2 things going on, first is that there is a cork "O-ring" under that screw on cap which keeps the inner and outer shafts centered and aligned, and also keeps the grease in. No one had ever greased mine either, and it did exactly like yours. The Spicer kit took care of mine just fine.
The second thing that may or may not be an issue (hence the driveshaft shop comments) is with a 4" lift, the shaft may be spending too much time extended too far, and the splines are shot.
I'd say if you just want it "not broken", get the cork and grease it up, and see what it feels like. Grease everything else too, if they didn't do that one, they probably didn't do the others either, and 1989 grease is a couple days past it's 'Sell By' date. If it's still floppy and worn feeling, get a shop to rework it for the right spline engagement, and probably use it as a chance to get all the U joints and Cardans etc updated as needed too.
