I think that may cover that then.....

Worn cv joints can cause vibrations at different speeds.

Thanks int, I am definitely replacing the CV axles, as I don't have many things left that could be causing a rotating vibration. I can see CV axles being worn from my driving style.

I had a worn cv axle on a ' 90 Lesabre.Steering wheel would have enough vibration starting at about 70 mph to numb my hand after awhile.The axle never made the usual clicking or knocking noises but did clunk sometimes when going into reverse when hot but not when cold when the idle was higher....go figure.It finally got replaced at around 140,000 miles due to torn boot and and dirt intrusion.The clunk and vibration went away.Woulda replaced it 30 or 40 k sooner had I known.

Helikon, that sounds exactly like the vibe I'm having -- the steering wheel will make my arm fall off from the shaking if I drive over 70 mph for any length of time. I'm doing CV'* tomorrow if I finish installing my new Muncie M20 4 speed trans in the Camaro tonight.

1997 Lesabre.....Just had an afterthought.While my car was on the lift getting that right front axle replaced the mechanic showed me the amount of slop in my ball joints.I couldn't believe it.So I had him replace them.Ain't no way in hell I was gonna try it due to lack of facilities and tools.That tightened up the front end and cured steering wander..The ball joints never seemed to give any problems except the tires wanted to follow "lines" or mild ruts in the road.I guess it wouldn't hurt to check yours while you're at it.My ball joint boots had been shot for tens of thousands of miles and I just greased them every 3000 miles.

Helikon, the car has 70k miles on it and has been very well kept (garaged, always waxed, always serviced immediately when a problem has come up). It looks and drives like a new car (with the exception of the vibration now). The ball joints should be fine with this mileage. The car has been lubed every 10k miles and all dust boots are completely intact. It is definitely a rotating imbalance -- I can feel every cycle of the revolution in the whole car, and in the steering. The vibration is even there at low speeds (30 mph), it'* just very minor then. If its not a CV axle or a front hub assembly, I'm out of options -- there isn't any thing else that rotates that hasn't been replaced. Even the transmission and torque converter have been changed now.

I had a 86 escort with 175,000 miles on it....still had the original ball joints...this is the most overprescribed item at alignment shops..

i think that even thou you have 70k it could also be the Ball joints

I know this thread is 2 years old, but I'm hoping that any of you found solutions to your vibrations... I have the same thing in my 98 Bonnie and I would LOVE to fix it.

Thanks,
