I heard that both ptu and rdu are undefiled at factory? Is that true?

It was a typo - "underfilled".
A typo makes some folks lol here as they cannot figure out the correct word.

Gotcha. There are a small number of folks reporting slightly undefiled (sorry, I had to....) Power Transfer Units, and/or Rear Differential Units, but it's not wide spread, or extreme. I still think it's a sound practice to replace those fluids every 20-30K, it's easy, and only takes a half quart each. My $.02. (you can search this topic for more detailed discussions)
