Compressor making louder noise when air condition on and getting hotter

when I turn on my air conditioner on my truck air compressor is starting to make louder rotating noise and it gets hotter when the air conditioner is on when it is off it cools down and the noise stops now I was wondering I have a question is there any type of way to oil the compressor thatvit does rotates or do compressors just go out what am i looking at.1988 GMC 2500 High Sierra suburban

Your description indicates a failing compressor.
I think that is a R4 and they are a short life compressor. Do replace with a new one versus a rebuild as the rebuilds fail at an excessive rate on that model.
