1994 Buick Park Avenue Vibration


Tires and Wheels problem
1994 Buick Park Avenue 6 cyl Front Wheel Drive Automatic 125000 miles

Put four new tires on car, rear vibrates at 55mph. Had tires balanced three times, replaced one rim said to be a little warped and still at 55mph the rear shakes! Also had both rear tires replaced with other new ones just in case it was defective tires!

Do you
have the same problem?

Initially it sounds like you've done all the right things. I repaired a problem similiar to this years back. What it turned out being was that brakes were done. Drums were turned properly however they were not put back the exact same way that they were taken off. On the hubs there are holes - (this is consistant with rotors or drums) - where the rotor or drums sits will be a rust build up. When they are put back on in a different spot it creates an out of round situation. Take your drums or rotors off and put them back on where the holes line up. Now if your drums or rotors have not been off the vehicle the same holds true for your wheels butting up against the drum or rotor. This may be a simple case of cleaning your rims and making sure that you have a good rust free surface where they bolt up to the drum or rotor. Corrosion will build up and this can be a cause also.
Side note: check for rocks or mud on whatever turns. I.E. Drums rotors wheels - a ounce of weight that is not in balance is like a 10 lb sledge hammer hitting the ground at 55 MPH.
Side side note: You also may want to have your tires balanced on the vehicle. Not many places do it however some still do. You may have a rotor or drum or hub that is out of balance. Balancing your tires on the vehicle might overcome the manufacture defect or rust situation. Drums and rotors are actually balanced. Drums especially and sometimes they even have weights on them. If one has come off then you are out of balance
I hope this helps
