This is very common and usually doesn't have anything to do with air in the lines.
The pumps start vibrating when it is coming up to pressure and the pex pipe starts hitting the wooden walls.
There is a kit to add a soft hose between the pump and the rigid pex pipe will help some but I put pipe insulation everywhere the pipes were touching wood and I put a piece of thick rubber under the pump to reduce the noise.
Very quiet now.
