ABS hubs on a non ABS XJ?

ok so i was wondering. my jeep is not eqqupped with ABS. but i wanted to put ABS hubs on my jeep b/c i can re pack them through the ABS sensor hole on the hubs(or so i ve herd). i just need an idea on how to plug up the hole for water and stuff after i grease them. i was thinking a zirk (??grease fitting, grease nipple??) fitting tapped into the ABS sensor hole would work great b.c itd be easy to grease and would keep water and debris out. what do you all think????? ive got a friend with good hubs off an explorer with the ABS fitting that are in good condition with fresh grease thatd hed let go for like $20 (for the pair) im thinkin about getting them but dont know how to plug up the ABS hole. BTW the hubs are the same bolt patteren and spline count. it had a D35 front axle (IFS)

The ABS sensor does not attach to the hub on an XJ.

ok. does anybody make hubs with a grease fitting?

good quality ones last 50-100k without a grease fitting .. so why worry about it?

I have 93 hubs on an 89 (I also changed the rotor).
They were from an XJ with ABS.
