I have a vibration at 70 MPH that doesn't go away after new, well balanced Michelin tires are mounted. It has 62000 miles on it. Any suggestions? Thanks, Joe.

I am having the same situation...right at 70 MPH and nearly the same mileage. Tried to troubleshoot it by giving it more throttle and letting off. Seems to be more evident while at a semi-coast. You seet his too Joe?

I have the exact same problem. I thought it was the tires but after I got new tires its still there.

I have the same problem. I bought new Michelins and went into the shop and we spun each rim to make sure they were true and then balanced in grams and the same problem still exists. It started at about 55K.

Hey People:
Exact same story - except I BOUGHT the car at 71,000, didn't drive it on the hiway til too late! Pretty dumb for a 58 year old guy. We've been through every hub, drive shaft and wheel. Must be in the transaxle, Buick says "well I'll be darn, what do you expect from our very best car, a smooth ride?"

hallelujah! The problem is an easy solve. GM website (perhaps exclusive to GM shops) suggests rear wheel toe-in off by 1/16 inch can cause tires to "warp" and vibrate. It took City Motors of Great Falls MT one hour and 60 bucks to fix it! Bennet Motors, where I bought the car refused to look further after 4 visits, wanted an extra $4,000 grand to trade for a car which booked for $2,000 less than my Park Avenue!!! They would have dumped it on the auction - buyer beware! Avoid Bennet Motors all there ads are just hype - I KNOW!!...dave

Oh gosh, I have a 2004 Buick Lesabre....sounds like the same problem. Began at around 30,000, now have 60,000 and went through 4 sets of tire, brakes, rotors done at least 2 - 3 times. It has been a ride from H_LL for the last 30,000 miles and Buick still says there is NOT a problem, and they can't find anything. HELP!! I spent $35,000 on a car I can't STAND to ride in.

1999 Buick Park ave. I seem to be having the same the problem as a few others the car has 26,000 miles on it. when you reach 70mph the car vibrates.
The worst problem and most dangerous is the car is stalling with no warning at anytime sitting still, moving and most exciting in the middle of turns !!!! Buick can not seem to find a reason why !! They have fixed ,changed , rearranged !!!!
whatever possible ... and tell me the car is fine ..........any suggestions PLEASE !!!! This is my final hope for this car or SHE'S HISTORY.

I have a 1998 Pontiac Bonneville with a similar (same?) problem. I can feel a front end vibration at 55mph and faster. Its related to the speed of the wheels. I run it up to speed on the rack and I can still feel it and see the front left wheel bouncing ever so slightly. I've tried new tires (all 4) new wheels, new wheel bearing, new axel half on the left side. Tie rods are tight. I cant put it into neutral and shut the motor off - no difference so I don't think its the motor mounts. I'm stumped.

Had the same problem with my 1998 Park Ave.
Fixed it by having the wheels balanced on the car.
That way the entire wheel assemblies (hub, brakes, etc.) get balanced.
However, the machine used predates the computerized wheel balancers now common.
Good luck in finding a shop that has the machine.

I took the advice of Dave - Stanford MT comments & had an alignment done on all 4 wheels 1999 Buick park ave.The service person said he had to slightly toe the rear wheel in & that eliminated the 68 mph vibration.He said the rear tires want to roll outward at a certain speed and that is what caused it. With slight toe-in they run true at the higher speed. I have spent the bucks chasing this problem over the past 9 years.
