Is the IMS bearing issue a real problem?

— Although the IMS bearing issue is a real problem, could much of what we read about on the Internet be more “hype” and uninformed panic than real statistical metrics?

What’s the failure rate of single row IMS?

According to information published about the Eisen IMS Class Action Lawsuit, the single row IMS bearing used in 2000 through 2005 model years is reported to have an 8% failure rate, versus less than 1% with the dual row IMS bearing.

What happens if your IMS fails at low mileage?

Are there any IMS bearing that are not serviceable?

Some late model year 2005 engines were also fitted with a larger bearing that is not serviceable without a complete teardown of the engine. It is impossible to verify what bearing is needed by VIN or engine number. Visual inspection is the only reliable method to determine which type of bearing is needed in these engines.

When did the IMS bearings come out on the 997?

Figure 1. Inner workings of a 997 engine and IMS bearings. According to research and multiple surveys, the results of which were published on Rennlist.com, the IMS bearing issue could be narrowed down to 997 models that were produced in late 2005 and early 2006.

How many cars are affected by IMS failure?

Even out of that short time frame, less than 1% of vehicles were affected by IMS bearing failure. So, it’s possible that most of the talk and panic found across the Internet may have been blown relatively out of proportion.
