Over-active ABS?

I just changed out a wheel bearing yesterday, long story short, now my ABS seems to go off on the slightest touch. Sometimes I'm fine, but sometimes I try and brake in a parking spot for example and without any tire slippage (dry pavement, less than 2mph) the ABS start hummin' away. Hell I almost hit a guy in front of my cuz the truck just wouldn't stop moving forward. I hate ABS anyways, I'm thinking of just pulling the fuse and being done with it then popping out the iodiot light in the dash. Is there a way to adjust the sensitivity? There's no way in hell I'm pulling that wheel bearing\hub assembly again (4wd) just to exchange it for ANOTHER wheel bearing. I still need to do the other side, and there's no way I'm doing 3 wheel bearings in 1.5 days, especially since I broke my finger yesterday doing this one.

Reading your other post on it you may have changed the wrong side.
Are you using good oem type wheel bearings or the el cheap o ones?
If ABS light is on you need to get it on a ABS brake scanner and check for ABS codes to find the problem.
Post back any codes you may get.
I would not pop the dash light bulb.
Tampering with a saftey device can get a person in a world of hurt.

Fuse pulled.
I changed both wheel bearings, one of them was a cheaper bearing (only 250$ gee cheap eh? lol) and had a sensor that did not have a 90deg angle to it but in fact came straight up and out of the hub, I had to zip tie it to the knuckle just so it wouldn't rub on my disc. Make note of this, anyone buying a bearing make sure you get one where the wire comes out of the sensor block 90degs to it, not straight up.
At any rate it's not rubbing on anything but I have a feeling it's a junky sensor, the ABS pretty much goes off anytime I hit the brakes under 2mph (stop signs, parking, etc). I yanked the fuse because:
1)I truely don't want to change ANOTHER bearing, they won't "return" this one, they will only exchange it for another junk bearing.
2)I hate ABS anyways, it's gotten me into more close calls than non-abs any day of the week. ABS only, and I quote, "allows you to steer while in a skid". I've been driving for decades without much issue and have NEVER been into a skid related accident where ABS could have helped, this is my first vehicle with ABS, and I haven't enjoyed abs since I bought it, especially with all the ice around here. More often than not the ABS just continues my slide 2x father than it would have if the tires would have just locked and dragged to a stop.
3)I have a sinking feeling this bearing will die in the next year or so anyways and I'll replace it with a better one and re-place the fuse, or maybe keep the fuse out, truely the only reason I would ever put the fuse back in would be to a)sell the truck or b)make that damned idiot light go away.

I had an almost identical problem with my '98 blazer. It had nothing to do with the wheel hub though. Mine started doing the same thing (abs going off when trying to park, pulling into the driveway) for no reason. I hit a tree in my yard because it wouldn't stop, so I feel your pain.
Anyway, I took the brakes off, had the rotors turned, bled the lines, replaced the pads (all things that sorta needed done anyway), blew on everything, sprayed some windex on it (OK, I made that up) and put it all back together. Hasn't happened again in two weeks.
I have no idea what was wrong. . .nothing was obvious. . .but it seems to be fixed. I've heard theories from people who don't know anything really, and they have told me that maybe there was some sort of lubricant or film on the rotors causing them to slip. I don't care what it was, it's fixed now.

Thanks for the reply. I'm coming up on a front brake change anyways, maybe after I throw new pads on and change the rotors I'll clean it all up, check the wires again, and throw the fuse back in to see what happens.
