Front wheel bearing replaced - now ABS light is on

Okay, I did some searches but couldn't find anything really conclusive. Had a whining front wheel bearing. Bought a replacement, just telling the parts guy what car I had (wasn't asked with or without ABS). Had a shop press it in. At first, the ABS sensor wouldn't go in as the snap ring opening wasn't positioned correctly. I fixed that, got it all in, ABS light is on.

I'm trying to get answers on two things:
1. Are there ABS and non-ABS bearings?
2. Does it really matter which way the bearing is pressed in?

I went back to the parts place, they said the same bearing is spec'd out for with & without. I looked at the bearing before it went in and can't recall seeing any difference in how it went in.

If none of the above matters, anything else it could be that went wrong during the R&R? I did check the connection, looks okay.

Thanks,
BB

When I replaced my rear wheel spindle and hubs my ABS light came on. It took 3 days for the computer to "relearn" the signal aparently. After 3 days the ABS light went out and has been ok for 9 months now. This happened even though I was using the same ABS sensors. Aparently being disconnected can affect their relationship with the computer. Wait a few days of normal driving and see if it goes out.

Thanks, but this has been on for 3 months. Car's so old and has so many other problems it's hard to know where to start but I sure would like my ABS again!

Yes same wheel bearing for ABS non ABS but one side of the bearing is black I believe and that side must be pressed in facing the sensor. So the bearing is more than likely pressed in backwards.

Okay, I guess the next one I'll buy will make sure it's spec'd for ABS. I am assuming that you can't pull out the existing bearing (if it's an ABS type) and just reverse it (i.e. it would destroy the bearing)?

I'm pretty sure there's only one bearing, just ABS. It wouldn't be cost effective to make two types of them. The bearing was put in backwards. This actually happened to me too, only they completely broke the bearing putting it in, and I gave them the knuckle assembly directly instead of having my car serviced.

Removing the bearing will destroy it, they can't be reused.

An ABS wheel bearing has a different colors at each end. Black at one end, red on the other. One would think that the manufacture would color the sensor end in red. But the correct answer is the black side goes toward the sensor. If you ever screw one of these up, as I have done, you'll never forget the bearing location. Hope this helps.

The best way to know for sure is get a paperclip or like metal object. The Tone Ring is really just a magnet built into the bearing. Place the paperclip on each face of the bearing. The paperclip will stick to one side and not the other. The magnet side goes toward the ABS Sensor.
