It is as if something that is rotating has a rough or bad spot

Does the sound increase with vehicle speed?

Customer: replied 1 month ago.
it seems to. It's not very loud and you can't feel it very much.

Thanks for clarifying that.

If the noise is increasing with vehicle speed then we can likely rule out it being caused by suspension related components. It's more likely related to a rotational or drive component. That being the case and the fact that you already replaced the bearings leads me to believe it's highly likely that it's coming from the front driveshaft.

The easiest way yo find out is to just simply unbolt and remove the front driveshaft and see if it dissapears. If so you can replace the front driveshaft for around $180 i think it is.
