hi ,
i have a mk3 mondeo which has just had a new crankshaft sensor, on the mondeo when fitting your suppose to leave a one mil gap so has not to hit the flywheel inside the belhouse, maybe this could be the problem , not 100% sure but would check it out all the same, good luck.

the fact its wearing out suggests it rubbing against something on some cars as said a spacer is fitted so it doesnt touch the flywheel taking a look at the sensor you should be able to see if its been worn by metal to metal contact or not
