Has anyone changed the PTU and RDU fluid in their Cherokee yet?

Can't find much of anything online other than general confusion. Was planning on doing it come spring.

According to the service information, there isn't a drain plug on either the PTU or the RDM. Looks like you'll have to siphon.

The PTU takes 75w90 and the RDM takes AAM 70w80, if it helps.
