Rear speed (ABS) sensor on 2004 4WD Expy?

[bertro]

Hi.

So it looks like my rear speed sensor might be dead. The ABS kicks in when not necessary and the 4x4 Hi light flashes when I put it in 4WD.

Does anyone know what part I need to buy and where does it go? I've read conflicting reports: some forums say there's only one speed sensor and it's on top of the transfer case. The Ford parts website sells rear left and right speed sensors that are supposedly installed on the wheels.

which is it? can anyone confirm?

thanks!

For 04 4x4.. the speed senor attaches to the wheel hub...

thanks! so that means there are two in the back, right. gotta figure out which one died.
Are they a pain to replace?

Piece of cake.. IF you can remove the rotor
