AC Compressor squeak v2
 

Hey everyone, haven’t posted here in a while. I’ve exhausted all options prior to coming here. The car is a 2001 Pontiac Formula. Got the A/C recharged last month due to a line being broken in the past. Everything was great until the next day when a squeak started coming from the AC Compressor. Validated it was indeed in that Accessory belt system by removing the AC belt. I’ve replaced the idler pulley and the teinsioner pulley (ACDelco 36220). I also replaced the A/C Compressor Bearing (SKF 5908VAW) and the A/C Compressor Clutch Disk while I was their also. (ACDelco 154685). Removal and install went smooth. However, the squeak still remains. When I spray WD-40 on the Compressor area it goes away for a few days. This makes me feel that the problem is external and not inside the compressor clutch. Any ideas from anyone at this point?!? It's going to be quite a bit of money to remove/replace the compressor.

Thanks,
Chris

I think I figured it out. I had an incorrect backing on either the tensioner or idler pulley and the A/C belt was rubbing.
