bad bearing
found a bad bearing when i did my rotors last weekend. must be a material defect of some sort, all 4 were changed 30,000 miles ago and this one is the only bad one. hard to see but has pitted rollers. race didnt look damged at all. had no noise or vibration, i was pretty shocked to have found it. the weird thing of it is that back 4 years ago when i put new bearings in was because of a bad bearing in the same position, drivers side inner. that time it was the race that looked bad, almost like it had sat with water in it, you could see where each roller was in the race. i still have that race but the picture i have for it doesnt show up very well, this one aint great either but at least its somewhat veiwable.

yes they are "china" bearings, but arent timkins also made in china anymore? you cant seem to get anything that hasnt been outsoursed to that country. "they" say there is much to worry about with the middle east, i say china is what really should be worried about. but thats another topic altogether. if its a material defect, you would think that all 4 would have done the same thing. the other 3 bearings were fine.

Some companies have better quality control than other companies.
It's been my experience that if the part was made in China, the QC is likely lacking....
Do you still have the sales receipt?
If so, I'd be taking them back to where you bought them......even if you don't have the receipt, I'd still try to take them back.... maybe the next batch of bearings will be good??
