Good to know, and glad you caught it.

Did you check the VIN range that was published? Was it in the range?

Single row- 8-10% failure rate. Double row- Less than 1%

If I had a single row bearing car, I would give serious consideration to a clutch IMS bearing replacement. I have a double row bearing car and I'm going to wait till I need a new clutch before I worry about the IMSB. At a 1% failure rate, I'm not overly concerned (hopefully the stats are correct).
