I’ve had my IMS replaced this year. You won’t appear in the LN IMS database and they won’t honor the warranty unless you mail in your old bearing.
The current LN warranty is 6 years or 750000 miles for the current generation IMS pro bearings. The IMS solution is still a lifetime warranty.
Do the current generation pro bearings need to be replaced every 6 years or 75000 miles? I don’t know. I think the real answer is change your oil and drive your car regularly. If you are going to do a new clutch every 50-75k miles, it’s a modest increase to service the bearing.
