Had my shop do the LN bearing today. The old bearing (single-row, car is an '01) looked to be in great shape, well-oiled, solid, etc. I guess I was hoping the old one would be about to fall apart, but good news and now feel good that that particular risk has been addressed. They're not all about to grenade I guess.

most replacements will be of "good" bearings....trouble is you dont know when its will go bad - if ever I suppose....

send me your bearing and I will photo it under the microscope for you...that's the real tell tale of wear

BTW WTG - another IMS thread and a happy one - I guess

Where did you have it done? I'm thinking of having 3Zero3 Motorsports do mine.

Unless you have an IMS Guardian and it does what it's supposed to do, right?

That's the problem I have with this swap -- Porsche engineered the thing to last for the life of the car. Okay, some are clearly flawed but they tested the things to last. LNE provides a replacement part...one that's engineered to last 50K miles. In 40K miles, that's a bearing that's expected to show wear at that stage while the Porsche version shouldn't...it's all a bit scary if you dwell on it too much.

We'll just have to wait until the early adopters start experiencing failures to know how long the upgrade lasts. That will be my canary in the mineshaft to prompt an IMS Guardian install.

Wait, you're going to wait for an upgraded IMS bearing failure before you buy a monitoring system from the same collaboration?

DreamCarrera

No surprise here...

Good luck with the upgrade, I hope it performs as well as the original has for you.

I had Dart do the work, they've done quite a few, and very reasonably too.

Thanks DreamCarrera, me too!

I have a 1999 tip with 138,000 miles on it. Car has been perfect and I've had to do nothing other than routine maintenance. My mechanic is trying to sell me on the LN Engineering retrofit arguing that because the bearing will wear like other parts-- and given the mileage on the car-- I should get it done. I am conflicted like many others. Paying $2k now sounds a lot better than $18k later. I am having a hard time pulling the trigger...any advice?

I have 20k miles and had bought an extended warranty under which my RMS was fixed. I have a year left on that, and am looking into an extended powertrain only warranty. I'm planning to compare the price of that extension with a preventive IMS retrofit.

That bearing wasn't engineered to last. Maybe they THOUGHT it was, but it obviously wasn't. If it had been, they wouldn't have redesigned the bearing and flange multiple times over the years. I had mine replaced at around 110K miles and even though mine was in good shape, I'm glad it was replaced.
