I think you got it reversed? Does Jerry work on them for a living or is he (obviously) a forum wizard who hears the 'hearsay'? And your awful new here to already be in the posse Lol.
Not sure how to say it any more simple than I know of them going bad, first hand including my current ride.
Keep on swinging between his legs is all I can say. Simply put, CHECK YOUR TIMING CHAIN IF iT RATTLES. Despite Jerry the jeep fairy saying its going to last for x amount the truth is they've went out as early as to be covered under warranty and lasted as long as 3 and 400k mile engines. It's MECHANICAL and therefore VARIABLE.
If someone makes you feel better by having half a million posts and saying your jeep is good to go, by all means, sleep good to tonight.
^^Nice.. Please do us a favor and troll somewhere else..
Look man, we aren't a bunch of ass holes. Now, are there some on this site, sure, but not all of us are.
All we want is acceptable answers to questions people ask.
Sure, timing chains break. Sure, they stretch. Happens to every vehicle. Obviously, if your timing chain is making noises, or perhaps banging on the timing case cover, you should go and get it checked. But for the most part the timing chains on the 4.0 last as long as the engine.

Precisely because I am a newbie to Jeep ownership, I value the learned knowledge of others who are willing to share their experiences and opinions with folks like me. I always assume, when entering a new arena (like owning a Jeep for the very first time) that there are people out there who know more than I do...and I'm not in the least intimidated by that. Nor do I need to aspire to know it all. If my timing chain begins to rattle, I'll get it checked out and be grateful for whoever brought that to my attention. And I will also be grateful to those who remind me that generally it isn't something to lose sleep over because timing chains appear to be historically a strong point of TJ's. The whole idea is to enjoy the ride isn't it? Maybe timing chains prefer low humidity over high humidity, maybe they fare better in some states and not in others. The point is to share information and apply that, when necessary, to one's given Jeep and situation. So thanks for the heads up on the timing chain watch. But I don't think it qualifies for the apocalypse. Finally, I've never met Jerry B, but if I ever did it is my opinion that I actually would like him even as he may run Jeep circles around me. If that qualifies me, in your opinion, for discipleship then so be it!
Didn't mean to upset your Internet life guys. Sheesh.
No, just don't need know it all assholes who works on planes so he knows everything about jeeps.
Never had a timing chain go on any of my I6 engines... My buddy has 360k on his. Again, from hearing from many others on the forum and the trails, Timing chains don't seem to be the issue with these engines.
Yes, they could go but that isn't the norm....that simple.
