On my 1998 galaxy with 170,000 miles, my originals lasted 124,000 mles. yes I have had the car since new and do all my own servicing. I replaced them with ford originals at 124K which were different to the original ones on the car and replaced the osf one againat 150,000 miles. Not happy with the new Ford tem lasting only 26K, I bought a cheap one from e.bay and so problems as yet. regards
