty much covered that above. Pretty easy for a tire to lose a wheel weight or slide on the rim and become unbalanced.

I have never known a shaking symptom that was not related to wheel balance or a bent rim. If you've already checked the obvious, tire balance, then I'd look for bent rim. Usually you can feel which wheels the shaking is coming from.

You guys covered it. If it is a lost balance, just make sure the tech puts the balance on the inside of the rim. One of my future projects is to correct these eyesores.

Another idea I have used to locate a tire out of balance is to have someone else drive your car and get it up to the speed that the vibration is the worst and continue at that speed. You, in a separate car can follow, pass slowly looking at your left wheels then allow your Vette to slowly pass you while you look at the right wheels. If there is a serious problem you can definitely spot it this way. Good luck in locating your problem.
