My ABS light is on and my local mechanic said its the rear sensor. How do I locate it and replace it? Any particular place I should buy the replacement?

 

Having a year and model would help immensely.

 

it is on the top of the rearend with a wire coming out of it.

 

Sorry.... It is a 1999 Ford Explorer Sport

 

GOOGLE IT. BUT it could be fouled from brake dust. Specially if you have semi- metallic pads. Also make sure your fluid is full. Bang on reservoir with butt of your hand. If the float gets too low snd stuck there it will make stuff light up. Also before you go spending money on parts. Find a big parking lot or back street with no traffic. And do a few quick stops like a person just pulled out in front of you. Dont stand on it but stop fast with a purpose. Sometimes that jars the pads a system enough that it will right itself. Specially if you know you havent had to stop quick in a long while. Good luck PEACE and safe traveling.
