Hi all, just joined this forum.
I have just bought a C32 AMG saloon.
I am a newbie to mercedes so bear with me! Lol

I have noticed abit of noise coming from I think is the supercharge pulley.
I am going to change the oil in the supercharger this week as I have no proof of it being change, more for piece of mind thank anything.
But I was looking into getting the pulley bearing changed. I have found this bearing on ebay but from the states, was wondering if anyone could advise me if it's the correct one?

And, are they easy to change??

I would check what is causing the noise first by removing the belt and spin things by had (assuming it is run off the belt)

Yes, it is belt driven.
Is it easy to take the belt off?
