3ch or 4ch ABS?

[dougcw]

I have a 2002 WS6 without TCS. Do I have 3ch or 4ch ABS? I guess my real question is which pair of Moser Axles do I get? I bent the hub on my driver's rear axle and want to replace both of them with Moser rather than GM. Help please.

You have 3 channel. To make sure, you should only have a speed sensor in the differential.

4 channel abs is for traction control cars, they have a sensor at each wheel in stead of just one in the center.
