Hi I have a 2004 Dodge Ram 1500 SLT 4x4. I have 4 wheel disc brakes. Just bought if 2 months ago and am working on things. My front Left hub bearing is going out so plan to change, I looked under and there is an ABS wire going to it, but on the right front there is no ABS wire. Could some one in the past changed the hub with a non ABS one? My ABS dash light turns on with the key and goes off when starts. The code on the Option Report. Shows (BRRS--4 Wheel Disc Rr Anti-Lock Brakes).. Which I think says Rear anti lock only. are there plug-ins for ABS on all wheels if I change out the right front hub also. I'm a little confused and any direction here would help. Bill

 

Yeah, that's rear wheel only abs. Is there a wire for the connector from the hub on that side to plug in to?? It's possible that someone had a bearing go bad, and the only thing the parts store had on the shelf was the 4WAL unit....... only difference in them is the sensor.

 

The front is for the cruise control.
