At almost 150K, my starter was making a grinding noise so I bought a remanufactured one and installed it. Though not as bad as the old starter, the new starter was also making a grinding noise. Feeling disappointed I searched online and found this thread. I followed the instruction, took the starter apart, cleaned and applied new grease, put it back together and reinstalled and the grind is all gone. Success!! Thank you! I returned the old starter and saved myself a hundred bucks.
