When my A/C compressor is online, it whines. The noise wasn't there when I picked the truck up at 28,000 miles, so it's degradation of a bearing or something somewhere. (No, it's not the cam chain tensioner...I've already been through that fiasco
Pretty sure it's not the pulley since that's always spinning. And I just had plenty of A/C work done a few months ago; the compressor passed plenty of performance tests while still making the noise.
I'm thinking it's a bearing in the magnetic clutch or another component. Has anyone fixed this? How hard is it to replace or repair the cluch? Do I have to remove the compressor from the A/C lines to do it, or can it be done in place?
Since a new clutch is $140 my first step will not be replacing it as an experiment...
