Please help

can someone spin the black part of the supercharger pulley and tell me if they hear a noise as if it’s grinding. Please do this for me. My car is making loud noise from the pulley I think

If you are hearing grinding there is a good chance the rear bearings of the supercharger need to be replaced. Verify you have oil in the front of the supercharger as those bearings are in an oil bath. The rear bearings are just greased (which is why I advocate against a fixed pulley).

Here is an example:

Here's wishing you it is not the rear bearings. And especially not the front bearings.

Bearings aren't a big deal. Take your belt off before you trash the rotors.

can you show me diagram of pulleys on the E55amg. I want to tell you which one I see wobbling. It’s the one on the bottom right. All they way on bottom. I see it wobbling, it may not be the supercharger. Either way I hope it’s just a bolt coming loose.

What did he do other than the oil?

Unfortunately bolts don't really come loose unless incorrectly installed. Not my picture but this has all of them plus the extra below the supercharger from the belt wrap kit, ignore that.

I really hope it’s the ac compressor pulley, that’s what I’m thinking. My AC went out 2-3 weeks ago, compressor is toast. So I think the pulley is toast now?

On side of the road rn, pulley literally dropped while I’m driving I hear a *thud* pulled over instantly. Literally no one around me I pulled over as fast as I could. Driving 40 and I pull over try giving a little gas, I figured hey maybe it’s good. Lol I hear loud screech turns out pulley fell out of the bearing and is on the bottom. Just called father and waiting for triple A
