Do they have grease nipples? Haha sorry i couldnt help but laugh at that. I think mine are out of grease due to an unfortunate noise the aircon makes when its turned on an off? sorry to ask alot just so novice at this stuff.

They are a sealed unit as far as I know, my girlfriends TL starting making a grinding noise that was found to be the aircon pully, the pully can be taken off, but the bearings can' be re-newed, hers was replaced with a new compressor under warranty so didn't really worry to find out about replacing bearings and what not.
