I own a 2001 Bonneville SE with 112,000 miles and have vibration and shuttering from right front end upon acceleration and also accelerating on right turns. Replaced driver wheel bearing, passenger side half axle and CV joint, and left front trans mount. Still have problem. Has any one else experienced this and found a fix? Please advise and thanks!

Try jacking up the front end and check for any play in the wheel. hold the 12 and 6 O clock and push pull, then the 3 and 9 and check for play. Also push pull the whole wheel and twist is. If you feel any play, trace it back to what'* causing it, bad bearing, ball joint, etc.

Seeing that most of the stuff that should be looked at has been replaced, I'm thinking worn suspension pieces also. How the right front strut? If the struts blown the only thing that will dampening the weight is the spring assembly and the struts just going to wobble up and down for most anything,

Dear Dan,

Thanks I already had my mechanic do this and thus the replacemnt of the driver side whell bearing and the half axle on the passnger side. Could it be any motor or transmission mounts? I looked at them as best I could and they look okay! Please advise and thanks for your help!

Dear Kevin,

Had the strut checked at Firestone and they said it was okay! Thanks!

Does the frequency or intensity vary with RPM or speed? Does it ever do it when NOT under acceleration? Try slightly dragging the brake while accelerating to see if anything changes. Is it possible its a transmission shudder before the shift?

It does it only on acceleration at any speed and shutters worse on right hand turns. I went to a transmission place and they told me to do the same thing he said it could be bad torque converter but when I applied the brakes while accelerating still had shaking and shutter. Also when I go over a bump while accelerating the shuttering is more pronounced!

Chris....I'm thinking now that motor and transmission mounts need to really be looked at and make sure that the engine cradle bolts are tight and torqued down.

Had the front rotors machined and new pads put on, so they are fine.

Thanks!
