What I can tell you is that it is possible for your stock stabilizer to blow a seal and loose it's oil without looking like it's been damaged. Trust me, I have seen it. And, if this were the case, then your stabilizer would look fine on the outside but not work very well if at all. Need I say, this would be a time when replacing it is not a band aid.

 

If you knocked your steering wheel alignment out of whack on the trail, this will have been caused by something being bent and or damaged. I would check your drag link for any impact marks and/or control arm or control arm mounts for damage as well. If all those look good, I would check your steering box where the pitman arm attaches to the shaft. It took a while to find, but this is ultimately where my bend had occured and I know of at least on other person where this has broken clean off. Unfortunately, it is a weak design and one prone to bending and breaking.

 

I hate to chime in on this as it's somewhat controversial, but I believe in a good quality SS and always have anytime you put larger tires on. The tires make the steering react differently and the stabilizer assists in the additional stresses. You can call it a band aid, but I added a Superlift SS to my JK and it is amazing the difference in control now. The alignment was confirmed correct prior and the new tires definitely made a difference in the driving quality. It is perfect now, it's a joy to drive on and off road! I've never had an ESP issue though before and after.

 

Can you go into more detail for a couple things: 1) What made you decide to go w/an aftermarket stabilizer, were you having steering issues of some sort? 2) Can you expand on what the difference was before and after?

I ask because I don't really think I have any issues w/mine as is, but to be quite honest, I've never been impressed w/that dinky little stabilizer up front and wondered if I'd see any benefit in 'feel' with little bit heavier duty one.

 

The Superlift Stabilizer also gets the stabilizer shock up and out of harms way. That's the biggest benefit IMHO.

Perfect point, the mounting is great with the Superlift SS. The stock one to me seemed like there was nothing there, it probably didn't need it prior to the larger tires. But with larger tires every bump is magnified because of a stiffer sidewall, there is no wander or bump steer at all from rough roads.

 

Hello list
I have an Unlimited Sahara 2.8 CRD diesel with a TERA budget boost.
After 9000Kms of super nice street and dirt use ( one Jeep Camp in the pirenees and many trails) it developed a short death wobble after a bump doing 75km/h (about 50mph). The front end had not been aligned after the BB.

I checked all the front end and found the SS all dirsty with oil. I have the tyres filled with 2,5 BAR or air.

I was going to wait for the 10000KM check but last week going 90Mph on the highway, I had a violent death wobble episode. Then after 10 miles while driving carefully at 50 it repeated and I nearly crashed into the side of a truck.

I stopped at 2am and called of my GURU friends. I ended up lowering the pressure to 1.9 BAR and then did 500 miles back to home driving carefully up to 55 miles per hour without the death wobble repeating.

I have two other wranglers both heavily modified and never has a DW before.

Questions:
1.- WHAT IS WRONG IN TH JK DESIGN THAT MAKES IT SO PRONE TO DW?
2.- ANY PICS OF THE SUPERLIFT SS? I need one ASAP.
3.- WHAT DO YOU CONSIDER A JK PERFECT WHEEL ALIGNEMENT?

Thanks
Eduardo

 

Here's the best shot I have of one showing how much higher it mounts. Granted this is a D60 axle under a JK but it mounts the same on the JK D44 or D30.

I guess I`ll add my two cents.I just added a Rock Krawler 3.5" mid arm lift complete with adjustable front/rear track bars with brackets,adjustable front/rear upper/lower control arms.Since my lift, I`ve noticed some bumpsteer and going around corners(especially on/off ramps)my ESP/BAS activates.BTW-it was sent to an alignment shop immediately after the lift install.Although I had my lift installed,I checked all my control arms for proper length.So even though everything seems normal,I believe with the higher center of gravity,You still have additional stresses placed on your steering components and this IMO translates to erratic steering and bumpsteer.I also believe a stouter SS will remedy this.I know when my older Jeeps started to have steering issues,aside from alignment and wheel balancing,a new SS always seemed to refresh the steering.
As a side note,I did replace my stock rims about the same time as the lift with new ones having 4.75 backspacing.I didn`t replace my 32" m/t`s, but I think,and I could be way off,that the wider stance makes the JK track differently and with the new suspension and all,I feel that the computer reads all this as instabillity and activates the ESP.If you had a SS that helped reduce if not eliminate all shimmy and bumpsteer,then you would bring the ride quality closer to stock thus aleviating the sensor issue.I honestly don`t see how that puny stock SS keeps any of the steering in check.
