I undertook the job of replacing the front wheel bearing on my wife's
2000 Elantra. I have use of a press. I have the spindle assembly(hub
with rotor attached) off the car now, but I'm not sure of a few things.
1. How to remove the snap ring that retains the bearing. I tried
freeing it up with a chisel and trying needle nose, but it seems pretty
stuck. I also have a mid-sized pair of snap ring pliers, but they
won't expand that far.
2. How do I separate the rotor from the hub. I first thought that the
two holes on the face were for threading bolts in to separate the two.
Then I read that some hyundai's have two screws that hold the rotor to
the hub. I didn't look closely inside these holes, but maybe there is
a hex head screw inside. I also read something about using a slide
hammer. Anyway, I'm stuck here too.
3. What keeps the hub retained in the bearing. It seems like the
transaxle would hold it to itself, but I was thinking that the
transaxle isn't held in that strongly and that maybe the hub locks to
the bearing somehow(other than the press fit).
Any help anyone can give me with these questions, would be greatly
appreciated.
