    I replaced the right front wheel hub assembly last weekend. Now, whenever I get over 60 MPH the ABS (!) light comes on. It will turn off again after I come to a stop, then good until 60+ MPH. I'm guessing I got the sensor hole in the dust cap misaligned slightly. Can I get a confirmation before disassembling the whole danged thing again? What is the proper alignment? Centered?

    I have the EXACT same problem down to the RH side. I was extremely careful to align the oval hole in the dust cap with the sensor, but whoever had the wheel hub off before did not install a dust cap. Near as I can tell there is no dust cap on the LH side, either, so that may be part of the problem if the new dust cap on the right side affected the voltage sensed by the speed sensor.

    I saw a recommendation here to "Recalibrate the ABS, look for post #15. I might try too get my barely bootable XP up and running and have a go at finding whether there is such a thing on Gen2's.

    Attached is a technical manual that may help us troubleshoot the speed sensor.

    HV Battery down to one bar, fan on. Disconnect battery and fan off, 4 bars and dash lights. Huh?
