Hi all. I have a sable 2000 3.0L OHV 130K miles with the dreaded chirping noise coming from the rear of the engine. I read a lot about replacing this part without using the special tool. I plan on marking the orientation of the sycnro to the engine and the sensor orientation to the sycnro prior to pulling the old unit. That should put everything back in the same orientation. The question I have is that good enough or do I need to time it somehow to the crank or cam like old distributors need? I didn't see anything much in the Chilton or Haynes books on the removal other than using a special tool. Any Ideas? Does computer compensate after the unit is put in the same orientation relatively as the old unit?
