I know it is not a Explorer, but I own a 2000 Explorer that I have gotten tons of good help with and I recently had an issue with other vehicle, a 97 F150 so I thought I try here. Anyhow, I recently had the compressor fail on my F150 while on a trip. First blew hot air and got VERY noisy so I stopped using AC, then the clutch failed and bearings got noisy (clutch bearings had been little noisy, but here in FLA AC is on all the time so I let it go. Anyhow, I replaced the compressor in parking lot to get home then after got home I replaced accumulator/dryer and orifice tube. I blew flushing agent thru evap and condenser and lines. The new compressor said it came with proper amount of PAG 46 oil already in it and I drained the old accumulator. It had no oil in it so I added 1 oz. to new one. (thought rule was whatever you get out + 1oz. ) I evacuated the system for about 70 minutes (very humid in these parts so figured it had a ton of water in it). After I charged it the low pressure was 32-33psi and high was ~160lbs (I am not 100% of high pressure actually I forget). Air from vents on max cold was about 10 degree C at idle. Everything's fine for one day then low pressure hose from accumulator to evap blew off. I guess I didn't get the quick disconnect engaged properly. Clip installed and I felt/heard it click but????? Anyhow blew Freon and oil all over. I replaced o-rings and didn't know how much oil it blew out so I added 1.5oz. to system and vacuumed/recharged. Everything was back to way it was and blows cold. I noticed tonight after driving on highway and was 1/2 way home the compressor seemed noisy. Got home and listen to compressor at idle and was quiet again. Do you think it is low on oil? How do I know if it has too much or not enough oil?
I drove it two more days and I am not noticing any excessive compressor noises.... I think. I can hear it when it runs but not that loud and I am pretty worried about it so listen intently. They always make some noise right, it is a compressor after all. I realize over the net this is mostly worthless info. I also re-measured pressures tonight, 36 psi LS and 160-170 psi HS with box fan in front of condenser, 170 -175 psi w/o box fan, low side remained same with and without fan. All pressures were idling on max cool and 80 degrees ambient. I didn't put thermometer in ac duct , but air is still pretty nice and cold. I filled it using the pressures and quit when it hit about 33-34 PSI low side at idle. I almost used sticker, but it says 2lbs of Freon. I put QTY 3 of the small 12oz cans. If my math is right that should be 36 oz. right so if anything it is slightly over filled. My gauge set is sorta goofy and I purge a small purge when I replace a can though so I lost a very slight amount there.
Thoughts for any AC experts out there?

It also had what I believe to be the one way clutch failing in the transmission and I was sick of it. I only owned the truck for a year and that is a record for me, I typically enjoy working on things and learning and keep things until they are way worn out but this truck has been just terrible. I appreciate all the advice assistance I got/get from here and I still own a Explorer so i will still stay active.
