If the compressor itself is still good, replace the clutch assembly without removing the compressor lines, else it will be expensive when you have to recharge.

I did this on my Dakota years ago, swapping in a clutch assembly I got from a junkyard, after the idler bearings started squealing. I spent a little time walking around the JY spinning compressor pulleys till I found a nice smooth one. The only tools I remember using was a 3 or 2 jaw puller (harbor freight), snap ring pliers and two large flat head screwdrivers. The screwdrivers were used to lever off the clutch assembly in the JY. I think I jammed something into the pulley to stop it from spinning, so I could unbolt it. I didn't use/create any special tools for that. I don't have a press or any special equipment and it was still an easy job. I don't recall anything about air gap and didn't use any shims. I got the bearing onto the compressor by using a socket that matched the bearing's inner race and tapping it on with a mallet. I'm sure there are things I'm not remembering, but I was able to get it done in the driveway. There was beer involved. LOL

These videos were most helpful to me at the time. Hope they give you clarity.
