This 2014 Jeep Grand Cherokee V6 runs very nicely at 202k miles…
But it has a concerning LOUD CLUNK/SNAP/POP noise coming from below when doing a hard acceleration from a stop. What’s the PROBLEM??
The drive CHAIN inside the one-speed AWD Transfer Case has STRETCHED enough to start JUMPING teeth on the gears!!
Turns out replacing this chain is a fairly straight-forward repair that can be accomplished without removing the transfer case from the vehicle…

Those things don't hold very much oil, less than 2 pints if I remember right. What looks like a small seepage of fluid can be deadly.
With that fliud in the transmission looking that bad I would have taken off the cooler line and ran all the fliud out.
Thanks Ivan!
They call it lifetime fluid in many of them. But that isn't something I'd recommend. Although it is a good idea to use the exact fluid Chrysler/Jeep recommends.
The best part of Ivan's repairs is, that it's just like us working on our own vehicles. No fancy lifts, and doesn't have $100,000 in over priced tools. You gotta love it.
carlyle makes a set of very short hex and torx sockets, i use them for jeep cherokee oil filter adapter gaskets
Have you tried left hand drill bits to remove bolts/studs? They're a nice product.
There's probably a local concrete plant that can deliver you an 8'x8'x8" concrete slab. You could have a little site prepped for it and they'll set it in place. Then you could have a portable mid-rise lift to put on it. Better than what you have to do now.
Ivan, spoil yourself with a cheap 4 post lift. Game changer.
You are too intelligent to be doing oil changes.
I'll have to remember this one. Nice job my friend.
WOW! 200K on maybe the first full ATF change! I would be interested to see if the new fluid cleans out too much of the old stuff too fast that is sealing the rubber seal lips in the pistons. I hope the new fluid renews the rubber faster than the goo sealing them cleans out. Many Trans have gone south after a wee ell meaning ATF change at high mileage. I would recommend changing it in stages with a few thousand miles between so the sealing goo doesn’t clean out too fast. Start with 10% of the volume changed then do 25%, Then 50% then 75% then full change. Do each at oil change intervals. I’ve had good luck with this method. Please keep us updated. In about 6 months.
Im only 58 but i dont lay under a vehicles anymore. Lol
Ivan STOP, you doing that hurts MY WALLET!! Ouch that is not good!!
You Ned a bigger garage so you can put a lift in, you're getting to be quite the mechanic.
Wow. Sloppy chain! Nice fix on that. I woah GM did that easy job lol. Now i. Jealous lol. Nice repair ivan!! Ughhh i hate plastic pans!!
Superwork on the chain/transfer case. – Solved the problem…! Kudos
I've seen this happen with a lot of Cadilac XT5's. But usually by the time the owner wants to get it fixed, it's way too late.
That looks like the ZF transmission in my BMW.
Had same symptom with old AWD Exploder (BW4410 w/ viscous coupling) few months back (+300kmi). Sounded like a jackhammer accelerating from a stop. Difference in chain length near immensurable but driving perfect with the new one.
As for what caused the stretch, front prop shaft had been binding. Replaced just the rearward joint only for the forward U-joint yolk to sheer a week later. And that took out the trans pan, damaging the valve body and took out a chunk of the bellhousing.
Not my first rodeo into the T-case, the VC had been replaced ~5 years prior. Already dealt with the crossmember's corroded bolts back then. Even better the chain is no longer mfg. Out of stock all over and no aftermarket either. But ebay to the rescue, managed to score the very last one.
I watched one and a half minutes and suspected the transfer case as well. I've done two of these Lets see if we're right.
