How hard to replace front wheel (ABS) sensors?

[Guest Kitskaboodle]

Mine have badly frayed cables. <img src="http://forums.aaca.org/images/graemlins/frown.gif" alt="" />

I can see where they enter in through the wheelwell to the strut tower and then to a connector housing.

How hard is it to feed in and hook up new sensors? (in the front)

Any special things I should know?

Sometimes they can be pretty difficult to replace. Not in the areas you are referring to but in trying to get the sensor out of the knuckle. They are made to slip into a hole in the knuckle and then held in place with one Torx bolt. The bolt comes out easy but the sensor sometimes is very tight in the hole. In order to not damage them I have had to take the bearing assembly out of the knuckle. I then put about a 1/2 inch socket on my 1/2 inch drive breaker bar and then positioning the socket on the inner end of the sensor and hit the bar just outside of the knuckle and this pushes the sensor out of the hole. Sometimes they are so tight I still damage the sensor end to the point where they are no good. I pick a socket that is just slightly smaller than the diameter of the sensor.

The easy part is disconnecting the connector under the hood and pulling it back through the hole in the sheet metal.

If the sensor is working I would recommend simply repairing the frayed area with some tape or some sort of protecti
