Hub work
I know there is a o ring on the hub and i think there is one on the locking hub but i have manually locking hubs and have a stick shift for 4WD so im not sure if the locking hub has on or not. and if the locking hub do have on should i replace the hub and locking hub o rings or just reuse the old ones. Another question has anybody ever changed the needle bearing in the hub, i read the grizzle web page of how to grease them but i cant find some about changing them? Also i have read about people greasing the hub thru the ABS sensor hole, does that help the hub last longer or is there no reason to do it, if it does help how do you do it, i figured i might as well grease everything while im at it.

As for greasing the main hub, that's the theory, to help them last longer. Here's a couple links on that. Good luck.
