Re: Front ABS Sensor - why so expensive?
Sure it is replaceable!
The first thing I did was take it out to inspect it for metal shavings & cable damage - it took me 10 minutes to get it off.
Motorcraft sell the sensor as the BRAB 115 - without the hub.
I can get an aftermarket hub with a sensor and I can get aftermarket sensors ( for $15) - but only the similar looking rear sensor.
