I have a '93 Audi where the A/C compressor pulley bearing recently started to make a grinding noise. I realized it was the bearing and opted for replacing it, since I've done some pulley bearings on my newer Toyota.
I got the bearing out (not easily) and it's the original Japanese NSK bearing and I've had a hard time finding the right bearing to replace it. The bearing part number ends in DU which I've read means that bearing is Dry, Unlubricated. I have found a replacement bearing that is not DU. It has lubrication in it.
Do you think there will be any issues with using a standard, lubricated bearing? The original DU was probably used for a reason. Maybe due to heat?
