Default A/C compressor noise

Just had a new 4.0 engine installed in my 2003 Ranger but now,
I have a squeal that is coming from the a/c compressor. When the clutch clicks and starts moving the squeal goes away. When the clutch free wheels it squeals!
Most people have the squealing problem when the clutch engages, not when it free wheels..
Do you think the clutch is going out on the compressor?

It is not worth rebuilding the compressor. Just buy a new re-man one with a warrenty. I had the same problem, and i just replaced it. Also if you have any salvage yards similar to mine, you can buy a used one for $30, your pick of compressor.

Why would you replace the AC compressor when it isn't the compressor that is squealing???

I just thought it weird that it squeals only when the clutch free wheels instead of like most people when the compressor kicks in.

I figured they wanted way to much for the parts needed to rebuild the compressor, and the possibility for a special tool which also costs money, plus the time you save yourself. I choose to simply buy a new 1, installed it quick, and moved on, problem solved. Then you also have the peace of mind that everything in the compressor is fresh and new and you don't have to wait for the next thing to go wrong.

New update:
Since I had the brand new motor installed last week, a friend told me all it takes is the mechanic to touch a pulley with greasy hands and that could make the belt squeal.
I bought a new serpentine belt and a can of brake cleaner. Cleaned off all the pulleys and put the new belt on. Fixed my squeal. $35 fix instead of $185 for a new compressor...
