Hello I am new to he club and particularly interested in this thread. I have a 2019 Cherokee Limited with the Active Drive 1 and the rear diff is leaking around the pump motor, (just replaced by a dealer). Long story short I don't trust the dealer to touch my vehicle again, ( I won't go into the details), and I want to remove the pump motor and check the O-rings that are supposed to be installed, I have the O-rings on order, and am trying to figure out how to add fluid back in as I am sure it will run out when I remove the motor. Again this is an Active Drive 1 and there is no reservoir on the top of the rear diff. Any advice

Thanks for the reply! I suspect the O-ring may be damaged/missing. The motor does seem to be seated correctly, ( no gaps ), but fluid is coming from that area. I did use an inspection mirror and saw the plug you are talking about, near the vent but on the opposite side of the case seam. I will have to get back under there to get some picks, but it's leaking bad enough that the bottom of the differential case is wet and also some on the exhaust. And an oil spot on the driveway...

Power train warranty is 5yr/60k (I think), and I have over 60k on the vehicle. I do have an extended warranty on the vehicle, with a 200$ deductible. My plan is to fix the leak myself if it will be a relatively easy fix, but I'm not sure that is the case. Attached a couple pics, this is after cleaning the differential off good and pulling the vehicle out of the garage onto the driveway.

Gary, that is what I suspect. I have the O-rings ordered. Sounds like I will have to do the bleed procedure as well?

I assume this will run the motor/pump to purge the air out without setting off the service 4wd fault?
