I need some help with my rear diff. Was doing some routine maintenance before a 1400 mile trip this Friday. Found this in the rear diff when I drained the oil. 2016 Sport. 3.73 gears. 31k miles. No noise when driving. Am I good to go for the trip? I suspect the dealer wont be able to fix this tomorrow.

There are chunks from the top and a chunk from the bottom.

The only time your spider gears turn on pavement is going around corners, and they don't turn much. Highway I wouldn't worry too much so long as all the chunks are out and the ring and pinion look good. Just don't do any one wheel peels on soft terrain.

At 31k, they shouldn't be chipping like that. Spin the carrier around to make sure that the large crosspin is securely in place. Just strange at that low of mileage that it would be like that. If it were my Jeep, I'd drive it on the trip.

Should be covered under warranty.

Dealer squeezed me in to help me out. Took it apart, and they dont have the spider gears to put it back together. They are on a back order. No loaner cars available. Trip cancelled.

Sorry to hear on the trip cancellation..

Did they give a reason on why this happened? Is it just the spider gears or pinion's as well?

That sucks. Too bad they couldn't just get a loaded carrier somewhere.

Any kind of warranty work they're gonna take the cheapest way out and probably stick him on the bottom below the paying customers.
