Squeaky air conditioner compressor

I have a 1998 Expedition XLT 4x4 5.4L. I have a squeaking or squealing sound coming from the engine. After changing the idler and belt tension pulleys the squeal is still there. I now believe it is the A/C compressor. Does anyone have a quick and easy fix for it or do I have to replace it? Of course it looks like the most difficult accessory to get to and replace.

Thanks for the help in advance.

Belt

I believe the belt is relatively new. The engine was replaced replaced two years ago and currently has about 15K on it. The belt has no cracks on it and looks in good condition.

If it's the compressor pulley bearings, the noise will go away when you engage the compressor, since the pulley will now be turning along with the compressor shaft.

Check the condition of the rubber on the crankshaft pulley. If the rubber is deteriorated or coming out the outer ring might be slipping. They will squeal like a loose drive belt.
