abs light and trac off

[92BonnevilleSE]

When I turn the car "on" but not start it, I hear the noise as if the abs kicks on. And once I begin driving, my low trac light will come on a few times and then the trac off will turn on. This even happens when car is still in park.. I have replaced both front hubs a few months back and the rear ones were replaced last October.. and once, while pulling into my driveway, the abs kicked in when I applied the brakes.. where should I start?

With a scan from a scantool that can read ABS codes (Tech2 or higher end scanner). Otherwise, you are just throwing parts at it.

I agree. While one of the wheel speed sensors is the most likely culprit, there are other causes. Also, recent replacement of the hubs does not rule one of them out, either. There have been more than a few where the WSS have gone out within a few months of replacement.

I agree with all of the above. Get it scanned. That way you know what you should be looking at and for.

Well i jacked the car up last night and checked yhe tire for play, the front passenger shook a bit and I just replaced the inner tie rods so I'm guessing the hub is bad again =( at least its still under warranty!
