ABS, Trac off, low tire pressure lights

[raceman02]

I changed my LF wheelbearing on my 97 Grand Prix GT about a month ago. As soon as I changed it, the ABS, TRAC off and low tire pressure lights all came at the same time. I didn't think nothing of this b/c I pluged the wire from the new bearing back in. After about a week of everyday driving, the lights went off. But recently, all three of the lights decided to come back on as I'm driving down the road. When these lights come on, it seems like the steering tightens up. Would anyone know whats going on? Do I need to reset something? I checked tire pressures and they are fine...

It could be the other hub's wheel speed sensor malfunctioning, a bad wiring harness to the hub, or even a bad new hub.

Not trying to hijack this post, but I have been searching for an answer for this exact same problem. It was intermittent at first then it became constant. One other question I have is how big of a job is it to replace the front hubs.

BNaylor,

Thanks for the great guide to replace the wheel hub assy. I think that I can manage the removal and reinstall, I already have the torque wrench from Sears. I also have the 36mm and 35mm socket for the 1/2 wrench.
