No matter how good the parts are, there will be wear and shavings. One might think they should be flushed out? What if the vehicle is submersed in water?
Don't get me wrong, I agree with you. I hate these "sealed for life" units. Who's life??

We never had any Cherokees come into shop today. I took a look at mine in my garage at home and could not see any drain plug. Hopefully we will have come in tomorrow.

On my last vehicle (Explorer/Mountaineer at ~130k miles) the front diff had no drain plug so I got to pump it out, which wasn't any fun. In fact it was a PITA. The gear oil is so thick it isn't very easy to pump and the tube kept flying off from the pressure. You use a hand pump and fish the tube in from the fill hole...

Good luck!

I have done that in the past on people's vehicles. But it is not the preferred method. If that is the only choice we have on the Cherokee, then that is what I will do. I just want another opinion before proceeding.

I really hope they were smart enough to have a decent way to drain everything...be pretty silly to not be able to (easily) drain the fluids on a technically off-road capable vehicle

I am going to drive up on ramps this weekend if I get time and see if I can spot the PTU fill plug.

You cannot see the PTU fill plug unless you remove the Heat Shield. There is no drain.

Really? I thought I saw one. In the next two weeks I will be getting into it, I have not had time yet. The oil change is cake, it is the rear diff and PTU I am holding out for, hoping to do it all at one time.

I haven't forgotten about you mudman1. We just haven't had any Cherokees come in for service.
