Hello together, I have a question again and hope I didn’t miss anything in the forum. One of the roles that the belt runs over makes noises. That means she is shouting a little louder. I just suspect that the bearing is defective and the role has to be changed. My question is, what role is it and what does it all have to change for them? Is this just the role or does this drive something bigger? I have a picture attached, which role I mean. I ask you what work you need to do at Service C. My car indicates that this service will have to be carried out soon, but I would like to do the work myself. Thank you for your support.
