Wheel pulsing means that your brake rotors are warped. Warped brake rotors will trip the following sensors......

Service Stability System
Trac
ABS
Brake

Most of the time, i would get all of these lights at once. Had bearings and tie-rod end replaced, still got these lights. So, i had all 4 rotors turned and BINGO, no more lights. Bad wheel bearings will also cause these exact sensors and lights to be tripped, but since you had the wheel bearings replaced, i would try having all 4 rotors turned. Pep Boys was the cheapest at $140 and takes about 30 min (MIdas wanted $320 just to turn 4 rotors). Unless you take all 4 rotors off yourself, then you're looking at $32.

$847 to replace the wheel bearings? My gods you got ripped. Wheel bearings are $150/side and cost about 30 minutes labor time. So, $330-$350 at the most is what you should've payed for that. And a 2001 SSEi is in no way anywhere near being a POS. I've put over $2000 out of my own pocket into mine so far since i've had it about 8 months, but that'* because the previous owners didn't take care of the car.

Thanks, Matt. Don't think rotors are warped - no pulsing when I brake; pulsing comes from stability system responding to some false signal. Thinks it'* controlling a skid, and modulates the left front wheel. Pontiac dealer wouldn't use aftermarket parts - GM gets $350 EACH for those damn things.

I also get a general retard when driving along at a constant speed. No lights with that. Any other ideas?
