Years ago I got in new brembo rotors and put New 'made in Mexico' SKF bearings and races into them using valvoline Synpower grease which is a high moly grease. Recently i have been hearing a bearing type of noise, audible mostly at slower speeds, and convinced myself it was from driver's side front wheel bearings. I replaced the drivers side today. After cleaning the old ones with a toothbrush and gasoline, I can see absolutely nothing wrong with the rollers. no visible flatspots from moly sliding, cant feel any roughness when spinning them in the races. The races have some lines in them that cannot be felt. I installed the new SKF bearings( made in China) despite the old ones looking to be in very good conditions, and the noise appears to be 60% less, but this is also what I wanted to hear, so i am not saying for sure that the noise is mitigated 60% with just the drivers side bearings replaced, My ears are a bit stuffed from surfing today. I am doubtful the noise I was hearing could be from these nearly pristine looking rollers. So say there has been some sliding/ flat spotting of the rollers going on, one would expect any moly induced sliding flat spotting of the rollers to be visible to the a pair of 2x reading glasses, no? While i still have some Synpower grease left over, I used red masterpro high temp wheel bearing grease from Oreilleys on the new bearings Not sure if it has moly or not, but I assume no as it is clearish red, not chalky red like redline CV-2 and valvoline synpower is nearly black. Thoughts?
