no humming noise. feel it all over, but primarily in the steering wheel. don't notice the mirror vibrating. does not seem to increase with hitting the brakes. have not used the hunter machine, i guess that would be next choice....or should i replace my front rotors, i know they are a bit warped.
the key symptom, i would say, is that the vibrations seem to go in and out, in and out, in and out...in succession
its a 1998 w/ 145K on it
Tell me a little bit more about the symptoms and characteristics of the vibration.....
Is it accompanied with a low humming noise?
Do you feel it in the seat, or steering wheel, or all over in general?
Does your rear view mirror vibrate quickly as well?
Does it increase when you hit the brakes at that speed?
Have you had the wheels balanced on the hunter machines?
Pertaining to the hunter system. I believe all the Just Tires stores have these units. YOU WANT THIS SYSTEM. It doesn't cost anymore than a normal balancing job, but the equipment used is far superior than anything else on the market. www.gsp9700.com will show you who in your area has the machine.
Most likely, it's probably just a tire out of balance. Or you have a warped brake rotor that needs to be turned.
What year is your car and how many miles are on it? What have you serviced on the car, suspension related? I'm asking because the rear carrier bushings are usually one of the 1st to go, and they can cause this as well.
