2000 Century 231 V6 Front right shakes on accelleration Sign In

This is a 2000 Buick Century with the 231 V6 engine with 114,000 miles on it.

Upon accelleration the right front seems as if it has a seriously out of round tire or horribly bent rim. It vibrates and shakes something awful. It's noticeable at all speeds but gets really bad from 45 MPH and up. It's horrible the faster it goes. The shake and vibration is only on accellerating.

I'm going to rotate the tires just to eliminate that possibility. But meantime...Any help or suggestions will make me a happy man.

Did you inspect the CV axle?

The CV and then the strut are next just after we rotate the tires. I've heard that a BAD strut would give the kind of simptoms we're experiencing.

Probably tomorrow we'll check the CV and strut and will report back.

No, a strut isn't going to act like that. A C/V would most likely only cause it when under acceleration. The main causes are tires and wheels or possibly even brake rotors but it would be much worse when braking at high speeds.

Yes, this problem is ONLY on acceleration. Coasting or braking is normal. The vibration gets progressively worse as speed increases. Just slight acceleration above 45 MPH feels as if the front end is coming off.

The CV boot is OK and there is no clicking or noise from sharp turns left, right, forward and backward.

How do YOU check a CV ?

No, the clicking is a symptom of a bad outer joint. Your symptom is typical of a bad inner joint.

The only way to check that is to take it out of the car and feel it for binding in and out when under twisting pressure and even then you may not feel it.

Replaced the CV and the problem was almost all gone. when they replaced the out-of-round tire, the problem was completely gone with the car running smoothly.

Thanks much for the help.
