Got up under the JK this weekend and noticed there are no grease fittings on the tie-rod ends, ball joints, etc. It did not even appear there was a place to put a fitting on these. Are these items sealed now not requiring periodic lubrication (grease). I have not checked the drive shafts yet.

 

They are sealed units now, and "supposedly" need no lubrication...

The best suggestion I have heard yet is to get a needle tip for your grease gun, and use it to squirt some grease in there. That is what I am planning to do once I get 20K miles or so...
