Is this normal?
 
New to the forum. Just purchased a 2013 Wrangler Unlimited 4 Door. Everything is stock.

Let me preface this with " I'm no wimp when it comes to driving" but,

Coming home from the dealer, while passing a semi on the freeway on the left at 70 (Speed limit was 75) the jeep started swerving left and right drastically. I seriously felt I was going to loose control.

Next I tested the same move at 60. Still did the same thing but not as dramatic.

What I am describing isn't the normal small push/pull when passing a semi. I drive a 37' RV so I am very familiar with that.

This can't be normal. Any thoughts. Really put the damper on buying a new vehicle.

Thanks

-Jim

Welcome! I am not sure if that is normal but if I were you, I would try the same move again while a friend videos you and your JK. A picture, well in this case video is worth a million words, you what I'm sayin'?

Check tire pressure. Is the rig stock?

JimGo 07-11-2013 09:47 PM

Stock. Brand spanking new. Will check tire pressure. I thought about video taping a dealer mechanic test driving it.

Could the front sway bar cause this?

if its disconnected, yes.

welcome to driving a jeep!

JimGo 07-11-2013 10:16 PM

Door says "Cold = 37 PSI" TPMS says 39 and it's 100 degrees here. So I would say tire pressure isn't the issue.

Has ANYONE experienced this with a 2013 4 door?

coelement777 07-11-2013 10:20 PM

This is definitely not normal. I have a 2013 2 door, the speed limit on the interstate here is 75 and i have passed semis going 80 with no issues whatsoever. If yours is a rubicon check the front sway bar first, your not supposed to drive at highway speeds with it disconnected

forgedoffroad.com 07-11-2013 10:26 PM

I ran into that problem once... that's when I remembered the front swaybar links were still in the pocket of the driver's seat.

...and that was on a JKU with 4" lift and 35" tires on 15" wheels, so take it for what it's worth.

Lusus_Naturae 07-12-2013 12:48 AM

You may want to try dropping the pressure to 35. I noticed in summer I have to watch the air pressure a bit more in my tires, I run 29 in winter - which if I leave it alone becomes about 34 in summer. I drop it every summer to 29 or I get some wiggles on these cruddy roads and highways.

A Rubicon that isn't malfunctioning won't allow a driver to do this. It is designed to automatically reconnect the front sway bar at speeds about 20+ mph.

It sounds as if something is inadvertently disconnected.

My '13 Unlimited has no sway issues. I agree that something was not attached properly or is malfunctioning from the factory, and the dealership missed it during "preflight".

Take it In to the Dealership

I agree, I have run my JKU past semis at 75-80mph and never a problem. They have gone by me at 75mph and no problem. Take it back in, there is a problem. Like others have said, a Rubi will connect back up if you go 18mph or higher, just the light stays on until you hit the button.

Lbear 07-12-2013 09:44 AM

As you may have noted, this isn't normal. It could be a defective swaybar or other suspension issues, but whatever it is don't risk your life here. Take it to the dealer and have them find out what it is and don't take it back until they do. The only thing I ever had was the hood ballooning when passed, but no control issues.

JimGo 07-12-2013 10:00 AM

Thanks everyone. Dropping it off at the dealer today.

kjeeper10 07-12-2013 10:43 AM

My guess is alignment. I've heard of issues on new jeeps.

JimGo 07-13-2013 08:01 PM

OK, so the dealer test drove under the conditions I explained, they checked the suspension, torque, etc. Test drove again, and no symptom. I went to the dealer and test drove with the service manager, nothing.

Could this just be a fluke incident?

Anyway, not sure it matters until I'm done with the mods.

I've ordered-

Fox 2.0 Performance ATS Steering Stabilizer

I'm ordering Monday

Teraflex 2.5 Lift Kit
Fox Shock Absorbers
Front Remote Reservoir Mounts
JK Monster Trackbar

I wanted the Toyo Open Country AT's but they are on big time back order, so I'm settling for the 35" Cooper Discoverer A/T3's

For Rims I like the Ultra Maverick 17". Part Chrome/Part Black

Any pro's or con's to my choices?

lando76 07-13-2013 08:12 PM

Dang, JimGO you trying to jumpstart the economy single handidly?? :)

The teraflex and fox shock combo are great. The jk monster track bar is not necessary with that set up and will provide no real performance gains, unless you are dead set on adding it. From a quality standpoint it looks like you are making some great choices...have fun!

kjeeper10 07-14-2013 08:48 AM

Nope.. Prefect. You will like that setup. My option on the track bar, is its nice to have over the weak factory Tb. Nothing wrong with having the axle perfectly centered either.

ahsumtoy 07-14-2013 09:26 AM

See what happens after
 
After you put everything on, make sure you have it aligned again and then see if you have the problem.

My only advice - make sure the problem is solved before you start the mods. Otherwise, the dealer can easily say it's not their problem.

kjeeper10 07-14-2013 11:10 AM

New track bar/steering stab, and maybe bumping the caster up to 5* should help a bunch.

JimGo 07-14-2013 05:00 PM

Told the dealer service manager what I was doing (worried about the warranty also) he said that most of the Mopar lift components are made by Teraflex for them, so he would have no problem honoring the warranty with the setup I'm doing.

Thanks guys

boon4376 07-14-2013 05:32 PM

Hey Jim,

I noticed that the jeep tends to wander a lot more than other vehicles I've owned... Not enough to seem out of the ordinary, but it's not as tight as a sports car. Granted, I'm used to driving saab's and subaru's with very tight, twitchy steering. I think what you are experiencing could be normal, especially due to the lack of aerodynamics.

JimGo 07-14-2013 06:48 PM

Hey Boon-

Yes it does wander. This wasn't a wander, or the normal suck and push I experience in my RV when I pass a semi (or they pass me)

I've owned a lot of different vehicles in my 42 years of driving. Porchse, Vette, Truck, Large SUV's, Street Rods, etc. Nothing like this has ever happened to me.

The wife grabbed the scare bar when this happened, and I was close to out of control.

Don't know what it was, but I DO NOT want to experience it again.

Ashumtoy- Alignment - That's a definite.

JRussBlues - I'm on the fence on this. But after watching the video on Teraflex's website showing the flex of the stock Track Bar, it kinda of all makes sense. It's the only thing centering the axel, and I can only describe what I felt as "The Death Wobble"

The dealer said the "DW" usually happens around 40 MPH. I was doing 70.

Interesting, my dealer said it was AEV.

Lusus_Naturae 07-15-2013 05:04 AM

It could have been a fluke. I had my TJ in for work years ago, nothing big, replace a shock and balance the tires. I got it back and headed to work, on the highway. I only got down the entrance ramp half way before I got death wobble bad. I was able to let it coast down to 20mph and I limped it back to the dealer thinking it was related to the new shock or tire balance. Everything was ok. They took it out a tested it while I lost 2 hours of work. I got it back and it never did it again, making me wonder if it was related to letting the axles droop while the shock was exchanged.

He wouldn't be willing to put that in writing would he? My father was an attorney who always said an oral agreement isn't worth the paper it's printed on.

Wheelz 07-15-2013 10:48 AM

I'm assuming you had them on, but by any chance were your doors off? I've noticed in my JK (as well as my old TJ), when passing a Semi, or getting passed by a Semi, driving at freeway speeds, you really feel the strong gust of wind. It almost pushes you out of your seat sometimes if you're not expecting it. I've had a similar feeling with just the top down too but not as bad.
I'm guessing it was more of a perfect conditions type of moment. The wind may have just hit the right spot and really pushed you.

JimGo 07-17-2013 06:14 PM

Wheelz- This wasn't the normal push pull of a semi. I am extremely familiar with that driving a 37" motorhome. Doors were on. This wasn't a push. It was the front end out of control.

Good news is, parts have started arriving.

Received today-

Teraflex 2.5 Lift Kit
Fox Shocks
Fox AES Dampner
Teraflex Hinged Spare Carrier
JK Monster Front Track Bar
Cooper Discoverer A/T3's

Waiting for-
Teraflex Rock Guard Epic Front Bumper
Ace Engineering Rock Sliders
Wife to give the thumbs up on wheel choice :)
