"Sealed for life", as it relates to drivetrain components, is self- fulfilling, Haha. NEVER, EVER trust that.
Lubricants are broken down over time by much more than simple contaminants. Shear forces are primary, as are heat and moisture.
Add to this; every single time that I have changed fluid in an otherwise "sealed for Life" component, I have discovered that the fill level is significantly lower than the factory recommendation. This must be due to fluid going somewhere. Regardless of the absence of visible leaks, weeps, or seeps.
Seriously: never trust old lubricant. Never, ever.
