ABS issues on 2003 Oldsmobile Alero

[James]

Over the last 8 months, the car has read a code of “Short or open circuit Right Front Wheel Speed Sensor”(something like that). We replaced the RF wheel bearing hub assembly. It worked perfectly for about 3 weeks and then the same issue came up(pretty well the same). This time, instead of them being on as soon as you turn the car on. They come on when the car hits a bump, or sometimes even after 20 feet of driving.

Is this another faulty Wheel Speed Sensor, or should the wiring harness be replaced? (Note: The bearing itself is perfectly fine.)

The wiring near the control arm seems to be fine, and not pinched, or broken.

The repair might be costly, but what will it cost to replace the vehicle with something reliable?

99 percent of the time with gm cars the problem is in the harness . I don’t care what any one says I splice and solder wheel speed wires all the time and never have a problem . just carefully open the harness and give a light tug on each wire . usually the bad one will break very easily .
