My driver's side ABS sensor is bad and I'm going to replace it next week but, I seem to remember Michael saying you need to replace both front sensors at the same time or the ECM won't recognize it. Replace just the broken one or both?...they're $50 a piece. 

I lied, abs/brake light is back on and off again

I just replaced the rear diff. sensor hoping it will clear my problem...the abs/brake light comes and goes and sometimes when I touch my brakes the ABS goes off and my rear wheels lock up. Would replacing the front 2 sensors and leaving the stock rear one cause this? They're all new now and I haven't taken for a test drive yet...hopefully the old gal will make the 4 hour trek to Indianapolis tomorrow.

Us old guys don't care for abs. Especially in washboard. Sometimes you just gotta have full brakes and skid. Remember pumping brakes to avoid skidding in slippery conditions? I was driving my wife's 06 and going downhill on washboard. Hit the brakes and they gave me nothing. Almost went off the road on a corner. Weird feeling. Hit the brakes and they don't respond even with heavy pedal. My friend removes the abs fuse when offroad.

ABS brakes are not designed to stop you quicker on any type of slippery surface. ABS systems are designed to allow you to be hard on hte brakes and allow you to steer around what ever is in your way. Is that the best way? Not in my book. I prefer to have some stopping power. My truck has RWAL and when it kicks in the stopping distance gets a lot longer. It is along the lines of having your car apply brakes without any input from the driver because they aren't paying attention (like the commercial about a woman backing out of a driveway with her two kids in the back seat and she almost backs out in front of a school bus. The reality of it is PAY ATTENTION!! not have your car participate in the dumbing down of society.

I replaced my rear diff. sensor with a BWD part from O'Reilly's...it was faulty from the getgo, lost my speedo and brake lights came back intermittently. Ordered an SKF brand from Rock Auto, supposedly it's an exact OE part...got my speedo back and no brake light! But, I'm still fighting ABS going off from time to time and my rear brakes locking up, it's scary. Any suggestions? Bad control module?

Could someone look on their truck and see where this ground is tied in to? It was tucked under something and disconnected when I found it, then I grounded it on my fender and I think it was getting noise and making my ABS go hay wire.

I would say its suppose to be grounded. I would redo the that back to a clean body ground.

If that one is the one I am thinking then it is attatched to the bed on the right side just behind the cab close to the bed hold down bolt in that location.

Picture?

All it did was get a screw to the bed mount (or in that vicinity). Nothing spectacular, just a screw.

No kidding!

Seen those  new car commercials  lately??    the ones  that  show    'smart'   decisions  made  by  collision  detectors?    I especially  like the one  where  the  guy  is  cruising  down a  road,       he comes  up behind a  slower vehicle  (while he was  looking  elsewhere)  and   the car  goes   'beep',  and  stops  for him.    This whole time  the driver  looked  at the  dash board  (which was  lit up like a Christmas tree)    BEFORE  he  looked   ahead!!!       

People are going to get  really too   reliant/lazy/comfortable/false  sense of  security   with  these things..

I've only heard  that  we need to replace  the  fronts  as  pairs,   not so much  with the  front AND rears..

I  thought if  your speedo  was working properly,  the  rear sensor  was  good.

Would a bad front wheel bearing make the ABS/Brake Light come and go intermittently? I just used a pry bar under both front wheels and looks like a bad lower ball joint on the passenger side and a good "thud" on the driver's side with no ball joint movement. I would assume wheel bearing, and that was the side that popped up on the snap-on scan tool as a bad sensor.

you said  your  rear brakes  'locked'  when you just  'touched' the  pedal??       I'm leaning  towards  something other than sensor!

ABS going off randomly! Driving down the road and I touch my brakes and the ABS goes off and then I have to stand on my brakes before going through a stop sign! I assume it's from my driver's side wheel bearing going bad.

Picture please?! Where does the ABS module ground to? I replaced all the sensors, one front wheel bearing and my light is still on.

Sensors... If its front sensor you must replace both as a matched set. Rear sensor the speedometer will act weird or not work at all.

Thanks, all the sensors have been replaced with oem sensors. I think I need to head down to the dealership and get a fancy OBDII reading.
