Pothole, Your 97 probably has a double row bearing.... I don't have a ceramic number for that one.. yet. When I pull the one out of my 98 I will find one. For you to use the single row you will need to use Wayne's kit or build one of your own. The ceramic bearing has a 16,000 rpm limit, where as steel only has a 11,000 rpm limit, so realistly ceramic should last over twice as long as you don't rev over 8k. Just repack the bearing with quality grease, I perfer to leave the seals on when installed.
The double row in my 98 will be replaced with a single row, as the double rows are not as strong as the single row, because they can't load the bearing with enough balls....
