Checked my XR this morning. The rumors are true. The front Rubi diff no longer has a drain plug. I wonder if this is a parts-related change, or a design-related change. In any event, I don’t like it.
Ha try that on a Ford 9" style diff .I see no reason for a drain plug on a diff. In fact the Jeep's are the only vehicles I have ever seen with a drain plug. I find it odd and concerning that it would put someone out to do something as simple as removing a diff cover to drain fluid.
I change mine annually given I wheel quite a bit. I'd argue if you do, and enter water -- you should change more frequently. At the same time, potting the sensors as preventive is a common thing owners should consider doing early on. In my case, my lockers were already starting to have issues engaging after 3k miles. Mine will get potted after break in at first oil change which I'll be doing at 3k.I will double check, but I think it was missing from my Rubicon as well. V6 eTorque delivered in early September.
OK - can of worms here, quick glance at the maintenance plan it says to change front and rear axle fluid at 40,000 miles if using your vehicle for police, taxi, fleet off-road or frequent trailer towing.
it doesn't seem to list any light duty (my words) interval for changing.
So is 40K a reasonable mileage to change front and rear diff fluids?
