That guy needs to get his facts straight. He starts by talking about LN Engineering, and the points to what is obviously not an LN installation but one of the DOF systems pushed by other vendors telling you (correctly to some degree) what is wrong with it. The he “exposes” some sort of “hidden” LN recommendation about removing the rear seal on the OEM bearing. LN has been a proponent of removing the rear seals on OEM IMS bearings, particularly the non serviceable versions that cannot easily be retrofitted, for years. And while he acts like it is some sort of secret, it is readily available on the LN website, and has been for years. And the LN hybrid bearing balls are not coated with “a ceramic sealant”, the entire ball is made from a ceramic material that is much stronger than the steel balls used in the OEM bearing.

He has a problem with machining a small openings in the bell housing flange for an oil line, as would be done with the IMS Solution; NEWS FLASH: There are literally hundreds if not thousands of cars running around with the Solution with a notch machined into that flange, some with more than 100K miles since it was done, without any problems associated with that notch. And they DO NOT LEAK OIL, regardless of what the speaker says, and they do not flood the IMS Solution with high pressure oil. The DOF may suffer that problem, along with all its other shortcomings, but the LN IMS Solution does not.
