*Model year 2000 and 2001 engines came from the factory with either a dual row or a single row bearing IMS. 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.
**Engine must be disassembled to remove the original bearing. Installation of IMS Retrofit™ MY06-08 makes the bearing serviceable without engine disassembly in the future.

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. It is worth noting that failure rates are considered to be significantly higher out of warranty and in the years since this data was made public.
The 8% failure rate cited by the settlement documents is not far off of the calculated L10 life we have been using for the last 8 years!
With half the load capacity, it is clear to see that the reduced load capacity of the single row IMS bearing is a significant contributing factor to the increased number of failures and that oiling alone is not the cause or solution to IMS issues…MORE
Oiling is just one part of the problem. The solution is simple. Eliminating the grease seal opens up the bearing to the oil located in the “integrated dry sump,” aka wet sump where all the oil is housed…MORE
As you would imagine, the IMS Retrofit kit went through many iterations during development, including forced oiling of the ball bearing prior toselecting a ceramic ball for its performance…MORE
