Im new to with forum, but it looks like there is alot of knowledge here. My issue is a noise in my rear end it just kind of developed driving along a normal trail, no harsh conditions, its kind of like a chunk sounding noise but it still acts and drives the same at first I thought it was a u joint snapping but upon further inspection I think its my pinion gear in the rear diff, anybody have this issue? Thanks for the help

Pinion gear was common issue in the 11/13 models . And if that’s the case it will get worse really quick. The new replacement is upgraded from the factory with helical gears instead of straight cut.

To upgrade to the new style you would also have to upgrade the ring gear right? The helical pinion and straight cut ring gear wouldnt mesh would they?

Cheaper to buy new diff than to repair the old one . You can get a new diff from dealer for less than 700$. If your dealer likes you. A rebuild on yours will be over 400$

I do all my own work, ill probably just split my diff and replace anything that needs replaced if its only the pinion I should be in for a little over 200

If it needs a pinion you will need a ring as well. Or you are just wasting money . It will fail again .

The ring has wear whether it had damage or not . You start mix matching parts and it will accelerate the wear of the ring and the new pinion . Plain and simple the 11/13 diff was junk from the factory . If you would have went in and set it up the day it was new it would have made it a lot longer . Lots of threads on the forum of then hand grenading with out warning . Most were extremely noisy from the factory . It was just a turd and they finally got around to fixing it in the new models .

Or you can bullet proof it with a Maverik diff . Which is what most do. But it’s not cheap . It’s around 1500$ for the kit.
