Case 70xt Final Drive

I recently purchased a 2003 70xt. She runs good for almost 5k hours. Changing fluids. I don't ask unless I can't seem to search out the answer. I'll call the dealer also.

What are the opinions on final drive fluid? Does it just use the system fluid unlike the older gear motor machines? Is there service I should worry about?

Seems like a weak point on these machines and no one is talking about. The manual only touches on the topic.
