Exactly how many timing chains have worn to the point of needing replacement that you personally know of?

The only person who used the word "forever" is you. Don't put words in peoples mouths they never said or exaggerate what was said. The most anyone estimated here was 250k miles with one more individual mentioning over 300k miles of use on his... so no one is claiming anywhere near "forever" on steel timing chains.
And your stated qualifications
of "Keeping in contact with Jeep dealers and working on Jeeps" are no different than half the people on the various forums... which makes you no expert.

Lol life of the engine, forever. Sorry, seemed like an appropriate word to use.
And the fact that I know of more than I can count, one being my own, qualifies me to not jump on the because I heard so bandwagon.
I'm sorry it upsets you to be told that these chains are very capable of wearing out well before the engine internals.
On with the swingin' folks. 4.0 chains do not wear out. Questioning this is stupid. End thread.

In all the years I've owned internal combustion engine vehicles I've been more concerned about oil consumption, valve jobs, carburation, overheating, and electrical issues and the like, way more than timing belts/chains. The only exceptions were my kids Honda cars that, at the time needed replacing (along with the water pumps for convenience) every 60,000 miles.
That someone with Jerry's track record and experience with Jeeps suggests that the timing chain in my TJ is going to probably last longer than I may drive my TJ is not only comforting to me but reassuring. I respect that opinion over wannabe "experts" who obviously have yet to walk a mile in B
Jerry's shoes or ridden a mile in his Jeep. There's always people who try to trump experience and knowledge with opinion and hearsay. IMHO.

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.

We all know timing chains can go at any time, its a mechanical piece that can fail. All anyone one was saying that generally the timing chain will last the life of the motor. Dont come in here with 16 posts and trying to start flexin yer pretty muscles acting like yer king shit to jeep mechanics. These are all posts from guys stating their experiences. DONT BE A DICK

Look I don't smoke every bowl Jerry packs, but I'm not about smoke a 2 day old newb's bowl with some 'jeep dealership contact' over a timing chain. Hell, my non tupy head that's supposedly prone to crack is still kicking with almost 200k. All mechanics are subject to fail under the right conditions, but the fact is you're not going to find a ton threads here on timing chain failure.

I just said that, the dude is being an effing tool. Hes an airplane mechanic so it explains alot. You have to be somewhat ocd and narcissistic to be able to work on those.

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!

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.
