You can grease the thrust bearing, but use grease.
Any grease. Axle grease, black grease, Ron Paris grease (my favorite on thrust bearings, had a little tub for years) but use grease.
The thrust bearing on the slipper turns so little you can almost get away leaving it dry, but a little lube won't hurt it either. This is as opposed to the thrust bearing in a ball diff where you need to pack that sucker full. The reason for the difference is the thrust bearing at the ball diff will trap the grease in the outdrive, the grease on the slipper thrust bearing will sling itself all over the inside of the gear cover.
