Michel347 So many variables, with the aligment, tires, ... For me it felt strange when I got my Cherokee back in 96, for the fact that I was coming from individual suspensions to two solid axles. But it didn't took long to get use to it. I kept it until 2006 where I went to an SUV with independant suspension. I also felt strange at first. Now I'm back to solid axles with my new JK 2dr, and I love it. I like the way that it's handling.

Even with its short wheel base, I'm not feeling that it is more affected by cross winds than my previous 4x4 or even the Focus of my wife.

JerryJeepster My 2 door is straight as an arrow. I do however get to enjoy the typical 2 door shuffle.

Seems like Chrysler should pay attention to some of these forums, as it seems a few bad apples from the factory are giving Jeep a bad reputation for handling, or at a minimum making a bad reputation worse. I realize it's not a Porshe, but that doesn't mean you shouldn't feel safe driving down a paved road with it.

Weight helps sometimes.

kjeeper10 Caster makes a huge difference. The spec range is I believe 3.7- 4.7.
That being said, somebody with 3.7 is going to have worse handling then somebody with 4.7-5

Also a 2 door will handle worse then a 4 door with short wheelbase.

My jeep had a slight pull left when stock. Went away with the lift/adjustable lower CA's

BigMike47172 I replaced a 17 year old Explorer with a JKU Moab edition and I find the highway ride to be very comparable to an Explorer. I think Jeep could sell even more Wranglers if they pitched it as a replacement for people who don't like crossovers.

cnhmatthews My '13 JK 2 door requires a little work to keep it in a straight line, but I just put that down to the steering system. I don't think it'll ever be as smooth/precise as something with rack & pinion steering. It's kind of fun to feel like Fonzi driving on a TV show constantly "sawing" at the wheel. I notice it more when I drive my wife's car. My Jeep drives fine, but it takes more correction than anything I've owned before. This is my first Jeep so I just accept is as part of its personality.

Reece For what it's worth; I got my 2013 2 door about 5 months ago. I started out with 40 psi in my 18" wheel upgrade from the dealer and I was all over the road. It scared me on the way home. A simple avoidance maneuver almost sent me off-road but not in a fun way. I checked here and lowered to 30 psi and drove with the TPS light burning bright but much more manageable on the highway for about 2 months. Then I raised the pressure up to 35 psi. The light went out and I'm still driving straight. I think it had to do with tire pressure + the learning curve. Changing vehicles requires learning the new "feel" until it becomes automatic. I don't have any problem now, at any speed. Heavy cross winds can still be a little dicey but that's just the nature of the shape and side profile.
05-14-2013 09:16 AM
kjeeper10 Perfect... The caster is not going to be the same. It's almost impossible.
You could try adjusting toe out a little to 1/8 in

You are at the lower end of caster overall but shouldn't be a problem and won't cause a pull.

Have you checked your brakes. Maybe a caliper is sticking ?

Edit: control arms or cam bolts adjust for caster.

BacaraJKU No mods and stock tires. Good idea on having them swap tires with another jeep to test the issue.

FL FR
-0.5 Camber -0.4
3.7 Caster 3.8
0.10 Toe 0.11
12.7 SAI 12.3
12.2 Included Angle 11.9

Front:
Cross Camber -0.1
Cross Caster -0.1
Cross SAI 0.3
Total Toe 0.21

RL RR
-0.4 Camber -0.2
0.18 Toe 0.05

Rear:
Cross Camber -0.1
Total Toe 0.22
Thrust Angle 0.06

Everything is within spec I would say right down the middle. The guy said they like to see caster on the front the same, but it requires adj ball joints. However mine is within 0.1 of each other and that wouldn't cause this issue I'm seeing. He said based on Thrust Angle I would go to left if anything.

Also, I'm about 200lbs and I've tried the "put a 200lbs passenger in the car as well" idea.

Just hoping this info can help out OP and myself.
05-14-2013 06:22 AM
slsbl77 go with 32 lbs in the left front and 34 in the right front. Make sure toe in is correct, if you want to keep the lift, get the AEV Geometry correction brackets. If these measures fail, see the multiple posts about LCA's

When driving on the interstate and let go of wheel now, it just drives right on over to right. Alignment is within spec and was told if anything my thrust angle would push me to the left. Only other adjustment I can make is adj ball joints to mess with caster.

I wanted to nail this down before I do oversize tires/wheels. Fighting with Goodyear to get new factory tires, but they won't cover a full set at this point. So my options are, keep take offs and put new set on, then see if problem goes away. If it doesn't, it's a factory issue and I get to try and prove this with jeep. It's tiring driving for 3+ hours and holding the wheel constantly to the left.

Might look for a cheap set of factory tires only just to see what happens. It's becoming my biggest annoyance right now.
Rotate tires front to back or swap tires with a friend. This should rule out the tires.

"Adjustable" ball joints are used to correct camber that's out of spec.

Stock toe in and steer straight are the only adjustments.

Do you know your camber/caster specs ?

Do you have any modifications ? Some manufactures have the lengths of their lower CA's longer on the right. This is to keep the jeep from following road crown.

If it's a possible warranty issue the dealership should put a set of tires from another jeep on to rule that out. I would ask or uh tell them to do that.

I love how my 2012 Jeep JKU Sahara looks, the features and capabilities.

I absolutely HATE how it drives.

This thing is hard to drive in a straight line without constant steering input/correction. This wandering can be exhausting on a long trip. I traded a BMW X3 for the Jeep and now I'm looking to trade the Jeep for an X1.

I know it's a Jeep and they are different but what I can't understand is how Jeep sells a vehicle that is really not meant for highway driving at normal Hwy speeds. Sometimes, in windy conditions it even feels scary to drive. God forbid you drive with one hand only while holding your coffee or changing the tunes. Before you know it you are on the other lane or hitting the rumble strips.

The Jeep has a Teraflex 2" budget boost, and 33" tires.

What can I do to improve the handling/steering of this beast? Steering dampers? Magic? Voodoo? Is it even possible?

Thanks for your input.

I'm sure I will get some people telling me it's a Jeep or is a Jeep thing or just live with it because it is a Jeep, please don't.

I'm sure I'm not the only one with this problem, most if not all know what I'm talking about. Don't be shy, its ok, you too call vent about the poor handling.

My girlfriend refuses to drive this thing as she thinks it is unsafe.

Please be kind with your replies.

Go back to stock. I have the stock wheels, and have no issues. Long trips on the HWY= very comfy. I am also coming from a full size gmc truck.

DJL2 If you do go back to BMW, go for a 3-series "xi" wagon. An all around more capable vehicle than the X-series unless you're wed to the idea of sitting higher off the ground for really no reason at all. =)

macbazzr Maybe I was one of the lucky one's, but my 2012 JKU Sahara (with stock rubi wheels & tires) is a pretty smooth ride - much better than I ever expected in a Jeep, especially after reading forums like this. I've had several cars in the past, including M3's, and was prepared for the worst when I drove the Jeep - but to my surprise, it tracks straight and even corners fairly well (as long as you don't hit a large bump mid-turn). Actually I prefer the ride to my M3's, especially when it comes to potholes and road bumps - hardly feel them in the Jeep - and I'm running all 4 wheels at 40psi. Of course it's loud with those tires, but nothing you can do about that. Check your alignment and look for bent or warped rims, and consider swapping out your tires. Ride quality should NOT be an issue with the new JK/JKUs as long as you're running reasonably stock suspension - and don't let others tell you any different.

OffRoadWarrior I shouldn't post because this is going on and on. But IMO the handling is normal. Having driven many solid front axle Superduty's, the Wrangler drives and drifts around just like a mini F350. I think it's just the nature of the beast.

Comparing to an X3 with IFS, sport suspension, and sport touring tires, I'd expect it to handle great on public roads (and suck off road.)

My YJ was fine at highway speeds too, as long as my highway speed was about 50mph. After that it was exciting (and, yes, hella loud!) It was never the handling though- just not fast enough to outrun the semi trucks.

The TJ was a great improvement in both guts and handling on highway.

I feel that the JK is even better by a fair stretch. I will say though that when I took a JK for my first test drive, one of the reasons I decided to go with the JK rather than another TJ was that I was surprised how much it still felt like a Jeep and not completely tamed yet.

I would definitely have the Jeep gone over to at least make sure you are getting a fair evaluation of the platform. You might also try test driving a few others.

One question to the Rubicon owners out there- I know that I originally (TJ and JK) wanted a Rubi for all of the capabilities but when faced with the cold hard truth about the many thousands of miles of highway between me and Moab....I had just come to the conclusion (via hearsay and reviews) that the highway manners of a Rubicon wasn't going to be worth the trade off for me. (Personal choice obviously). Is it possible that the OP might take a better liking to a Sport or Sahara?
