I know this is an old post and there is other info around here on the drive shaft zerk fittings, greasing them, etc...but, I could not find details on my particular question/issue. So here goes...
I went to try and grease the zerks on the drive shaft, etc with grease gun in hand..blah blah blah...but, I looked closely at all the zerks (3) and did not even see a tiny hole or opening of any kind at the tip of the zerk fittings. In fact, it looks like it is solid metal and what should be a zerk is just a zerk looking metal plug like insert. I even wiped them down thinking maybe dirt, etc was blocking my view. Unless I'm loosing my eye sight or going stupid, was there perhaps a change that Isuzu made to later model VX's that converted the zerks into just zerk-like metal plugs where you can't (or shouldn't need to) grease them??
For those who have greased the drive shaft zerks, have you been successful at putting the grease gun tip onto the zerk? Does it even latch on or stay in place enough for you to grease them? Do you see a tiny hole at the zerk tips?
I thought maybe I'm going crazy but my grease gun tip doesn't easily sit on the zerk and well there seems to be no hole or entry point for the grease to go into the zerk! Ummm....hmmm...what?
