    VIDEO - JL JOURNAL : WORKING OUT the WOBBLE - Rancho Front Track Bar Installation

    Like many of you out there with a Jeep JL Wrangler, built up or stock, we developed a bit of wobble in our steering. It's one that mainly occurred when it's cold out and when driving over uneven pavement or hitting something like a pot hole with just one tire. Now, I should point out that what we've been feeling is FAR from being the infamous "death wobble", the violent and uncontrollable shaking of the entire Jeep and to the point where you can only stop it by bringing your Jeep to a stop. However, I can totally see how someone new to Jeeps might confuse it as being death wobble especially being that it does feel like the beginnings of it. Because a loose bolt or worn out track bar bushing is typically the cause something like this, that's where we decided to start focusing our attention. In this episode of the JL JOURNAL, you'll get to see what the wobble we had looked like and how we were able to work most of it out, if not all of it, simply by installing a new Rancho rockGEAR adjustable front track bar. We hope you find the information in this video to be useful.



    I should note that we are by no means suggesting that the source of our steering wobble will be the same for everyone or that installing a Rancho adjustable front track bar will fix whatever you are feeling. This video was made simply to show what we had experienced, what we had tried and ultimately, what got things fixed for us.

    Honestly, I'm really disappointed in the OE track bar being that I'm STILL running an OE front and rear track bar on Moby. Big difference.

    I would start by checking your track bar bolts.

    Thanks for the video Eddie. Iím heading in your direction as mine wobbles when cold between 40-45 mph and it retains a very slight bit of wobble after hitting 50-55. Did the dry steer test and the TB is showing a bit of movement. Thanks for exposing and offering a fix for the rest of us.

    In the video you said the rear axle defaults to the driverís side. Is it designed from the factory like that or did you purposely set it that way, if so why? Iím pretty ignorant when it comes to setting up suspensions so Iím genuinely curious.

    Either way another informative video.

    You have to love it when the fix is fairly easy and on the first try...

    Do you think that contraction of the polymer of the bushings in colder weather is also a contributing factor? Any difference in polymer composition between the two track bars?

    Hi Doghouse, he mentions it because of the arc the trackbar end (bolted to the axle bracket) travels when moved up or down. Drop the suspension in a hole and the track bar pulls the axle to the pass side, shove it up on a rock and it travels to the driver side. In neutral on a flat surface if you lift the vehicle it pulls the axle to the passenger side and opposite if you lower the vehicle axle. As a side note the front is the opposite.

About us
ďwayoflifeĒ is a moniker that Iíve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
