Low Speed (20-30mph) Vibration

[themandan40]

I've searched and couldn't find anything relevant to my problem. I am getting ready to drive this car 2700 miles cross country and would like to have it in tip-top shape before I leave. When I accelerate or decelerate the car will vibrate between 20-30mph. Its not severe its just like a subtle vibration. It has only started happening in the past 2 weeks. No high speed vibrations or anything like that. I have had 2 alignments done wondering if that was it but it wasn't. Any ideas? I start my journey next Friday...coming down to crunch time!

i have the same thing going on, but in my case I know my motor mounts and steering bushing are shot.

Beyond that idk. Maybe someone can help both of us out.

Have the tires balanced and rotated. If this does not solve the problem, your driveshaft U-joints/carrier bearing could be failing. Do you hear any humming or buzzing sounds at all?

Kind of hard to tell over the exhaust sound. I don't think so though. I just put on different tires/wheels and still have the same problem. Could it be tension rod bushings? I'm waiting for my new ones to come so I can replace them.
