When I start to accelerate, the car will start to shake around 2K RPM through 3K RPM. It can be visibly seen that the door panels shake. I've already changed out one of the wheel bearings, and both outer tie rods. It doesn't shake when cruising though, only on acceleration from that range. My last suspicion is motor mounts. It feels like it's only shaking when the car drones a bit from that acceleration range. The shake can also be felt through the steering wheel a bit too.
