Question about ac compressor need help asap

[wnaplay1647545503]

Vehicle is a 02 bravada. At idle I can see the pulley or clutch on front of the ac compressor(SERPENTINE BELT ATTACHES) not really spinning but attempting to on its own. It will move a bit but not much. When I turn the ac on, its cold and this pulley will move. Could a bearing be going bad inside the pulley? If so, is it time to replace the compressor? Anyway to check it or clean it or any suggestions? It is making a gawd awful noise. Thanks

if its making a bearing noise you'll need to replace it, if its another noise its gonna need a new compressor, if its the bearing buy a new a/c compressor clutch set, it'll give you everything you'll need

So you can replace just the bearing? How hard is it to do? Require special tools?

You'll wind up buying a complete clutch (either new or reman) and it will have a new bearing in it. The clutch shaft on the compressors vary, but you will probably need a puller to remove the old one.

or you could get emry cloth in strips and sand the air gap between the pulley and the clutch to get rid of the rust thats more likely causing the noise.

I will try this. It hasnt been this loud since I replaced the clutch fan in an effort to fix it. Today it became crazy loud and just knocking like it was a diesel freightliner. Advance sells the bearing for $20 so dont know if that might be a way to go if this doesnt work.

I think you will need a puller to do the job... But if it does need a new bearing get it taken care of before you HAVE to buy a whole new compressor.

I cleaned it with an emry cloth but it didnt fix the problem. The noise is definately coming from the ac unit. I assume by leaving it, it will eventually just break.
