My A.C. compressor bearing is making some noise. I have ordered a new one. my question is. Is there a way to put some oil/grease on the bearings. It looks sealed but maybe someone has a trick so that I can run it for a few days.

 

They are sealed. Chances are the bearing will hold out until the new one gets there. Unless its screeching and smoking or something.

 

Turn the a/c off, this will disconnect it from the system.
