shaking while accelerating

[G-118253]

2002 Buick LeSabre, trying to figure out a shake in the front end while accelerating between the speeds 30-50 after that it goes away. i dont feel the shaking in the steering wheel. when i let off gas the shake goes away also. i already tried rotating the tires and it did stop for about a week but came back. any ideas?

I’m having the same problem with my Buick regal I’m pretty sure it’s a motor mount only fill in throttle on acceleration under a load let off the throttle immediately goes away

I had the same problem, it was warped rear rotors, so I changed all four at the same time then the problem went away

If your rotors are so warped/have runout/cause your wheel to sit so janky you had some assembly issues but glad its fixed.

Maybe old ones and rust jacking

Just went through this on mine. Driver side axle shaft fixed mine. I also had a broken front motor mount.
