AC Compressor bearing

[GNERGY]

Mine squeaks when it is not engaged. On 91 burb. It isn't the idler or tensioner pullies or the alternator or waterpump all new. The AC compressor is a year old and genuine GM. Is it hard to change the bearing that lets the pully free spin? What special tools do I need?
Thanks

You need a clutch puller and installation tools. Also a good pair of snap ring pliers. Probably borrow from Auto Zone. Oh yeah, feeler gauges to set the clutch clearance.
