vibration on my c3

[Cdn UFO]

ok at 100k I start a vibration and it gets worse the faster I go, Is it the rear end or the main drive shaft. I need help so pls tell me your thoughts. Thanks Randy

No matter how good it feels don’t go to fast, you wouldn’t want to give up your vibrator to the police

How old are your tires when was the last time they were balanced? If you keep the car in a lower gear does it vibrate at a specific rpm or just when you hit 100k+? When was the last time the u-joints got replaced? Main driveshaft would be rpm specific. I’d guess ½ shaft u-joints or maybe a belt shifted in the tire.

Randy you must always use the Assembly lubricant with the vibration.
Should solve the problem.

I would try the easy things first. If it just started doing it all of a sudden it sounds like a bad tire or an out of balance tire. Maybe a wheel weight fell off. Hit any pot holes in the last while, that'll do it.

tires need to be balance. Just did that on my nissan max, problem solved, i know its a vette but same thing.

Could be a bad tie-rod maybe. Had this happen on one of my cars in the past.
