Error 55 abs light on legacy

My Legacy has its abs light on and error 55 on dash, I have looked it up a bit and seems to be a speed sensor, Where are they located?? Is it more than likely a replacment part job or restting the system?? Which is more than likely main Dealer I suppose

theres a sensor on each wheel mate!!!!

I replaced all my wheel speedindicators, nly a little sensor with wires comin out, connects into the cv joint, and reads the abs ring, i got mine second hand, a stone got caught inbetween the sensor and abs ring, and scratched the sensor, all it takes is a small scratch to disablethem sensors,
best of luck with it, but its nothin major
Oh you wont have abs as long as sensor aint workin
