There has been a slow refrigerant leak in the AC compressor for quite some time now. Late in the summer last year, when the AC was turned on, it would occasionally make a pretty loud growling noise. Shut the AC off, everything is fine.
Just this past week, the pulley on the AC compressor is making a worn bearing noise, while the AC is off. Turn the AC on, same loud growling as last year. The pulley looks slightly wobbley when running with or without the AC.
My question, is the pulley/bearing itself replaceable or do I need a new AC compressor?
Also it appear there was something splashed on the compressor but it is completely solid. Looks like a liquid but it is solidified. Not sure if that has anything to do with anything. (picture included) Thanks in advance!
You can replace the pulley assembly. First, though, you might try unbolting the compressor and getting some lube in there. Lubricant doesn't seem to reach the inner bearing races unless you can tilt the compressor on its back.

There is also still some refrigerant in it, so I am assuming I need to take that somewhere to be properly collected and then recharged after replacing parts.

Local shop wants just under $150 to remove than replace refrigerant after install. Common or high? I can't just fill it with cans right?
That is on par to evacuate and recharge the system. That also includes a vacuum test to check for any leaks in the AC system. I would definitely recommend taking it to a shop vs doing it yourself, they will refill the system with the proper amount of refrigerant by weight and ensure the system is leak free.

Shops do more than just refill they vacuum system down to negative atmosphere to make sure its not leaking. If you can vacuum system down it can be filled with cans.

Isnt that what I just said?

No problem. Most things I would say tackle yourself, but there are some things I leave to the pros with the specialized tooling to do the job properly.

Yeah that was pretty much the plan just wanted to double check. Honestly, I almost want them to do the whole job but at $300+ for parts alone, it's going to be an expensive job if I let them do it all.
I've done every other repair on this jeep but for some reason, just don't feel like doing this one. haha
