hey new guy here with a problem out of no were it seems like my car started to shake like a left to right really fast shake ive checked my lugs all tight and some other stuff like wheel bearings and i cant find a problem. basically what it does is it will drive totally fine all the way up to 40 then it will shake until i hit 50 then it goes away. so its has a window were it does it in also it only shakes when im accelerating if i let off the gas it stops. this is driving me crazy it doesn’t effect my driving its just there. also my steering wheel doesn’t shake but it feels like its coming more from the front like were my knees are when im driving any help would be awesome thanks.

I would get them balanced. A wheel weight could have fallen off.

Balance tires first, then check for worn / loose suspension components.

Check your motor mounts also front and trans mount tend to wear out and do exactly what your describing.

My money is on tire balance. Keep us posted if you have the tires re-balanced and it is still doing this.
