What do I need to do this correctly? My ac compressor locked up
Your COMPRESSOR locked-up?
Or your compressor pulley BEARING locked-up?
There's a potential difference in repair process. If the compressor locked-up, you will need to solvent-flush EVERYTHING, and replace the orifice tube and dryer, there will be shrapnel everywhere in the system.
If the bearing locked-up, you need (at minimum) a new bearing. No big deal. If the system held pressure, you wouldn't even need a re-charge. The issue would be whether the system held pressure.
Naturally, you'll need to leak-test every joint/seal, and all the individual parts. In general, there's more problem with the condenser leaking than the evaporator, but both are suspect until proven good.
Given a choice, I'd want a new orifice tube and dryer no matter what. That's based on the age of the truck. If the system wasn't holding pressure, I'd replace every O-ring on general principles.
I put a compressor, orifice tube, dryer,and O-ring kit into my Trailblazer. Every "special" tool I needed was available from the Loaner-Tool program at O'Reillys. Other parts stores have loaner-tools, too.
