So I just finished installing my PR44 this weekend and noticed there was no drain hole in the diff cover:thinking:. I guess you have to pull the cover to change the fluids now? Wondering how those with Dynatrac axles do it.:beer:
We do it the way it was always done - pull the cover, clean, re-install cover and fill. Truthfully, it's the better way to go as it'll give you a chance to inspect your gears and do a more thorough cleaning. Here's a write-up that'll help you out:

Loosen the bolts and splash.
Clean everything and re-silicone the cover for install.
