I went in to my 23,250 mile 1998 Box and as the pictures show the dual row bearing was on its way. I pulled the seal on the bearing and found the bearing cage was broken but still in place and the balls just starting to go but races looked good.......there was surprisingly very little metal. When I pulled the bearing there was some in the tube but again very little, used paper towels on a set of magic fingers first with diesel fuel on the towel, I have a borescope and there is now nothing in the tube. I pulled the filter and it was spotless, dropped the oil and pan also spotless. The oil and filter had 500 miles. bought the car with 9100 miles in 2017. the oils been changed 4 times since I've had it with one being at the PDI. every filter has been cut and inspected with each. Did a 5000 mile cross country trip last July and changed the oil before I left and when I got home and inspected that filter as well, all have been spotless.
I know I'll be flamed, but I think I'm going to put it back together. I ordered a LN spin on filter and mag drain plug. I have a filter cutter so I'll change the oil at 50 miles first and inspect the filter, then 500 and then 1000mi. Your thoughts........

Very interesting. Seems to be the perfect example of IMSB failure in a car that has not been driven enough. I inspected the IMSB on a 2000 Boxster with 115,000 miles on it, I pulled the outer seal and verified the bearing, it was fine. I put a new o-ring on the flange and put it back on, it has been running ever since without problems.
Was there any grease left in the bearing... or oil?
I find your course of action reasonable. With the bearing seals in place it seems to me that very little metal would be circulating.

Are you saying you found the cage like this after removing the seal? Looks like a perfect cut.
