I can't believe it! You wouldn't believe a Timken product would spoil so quickly, but it did. So I have doubts about the product and I think it is not a genuine Timken part. I've bought Timken before and they've lasted a long time. Those four months are just ridiculous and it doesn't feel like you're an inferior and terrible substitute. So I had to replace a part and this time I know this is a genuine and reliable product from the company that stands behind their product. Wish it was the same with this one. Too bad
