I actually updated our IMS page again to include a more sure-fire way of identifying which IMS your engine has. I've had so many discrepancies in what an engine had versus what I thought it should have had, I can't guess which ones are single row bearing IMSs, hence the need to visually identify each one.
I also took some video of the failing IMS bearing as well as some photos of another dual row that was just sent in with 70,000 mi that completely came apart in the engine. It's posted on Youtube:

As you'll see in the video, it's physically possible to check for how much play there is in the bearing and gauge it's condition. |
Charles: Thanks for taking the time to give me a detailed answer. It is much appreciated.
The video is worth a million words, especially because it is so well done that it takes a lot of the mystery out of this particular weak point in the M96 engines. It is an excellent supplement to the article on your website.
Keep up the good work!
Regards, Maurice.
