if the splined shaft is too worn (0,2mm max play is the spec., at least for 1600/1750 it is, can't see why the 2000 would be any different) there is not much you can do, but buy a new rear prop section for 250 bucks.
the knurled nut just needs hand tight, but I do a tiny bit more with vise grips as you can't really get a good grip with your hands all covered in grease!
In fact its worth undoing it when greasing to make sure the grease is going in properly and is not all dried grease.
That sliding joint requires greasing every 4k
