My 99 SE 3.4 V6 has a problem with the front brakes. It was scanned 3 times and it was the RF wheell bearing (bad sensor) I thought this was odd to have 3 defect (Precision Brand) wheel hubs but then at a local Tuffy Center they replaced it with a Timken bearing and I still have the same results. The guy then tells me that its possible that when I drive the voltage in the the ECBM is dropping from 14.3 to about 2 volts and thats why the ABS light keeps coming on. Also when it starts from a cold start I back out.I keep getting the LOW TRACTION light then the right side makes a scraping noise then the TRAC OFF and ABS lights appear for th rest of my trip. HELP!

Look at the wiring harness going to sensor very carefully for damage, is where I would go with this one. They can be sneaky like that.

What codes are listed in the computer, I am assuming it is the one for that wheel.
