Default Acceleration vibration

Hey all new question. I have noticed when accelerating around45-55mph that i feel a little virbration going on . I can't exactly pinpoint but obviously it is under the car. Is it possible control arm bushings? I had those replaced about 3 years ago. Again it's not a violent shaking or vibrating but I know how my car runs, and I know it's there.

Thanks Lynn

Could be as simple as tires needing balanced.

I would guess its the tires not being balanced as well. Just go have a place check if the rear wheels are balanced

Well at least you have a place to start. Even if thats not it , its not like you would be wasting your money at least.

If the tires were unbalanced, why would he feel it only while accelerating. Why wouldn't he feel it in that speed range all the time?

Mine does something similar first thing in the morning. I will get a bad vibration just like tires being out of balance. However later in the day, driving the same road and at the same speed, no vibration at all. The only thing I can think of is that the tires are flat spotting aafter sitting all night.

A loose object Resonating with the engine rpm, like the reserve tire frame?

A tire balance would make sense but then the vibrations would be heard or felt at almost any speed (between 20-90 mph).

If balancing doesnt do it, it could be one of the driveshafts. They do go bad and get unbalanced from a variety of causes. In the past, the fix was to use the Turbo ones, which I did...problem was fixed.
