Default having problems on check, abs and brake lights on

hello i just wanted someone to help me on this. I checked out autozone to check what code was coming out, so they checked it out and came out to be P0715 Input Speed Sensor Error, P0720 Ouput Speed Sensor Error. so got them parts and changed out both of them. after 100mile drove, and still the same lights came on. now every thing is working now but the lights are all on. some one help me on what to do now? OH I ALSO HAVE A 99 DURANGO 5.2

Sounds like a speed sensor that is located on the top of the rear axle.

Yup!

Reset the PCM. Could also be the ABS module going out. Heard rebuilt ones on ebay for about $60.

Reset instructions.
Engine Code Index (Check Engine Light?)

Default check engine light,abs,brakes

I had the same problem a couple of years ago on my '98 Durango. Changed out the sensor on the diff. and it fixed the problem. Just recently, my check eng. light came on and Autozone checked it. It said "Failed output shaft speed sensor" or "Electrical problem". Everything else seems to be working OK. When the sensor failed the first time my speedometer would quit working below 15mph. This time the speedo is working OK?? Any help would be appreciated.
