Thanks for the advice...yeah the symptom of the brake
and ABS light being lit up in dash and it not
registering speeds before 30 mph was fixed last time
with the rear wheel speed sensor. This time the ABS
and Brake light come on, but not ALL the Time!
Usually after a bump. My speedo now, registers low
speeds but at freeway speeds it jumps up and down
about +/- 10 mphs of what I could possibly be going.
So I'll throw a rear speed sensor at it since THATS
cheap.
Those front ABS Sensors sound crazy!!
