Q: vibration in front end through gas pedal on 2003 Buick Century

I have a 2003 Buick century with 68,000 miles on it. I recently had the right front wheel bearing and axle replaced because of hitting a pot hole. I am now feeling a front end vibration when I accelerate at a quick speed through the gas pedal and seat only. I do not feel it through the steering wheel. I have had the tires balanced and rotated and that helped some but it is still there. The front end was also re-aligned. I'm at a loss of what to check next. It has been suggested that it could be a broken motor mount. Any ideas?

I would check the motor and transmission mounts. You may also have a binding CV joint in the front axle.
Any luck fixing this problem. I have the same car as you 02 Century with 68K with the same problem.
I had it fixed last spring by a dealer. It turns out to be worn axle and housing. It did the trick. I had hit a bad pothole the winter before and I think that caused the problem.
