I don't have either, I have a 1500. I'll go take a look in the AM. I've never seen any sensors coming off the rear end. Only brake lines.

 

Rear Wheel ABS don't have a ABS sensor. They are controlled by the portioning valve and the ABS module. HOWEVER, If you have rear DISK brakes, well then THAT, my friend is a different story. I'll tell you, I'm willing to put my pink slip on it, all rams with drums ATLEAST have RWAL also know as Rear Wheel ABS.

 

Huh. Interesting. I know for sure I have 2 Wheel ABS, must be rear then. My mistake.

 

Yeah, that's what we've been trying to explain to you. We ALL know for sure we have RWAL (or "2 Wheel ABS"). But that's why this forum is here, to learn stuff we didn't know.

 

Ok I did a search and found this thread. I have a 94 1500 with only rear wheal anti-lock brakes and my ABS light is on. If there is no sensor, what is causing the light to come on?

 

It's not that there is no sensor, it's that it is not the same design as the front wheel ABS uses.

 

I lost it. Did a quick reply but gone. Okay I find this thread interesting, but a little confusing. so let my add some more confusion. My truck a 1999 2500 4x4 V10 Club 8800GVW. An early model with drum brakes in the rear. Okay 2 or 4 wheel ABS. The rears are controlled by one sensor located on the meatball (rear Diff). Look on top and you will see a sensor wire. The system monitors ring gear speed and when sensing a quick reduction it controls the hyd pressure to the rears keeping them from locking up. My fronts have ABS sensors on each wheel. So is this a 2, or maybe a three wheel system since the rears are controlled as one, or a 4 wheel system. Simple as far as Rams go, it is a 4 wheel system, even though the rears are treat as one unit. I think folks get confused when they don't see sensor wires coming off each rear wheel. If your new to Rams get use to it-the confusion-that's what makes them so interesting, and one hell of a truck.

 

Five year old thread?

 

I have 4wd or 4x4 not sure correct way to explain . but i know autozone asked me which i have. 4 or 2. Im so confused now.

 

Do you have wires going to your front wheels? If yes it's 4 wheel if not it's 2 wheel. Also man this is a 5 year old thread.
