I have a 2000 Ram 2500 4x4 V10 sport quad. Speedo doesnt work till 25mph, rear brakes touchy upto that speed. Im gueesing the sensor on rear is bad? any pics on how to replace it? is it hard to do? Iits a plow truck so alot of surface rust on that rear end so I'm hoping its not going to be a headache getting it out.

 

They are generally fairly easy to swap out, and I wouldn't be surprised if that sensor was indeed the issue. If the PCM isn't getting reasonable speed readings, it will confuse the ABS as well..... thus, turning on the lite..... I am surprised you aren't getting a CEL as well.

 

Mine was easy 2 bolts and a screw driver to wiggle n wedge it out of the diff. I took the spare tire out for more room ..
