Why has there not been any right ups on this EPS Bearing? I would think that someone out there other than someone from EPS has used this "permanent fix".
Anyone??

I'm beginning to understand why Jake Raby gets testy at times.
The IMS bearing design possibilities were studied at length by Jake and Charles Navarro, who even hired a bearing engineer to participate in the process. Bearing size, shape, material of construction, cage design and materials, and even the races were studied and possible configurations were tested, often to destruction. No design or idea was discarded until it was thoroughly evaluated. The result was the ceramic hybrid single and dual row ball bearing retrofits everyone knows. And with more than 18,000 installations running around, none of which use any type of oil squirting system on them, the validity of their development speaks for itself.
As for adding an oil squirter to any type of ball or roller bearing, there are drawbacks. Believe it or not, you can actually get too much oil into the IMS, which causes a new set of problems. And where the oil comes from is critical; the design used on the LN IMS Solution draws oil directly from the filter, where it is both clean and not robbing oil flow from other moving parts. Other systems pull oil from an area that already has oiling issues, plus is both the hottest and usually dirtiest part of the oil system, and then sprays it directly on the bearing.
LN has proven that the right ball bearing works well with just splash lubrication, without introducing other potential problems. For years, many owner's of 2006 and later cars that carry the oversized non serviceable IMS bearing have had good success with just removing the rear seal on the OEM bearing so it can be splash lubricated. Some Porsche dealerships even do this when other maintenance work uncovers the rear of the engine and the IMS flange. So you have to ask yourself, if all these cars are doing just fine with ceramic hybrids, or even OEM bearings with the rear seal removed, exactly what benefit is going to be gained by adding a squirter to the system?
