Strange Rear ABS Incident

[Cmcm3]

Hi all,
I've got a 2003 running pretty much stock except for Bilsteins and aftermarket performance brakes. The truck has 230k astonishingly uneventful miles on it. I have literally never experienced a single glitch. Scheduled maintainance and obsessive fluid changes are my approach. The other day I'm on a long left sweeping on ramp at about 50 mph when my right rear (outside) wheel goes into massive ABS vibration lockdown for about 3 seconds. I know it sounds short but it felt like forever. It was nerve racking when I thought of how it might have gone for me in the wet. Anyone experience this or know what's up here? Bad sensor? Satan possessing my baby?
Thanks in advance.

Someone else had a similar thing happen. Wheel speed sensor was the culprit I think.

Hey so something very strange happened to me yesterday while driving home from skiing that fits into this thread nicely.

Here is the scenario... While driving.... on the right side of the truck there was compact snow and ice. On the left there was more slushy snow on top of ice.... I was going about 20 mph because that was what traffic was traveling at. There was maybe 40 ft behind me and about 40 ft infront to the next car.

The road was straight with a gradual decline (this is a highway so nothing crazy)...

All of the sudden I heard crazy beeping (assuming atrac timing out). And my whole car viscously veered to the right which I had to massively steer to the left to correct. Luckily I could save it before I hit someone or drove into the snowbank. All is fine except for my confidence... And the rediculous glares from the cars that passed me after this episode...

After this occurred I locked my center diff. (Mainly to turn off atrac...) because I think that it might have actually cause this problem.

Some background info, I've skied at least once a week since I could drive, so snow driving is not foreign to me. I've never experience anything remotely close to this. I know that my tires are getting close to being replaced but I have driven up skiing with my subaru with near bald tires and never had a problem.

Can anyone explain WTF happened! As this really shook my confidence in my rig!!!

Thank you

Don't Know if it was similar... however just like you it scared the s***... err piss out of me; hasn't happened since. Still haven't changed wheel speed sensor
