I'm not sure if I used the right terminology as I'm not sure what the part does, but somehow the bottom piece has broken and separated from the triangular top piece. When the car is running, the A/C pulley is nudging against this loose piece, making a feint grinding noise. It seems the inner piece is a soft, foamy/rubber type material. Is this just a noise dampening piece? If so, can I just remove the centre bolt and take it off, leaving the A/C pulley exposed?
I scheduled an appointment with the dealership on Monday to see if it can be replaced under warranty and inspect for any other potential damage to the belt or pulley system.
Thank you in advance for any input.
