Has anyone personally changed the rear diff fluid on their RHO?

I was looking under the truck & there appears to be only 1 fluid access plug, located near the middle of the diff cover.

This leads me to conclude there are only two ways to drain the diff…crack open the cover…or, use a suction pump thru the fill hole.

Or, do I have the wrong diff? I recall watching a tech change the fluid on his TRX on YouTube. The TRX definitely had a drain plug near the bottom of the “pumpkin” and a fill plug at the top, behind some bracing. I thought RHO used the same diff as TRX?

I don't have a picture, but the drain is on the front of the diff, driver side. It is a 1/4" drive plug

even though it's a trx forum, this was helpful:

Differential and Transfer Case Fluid Change- My Observations

Here's what I learned after changing the front and rear differential fluid and the transfer case fluid today. Total cost was about $200. Half of that is the t-case fluid, which is Mopar proprietary. I generally followed this video, which is excellent: Always pull the fill plug first before...

Found it! Lighting in my garage cast a dark shadow, so didn’t see it last night.

Thanks Gram10!
