A new Motorcraft pulley is about $80 from Rockauto. You're going to spend 5x (or more ) that if you have the compressor replaced. Unless there's an actual problem identified with the compressor, there's no need to open up the sealed system.
But hey, it's your money....

Do it from under the truck, the compressor is more readily accessible from down there. If you want even more room then remove the radiator. A couple of gallons of antifreeze is a lot less than having the A/C system recharged.

I have been looking around the internet trying to figure out how this goes together. Tell me if this sounds right.
1: Pull the Hub retaining bolt in the center.
2: Pull the AC clutch.
3: Pull the shims.
4: Pull the Snap ring.
5: Remove the AC clutch Pulley.
6: Put back together in reverse order.
7: Adjust air gap to .014 to .033in.
8: Tighten Hub retaing bolt to 9-10lb/ft with blue loc tite.
Does the AC Clutch pulley come with the bearing? My compressor doesn't turn on. Is that because my air gap is off?

You can buy just the bearing.
Connect a voltmeter to the 2 wires going to the compressor, if it shows 12 volts with the A/C system on then either the A/C clutch coil is bad or the air gap is too wide.
(See attached PDF.)

Just a note. If you are only replacing the pulley or are removing it to replace the pulley bearing, it can usually be done without removing the compressor from the vehicle. The shop manual procedure alloro posted is for the coil and pulley.

I have removed the AC Clutch and Spacer. I can't get the snap ring off. I might need to remove the radiator to give me enough room to work. I noticed some oil on the back edge of the pulley. Any idea what this means?

I can't get enough room to get the snap ring pliers in there. Anybody have any tips. I'm wondering if unbolting the compressor would get me the room I need. Removing the radiator looks like a pain. I don't know how the transmission coolant lines would come off.

I have tried both straight, 90 and 45 degree pliers. I can't get the snap ring off. I doesn't get enough clearance when when I have the pliers all the way open. I turn the pulley the snap ring gets covered up partially. I wondering if the worn bearing is making this near impossible.

I finally got the snap ring off. I had to remove the radiator and shroud. I was still difficult. I now have the pulley off. The coil looks pretty nasty. I'm not sure if I should replace it also. I'm not sure how I can add pics.

It looks like the bearing failure damaged my coil. I can see the copper wires have been mangled. I don't think they should be exposed by the looks of the replacement pics. Any tips on removing the coil? It doesn't look like there's much to grab onto with a puller.
