You are best off to get a rebuilt compressor. Other parts in the compressor are probably worn also so replace the whole unit. Most suppliers won't warranty a compressor unless you change the receiver dryer at the same the & flush the system.
Usually the shaft seal is installed from inside the compressor housing and is not serviceable. You would need to replace the compressor.
You are better off replacing entire compressor, then you know all other bearings and parts are good.
wheel bearings are going bad, need to change your hub assembly
Either the pump bearings are bad or the ac clutch is going bad. The clutch can be replaced but the pump bearings are not generally cost effective to change.
If you don't know how to do this then you don't have the right equipment to do it safely.
Check out the link below for a very good, detailed description with diagrams.
An AC compressor is part of an air conditioner which may be used in a car's AC system. The compressor is used to change the pressure between the AC's compartments in order to help condense the refrigerant gas back into a liquid.

How to change brake lines on a 1991 Buick Lesabre?
if you havent ever changed one before then you shouldn't mess with it, the freon inside the compressor is poisionest, it needs to be drained, new compressor installed, filled with dye to test for leaks, drained again and then re-fill with freon.
Could be the clutch is gone. If that is the problem, you can have just the clutch changed, but don't wait too long. If it is the bearing, then have to change the compressor. When it is running, you will see the clutch wobble. The clutch can be changed with the compressor on the car. There is room.
