FWIW the LN Single Row Pro installed in my 2003 S at 42,000 miles failed at 77,500 miles. If there are any debris particles in your oil and they happen to get splash lubricated into the IMSB, the harder ceramic ball bearings will use them to grind up the relatively softer steel bearing cage and races. Who knows if the original IMSB that I had replaced would have lasted?
