After I had these bearings installed I started getting a loud noise after 8k miles. I then looked at the box the bearings came in and it said made in China. The noise kept getting worse and finally couldn't stand it anymore. I replaced them at 10k miles with Timken bearings and no more noise. I have put 20k on the Timken bearings and they sound the same as they day I installed them. (QUIET) Never cut corners on bearings is the motto of this review.
