Do the serviceable front driveshafts only have 2 grease points? Thats all I could find while under there. I also found the at one point in this discos life some one installed a pull/push style lever for the center diff lock that sits along the frame on the passenger side. They also installed a white light under the rear bumper shining straight down wired in with the rear fogs. Odd.

The last one is not accessible with the driveshaft in the truck, you need to remove the shaft to grease it. Good idea to do it at each oil change. Requires a grease injection style needle to lubricate.

It was a pretty common failure for folks to keep driving them after the u-joints were worn to the point the driveshaft flys off going down the road, it almost always destroys the transmission and sometimes the transfer case when that happens. The driveshaft will start chirping at low speed when it is about to go, serviceable shafts are not very expensive, you should probably put it on your to do list.
