ABS/brake light

The ABS and brake light are on constantly in my 2000 F-150 2wd 5 speed manual with 155K. This happened 3 years ago and the brake guy just put in some switch, I think it was on top or the differential. Is this likely to be the problem again? Is the the switch cheap and easy to replace?

The switch for the differential is about $ 20.00 at the Ford dealership. It may be your problem , but NOT always.

Go get the codes read, then it will lead you to what you need to fix/replace.

Yes, do what Bobby said. If they did replace something on your diff. its your speed sensor. You have a 3 channel abs system

Problem

It is most likely the rear speed sensor, which is located on top of the rear differential. This part usually costs about 30.00 and is the most common problem. As long as it is the yellow ABS light, and not the red brake light, this is most likely going to be the problem.
