2001 Dodge Caravan 2.4L
The transmission was rebuilt. Soon after it I noticed grinding sound when accelerating between 45-55 mi/h. Went back to the shop but during the drive test there was no noise. I found the sound is weak and can be heard when the road is smooth and there are no noise from the traffic around.
I made a record of the noise. Any suggestion is appreciated.

 

It is a bearing type of sound. Was it there before the repairs? Does the sound change when you turn the steering wheel left or right? I would raise the vehicle and try isolate the sound on the lift.

 

This sound came after transmission was rebuilt. It is not connected with the turning of the steering wheel.

 

Is the transmission a 3 speed which I'm guessing or a 4 speed. But it sounds like a transfer gear bearing.
