Help: Vehicle vibration from 20-27 mph
I have an '04 325i Sedan with 140k miles. For about 10 days the entire vehicle shakes/vibrates when accelerating in the range of 20mph to 27mph then stops. No vibrations before 20mph or after 27mph. Seems pretty violent, change in the center console makes noise.
Replaced the tires yesterday, took the vehicle for an alignment today, due to poor front bushings they couldn't do the alignment, but I will have those this weekend and take it back. Although they did say the vibration is not related to alignment.
So, the question is, what's the #1, #2, etc cause that I should try?
