My Chiltons and Alldata books have no procedures or graphics of the clutch and pulley build up.
I must replace the pulley bearing due to much noise while a/c is idle and engine is running
My local pro tool sales man will supply the correct puller in the a.m.
I am requesting a scanned image of the clutch/pulley assy, and re&re write up be emailed to: nozel99.at.hotmail.com (you know what to change for it to go through...grins)
Thanks in advance Rolf Zell

Rolf,
If it was the bearings, the noise would increase and decrease with engine RPM's. Have you had a good look at the tensioner yet? A worn tensioner will rattle/bang with A/C on at idle, but will clear right up as soon as RPM's increase.
Doc
With engine warm and in drive and stopped for light a/c off: howls. With engine warmand in drive and stopped for light a/c on Howl gone! And howl gone in all conditions above idle. Compressor pulley bearinfg has now been replaced with some improvement (howl is less noticeable).
To note: belt idler pulley bearing checked, not cause, ditto for tensioner pulley bearing Rolf
