    I ran a search, couldn't find anything. The bearing in the A/C clutch assembly is making a racket. Being the fact that the whole clutch assembly is $110 and a bearing is $10, I decided on the latter.

    Anyone swapped this bearing? Any help would be appreciated, regarding the clutch removal and bearing replacement. Thanks!

    Need to go down to auto parts store and buy a AC clutch puller/installer. Back out nut on the compressor shaft.Thread on the puller pull clutch/pully assembly and remove pully/clutch assembly. Take out the snap rings that hold the bearing in. Gently tap out the bearing. Reinstall. Dont tighten up the compressor shaft nut too much or the clutch faces will rub. There are measurements for the air gap between them. But i usually just get the faces close enough togeather so the clutch faces dont rub. Also allow a little extra gap for heat expantion.
