I have only done the rear sensors, start by removing the four bolts holding the backplate. you can now see the two bolts holding the sensor bracket to the axle casing (this bracket is usually cracked and needs replacing) i find that removing the two bolts by unscrewing untill they touch the disc then cut off the heads with a hacksaw and remove the last piece with pointed mole grips is the easiest way, use slightly shorter bolts to replace. you can now see the exciter ring for cleaning or what ever. to replace the ring it is a full hub strip down. hope this helps
