Don't remember seeing this discussed explicitly...
Is it reasonable to assume that the 2 types are designed for the same life expectancy, and that when one fails the other is likely to be on its way out too? Of course, there are many parameters in play, but I'm wondering if seeing the knuckle seals in worn condition would likely imply the axle seal is on its way out too... Or is the outside one just more exposed to the elements and therefore generally failing earlier?
I'm thinking about this in terms of trouble indicators and advance notice.
(and yes, if it's opened up it's probably a good idea to do both anyways...)
thanks
