possibly moisture in the ABS Module? I have never encountered that problem before....

I agree about the serviceability of these hubs. Ihad a 95 Riviera that had over 200,000 miles on it with the original front hubs!!!!

How did you determine it to be the front hub? Yeah I went to work today, and no issues, and I even drove through puddles. This is really getting me tweaked....I so miss not having to mess, my last car had no ABS or Traction control, unless you count the computer behind the wheel, and it did just fine.

Hey, I am having a similar problem right now. But mine is not speed dependent, but more just whenever it feels like it.

With my car, I can drive it fine most of the time. But if I try to take off hard, sometimes the ABS light will come on. Not sure if it is worth it yet to replace the entire hub (new only a year or so ago) just so the ABS light doesn't come on every now and then? I probably will.

As for figuring out which one is bad, I was able to borrow a Snap On scanner and retrieved C1225 code from it. I made a post about my issues here. Other than with a scanner, I don't know of any other way to figure out which hub is bad for sure.

Not sure what that means. But with that note, I would double check all the wiring. I would make sure the connections are clean and good. Maybe clean them with electrical cleaner or something. Also, something else I did was check the resistance of each sensor and wires. All were about the same ~1050 ohms. But check yours and see if you get similar readings. Most of the time, from what I know, replacing the entire hub will take care of the problem.
