New JK owner

Hi all-
I just recently purchased a 2016 wrangler sport s unlimited. I traded in my 2007 jeep liberty which was a money hole.. Always needing repairs. I bought the wrangler because I have previously owned yj and tj. Both great vehicles , no major repairs. I hope the new wrangler will be reliable and good for trail rated activities. My concern is all the DW situations, which not only sound horrible, but should not be a part of a new car owner 's experience! Is this something to be worried about in 20k miles?

Welcome to JKO!

The answer to your question is, it depends. Do you plan to leave it stock? If so, I doubt you will see any DW issues until many miles, perhaps 100K, but that is just a guess. If you plan to lift it and go with bigger tires, then yes, DW becomes something to think about.

From my personal experience, the two leading "causes" of DW are tire issues and front track bar issues. The holes in the front track bar brackets can become ovaled out. This will allow movement in the track bar and allow DW to happen. There are two things I do to every jeep I own or help lift. Install an aftermarket front frame side track bar bracket and the proper 9/16" shouldered high strength bolts for both ends of the track bar. For whatever reason, Jeep makes the bracket hole 9/16" and then shoves a metric bolt in it that does not quite fill the entire space. This allows movement, which is a bad thing.

Synergy makes a nice frame side bracket. They also include a new 9/16" shouldered bolt. However, it is course thread and I prefer a fine thread. You can go to a decent hardware store and buy 9/16" shouldered fine thread bolts, I think you need about 3 or 3.5" in length. I would replace the stock track bar bolts with these. That will reduce or ever prevent the ovaling of the holes and eliminate the single largest source of DW, IMO.

Thans for the welcome and heads up! I do plan on keeping it stock while under warranty. Will installing a non oem trackbar void warranty? Alsi I will try the bolt upgrades!

There is NO reason to install an aftermarket track bar. The track bar is NOT the problem. Its the damn bolts and weak ass frame side bracket.

Chrysler has redesigned the bushings in the track bar several times. They are more durable and designed for the suspension and handling of the jeep.

Changing it can bring new problems you don't need. Just add the bracket and change out the bolts. Done.

Search for '"Planman's diagnosis" or try this -----> http://tinyurl.com/94coqqg


Your post doesn't totally make sense to me ( context) but if you've a stock suspension & maintain it at correct service intervals as-well-as check your rig after wheeling it, the much over-used term of ' Death Wobble' should be easily avoidable for you ..... Watch the videos in that thread and don't lump "DW" into an overgeneralization of 'poorly designed setup ' or 'improper service ' as seems to occur ....

NOT downplaying true "DW" but for a new Jeep owner planning upon keeping a stock suspension to be obsessing about death Wobble' is a bit of testament to how much misunderstanding there exists on the subject ......

<edit: I apologize for not saying ," Welcome to jkowners !" & also any assumption on my reply ....are you inquiring because you plan to lift ,etc?...>

Thanks for the welcomes and extra info. I do not plan on a lift, but did read a number of posts about DW on stock and relatively new vehicles.. With little sucess in fixing the problem. Truth be told, a new $30k investment should not require the owner to do anythjng outside of normal routine maintenance. Anything else suggests poor design/ engineering from manufacturer.
NoI have no plans to go rock crawling. Just want to have a dependable, reliable jeep.

You are right, but truth is any vehicle with a solid front axle is susceptible to the dreaded DW. When you read about people not having any "luck" resolving DW issues, it is usually because they are counting on luck to resolve it. They read crap on the internet and then assume that is what the problem is on THEIR jeep. When in fact, each DW situation is different and each requires a thorough diagnosis. Someone pointed you to Planman's thread, videos, etc. Truly a wealth of information on how to diagnose DW. If you want, I can point you to some threads over on Pirate4x4 that will truly bend your mind when it comes to DW. A couple of suspension engineers got into a heated debate about the causes of DW. Its a fascinating read, but at the end of the day, its all theory and has little practical application.

IMO, jeep did indeed make a mistake when they spec's the track bar mounting hole at 9/16" and then installed a metric bolt that is ever so slightly smaller. And it being fully threaded doesn't help either as it acts as a large file to grind away at the bracket. Put a true 9/16" shouldered (smooth) bolt in there and you just fixed what I have seen as a common cause of DW in our JKs. It is annoying that you need to do this on a new vehicle, but it is what it is. It is Fiat Chrysler after all..................

Thanks for your help. Again, it seems that the responsiblity to make such upgrades shoukd not be on consumer, but rather on manufacturer. Especially if solution would save them money overall. And again, for $30 K anyone shoukd expect things to work properly. My days of tinkering rather than driving are long past. If I were to spend say $4k on a vehicle, then I woukd be prepared to spend time working on it.. Just sayin...

And the wrangler and other jeeps are advertised to be rugged.. They should live up to their heritage, which they so readily use for sales pitch.. Again I hope to have a rugged reliable vehicle. My 07 liberty was a disaster. I dont wish to repeat that experience.

I was just trying to give you some fairly easy "insurance" things you could do if you wanted to lessen the chance of DW. If tinkering is not your thing, then just drive it. As long as you leave it stock, keep the tires in good shape and balanced, you would be fine for many, many thousands of miles.
