problem mostly is caused by the speed sensor but not the RABS system itself.
RABS valve?

What year is your truck? I know the 87 to 96 or so RABS was a complete joke of a system that doesn't work very well. The RABS valve is expensive here, never mind where you are. I would just bypass it with a section of steel brake line and pull the ABS fuse.

For a 2001 Ford, I would try a junk yard with a roll over, not one hit in the front end, or try buying one from a dealer. I guess the real question is why do you think it is the RABS unit causing problems, besides an obvious leak?

They almost never fail, but they still suck. 
If your speedo is working, it's most likely either the computer or the valve.
I still say bypass it and be done with it. It's a lot cheaper.

My truck is 4WD Off Road and unfortunatelly a Rock hit it right over the Nitrogen acumulator and was broken.
ABS brake sistem was designed to provide a better breaking control to driver, specially in a emergency breaking like higways or wet floor. By passing it will disable this system leading in a less protection in case of emergency.
ABS system really Help a lot...
For the 2001 truck, there is a lot of RABS valves at www.pamsauto.com

I hear they do fail, and suck after mine went out on my 91 explorer.
Got a new one from napa for $170, heres what shows up for you on napa online. Oh yeah at auto part stores it's called a Modulator Valve, instead of rabs valve. http://www.napaonline.com/masterpages/NOLMaster.aspx?PageId=470&LineCode=UP&PartNumber=5 70029&Description=Anti-Lock+Brake+System+(ABS)+Modulator+Valve+-+Remfd

Thanks Fmodster, that looks very similar and the price is better than OEM and yes, the proper name is modular valve.
At least there is an alternative.
