To make it silent, take your time to read the installation instructions thoroughly as it has simply been pushed on too hard, causing too much friction between the cover and backing plate, we aim for a very slight gap between the components.
Please note that it's normal to have a little bit of noise in the beginning while things bed in. This will go away after the first ride.
Do not add any lubricant to lessen the noise. Lubricant will just gunk it up and attract contaminants.
