I do not have any advice (yet) but I have a question. How do you know that is your problem? Just currious.

I need to replace mine. I know I have a broken wire in mine, I can twist the conductor counter clockwise near the top tywrap, and the ABS will work for a few days. I read that a forum member had peeled the insulation and spliced his broken wire and covered with heat shrink... for me... not that lucky yet.

If your model is like mine, u will have to remove the axle all the way out so the sensor ring can be removed. Good time to coat the axle with silver anti seize. Good time to clean your brake pistons with spray brake cleaner since they are off the rotors. Also a good time to replace front pads if they are worn. If your bike is up in the mileage, may be a great opportunity to install some new wheel bearings.

Loosen the axle nut while the bikes weight is on the front tire. Then jack up the front to where the front tire is just before clearing the floor. This takes the bikes weight off the axle. The axle should slide right out. If it does not, try a few rubber hammer blows from the right side. Rem to loosen the right side axle holder acorn nuts.

Make sure that when u install the abs sensor ring, it's on the left side and it is properly rotated and nested against the ledge on the left lower leg. All this is in the service manual.

Torque axle nut to no more than 65 ft lbs.

front wheel ABS sensor on.... 2008... any advice?

old thread but working on a 2008 Ultra w ABS. Pulled front wheel for tire replacement and the sensor is cracked at the wheel. Going to replace but question is - does this simply plug in under the fairing? (working thru manual as I type)

I ran the wire and saw it goes up to under the fairing somewhere but havent pulled the fairing yet (in middle of tire replacement so that is first priority)

I ask as if it runs allll the way back to the ABS unit that would require pulling the tank etc, tons of unnecessary work (to me)

Also, do the front and rear need to be replaced in pairs? rear looks fine but worth asking as the bike is apart.

Thanks to anyone (not just the OP)

Follow the wire. I had to replace mine a month or two ago. On my Street Glide the wire went up the forks and plugged in right under the fairing. Was very easy to replace and I only replace the front. It was around $90 at my local dealer.

Dunno. Its not like a seat or other used item that is easy to take on/off and has no effect on how the bike runs.
