Hello,
Today i had a problem with my '91 K100 driveshaft, the grooves in the driveshaft worn out and I couldn't ride it any more. Out of the blue the rear wheel stopped turning when i wanted to drive off a red light. It showed no sign of dulling prior to this.. The bright side was that i had a refurbished driveshaft from the last time this happend (about 10 years ago) and I managed to get that and changed it on the side of the road.
The thing is that i read in some topics on the forum that it should be lubricated? I am just wondering what exactly should be lubed?
I mean should i lubricate the driveshaft grooves where the teeth of the differential hub enters in it?
Like inside here? Where i painted red? (this is not mine, i just found the photo on google to show you)

Is there a special lube or can i use just grease?
For the moment i did not use anything, because i did not have any grease (and also i didn't know if i should use any).
However, in the "housing" of the teeth of the differential hub i did found some old kind of paste (maybe old greese), i couldn't tell. Should i remove it and clean it and add some new also in the housing, or just where the teeth enters those grooves in the driveshaft (like in the picture above), or where exactly?
I didn't think to take a picture of it to show you the condition of it, but i will do that if i have to add grease since i will remove it again... I will also try to take a picture of the teeth of the hub.
This is what i mean by the "housing" of the teeth of the differential hub (green marking): (again, not mine)
