I'm replacing my rear wheel bearings and noticed after taking them off that there is no grease on the spindle. There isn't supposed to be any? Also what is the point of the hole at the bottom of the knuckle/bearing bracket? I'd assume there is supposed to be grease in the knuckle and the hole would have a plug in it. Thanks!

OK, first off I've not noticed a hole in the "bottom" of my rear knuckles. If there is, if I was to guess I'd say to eliminate condensation or someone drilled a hole for who-knows whatever reason. If it's in the side it's likely to fit the abs sensor or screw it down. Maybe post a picture to insure we're talking the same spot in the knuckle.
Whether you use anti-seize (which I do) or use grease on the spindle shaft, I don't know it makes a whole lot of difference. Know that though the FSM torque specs on the spindle nut is something like 170 foot pounds, AFAIK it was revised to about 200 foot pounds for all C4's some time in the past. Best double check for yours to confirm those numbers.

Does that answer your questions?
That answers my questions! Where would I be without you guys??!!
I'll be in the garage shortly and take a picture of the hole. It's not the ABS sensor hole.
Thanks. I looked in my FSM and it doesn't mention grease either. I was just surprised not to find grease in there so I figured I'd ask. I'm also wondering why the hole is in the bottom of the bracket.
Now that's interesting, I've not seen a hole like that before. I'm not going to swear to it, but when I had mine apart, I don't remember seeing a similar hole in mine. I suppose it might make a difference, mine has drum e-brakes on it.

What would be the point of the hole? My thinking is that water and debris can get in the hole, which wouldn't be a good thing.

Anyone else come across this?
If you want pure guesses: weep hole in case you drive through a stream and get water in the hub. Grease drain in case you blow a hub seal while driving 150 MPH+, Curiosity item so someone will ask why.
I honestly haven't a clue on why those holes would be there.
