      What is Death Wobble?
      Death wobble is a violent, uncontrollable shaking of your entire Jeep caused by extreme oscillation of your front axle. This is NOT to be confused with a vibration or even a "really bad shimmy" in the steering wheel. The later would be a common problem associated with tires that are out of balance. If you're not sure if you have death wobble, I can almost guarantee you don't. Experience it once and you'll know for sure.

      Common Causes of Death Wobble?
      FRONT TRACK BAR:
      Death wobble is a condition that can occur when you have loose or worn out suspension and/or steering components. The most common cause of death wobble is a loose front track bar bolt, worn out track bar bushing, a failing track bar mount and sometimes even a track bar that is physically bending or flexing. If you've just come off the trail and now have death wobble, there is a good chance your front track bar bolt has worked itself loose and re-tightening these bolts to 125 ft. lbs. may be all you need to do to fix it.

      BALL JOINTS:
      The second most common cause of death wobble are worn out ball joints. Unfortunately, the factory ball joints contain components made of plastic that will wear out quickly especially if you're running much larger tires on wheels with a lot less back spacing. Also, these components are susceptible to heat and can melt if you fail to remove them prior to having C-Gussets welded onto your front axles end forging.

      OTHER CAUSES:
      For the most part, the only things that are found to allow death wobble to occur are problems associated with a front track bar and/or ball joints. Other loose, worn out or damaged suspension and steering components can allow it to occur as well but, they aren't as common. Now, there are a host of things that can help instigate or trigger death wobble and the most common of these are tires that are out of balance. The rythmic shimmying of unbalanced tires will put a strain on suspension and steering components and can easily work bolts loose. Left unchecked, this additional movement will eventually compound and be exaggerated until it results in death wobble. Other things noted that can instigate death wobble include a toe-in setting that was drastically off, a caster setting that was significantly less than the factory +4.2 and I have even seen where one front shock that wasn't valving properly trigger death wobble as well. But again, most of these things cause the wearing out of components and/or the loosening of bolts and once that occurs to something like your front track bar, death wobble can ensue.

      Steps You Can Take to Fix Death Wobble:
      1. GET YOUR TIRE BALANCED:
      Getting big off road tires balanced is hard to do and it's not uncommon to need 2-3 visits to get them on right. Even if you've had them balanced recently, I would still recommend that you do it again before proceeding. While unbalanced tires will not "cause" death wobble, they can instigate it and, if they are still off, it will make it harder to identify the actual source.

      2. SET YOUR CASTER:
      You ever get a shopping cart at the grocery store with a bum wheel? You know, the kind that wobbles all over the place even though you're going straight. This occurs because for whatever reason, the wheel in question has very little to no positive caster on it. Likewise, a Jeep with little to no positive caster can instigate death wobble as well. Lifting a Jeep will effect your caster and it is important that you have it set as close to the factory +4.2° as possible. Having more is better but, that can cause driveline vibrations and that's not something you'd want to have.

      3. REMOVE YOUR STEERING STABLIZER:
      Because a steering stablizer will dampen movement in your front axle, leaving one in place will make it difficult to locate the actual source of your death wobble. Removing it will cause your death wobble to occur more consistently and more predictably and that'll not only help you to find the source of your problem, it'll help you to know it's actually fixed.

      4. CHECK YOUR FRONT TRACK BAR:
      Wheeling is hard on your suspension and steering components and having a bolt come loose on your front track bar is very common. More times than not, re-tightening your track bar bolts to 125-130 ft. lbs. of torque is all that is needed to fix death wobble. If your bolts check out, carefully examine the bushings and mounts for signs of cracking, tearing or fatigue on both the axle and frame especially if you have a relocation bracket that is not reinforced installed. The added height of a relocation bracket can act as a lever and over time, can cause your weak factory mounts to fail through metallurgy. Some will suggest that you also check the mounts for any signs of wallowing of the bolt holes and if they are, they would recommend that you have a plate or washer welded on to tighten things up or, install a new larger diameter bolt to help make up the difference. However, torque is what is imp

      Chrysler has taken steps to kill the so-called "Jeep Death Wobble."

      After several hundred complaints were filed with the National Highway Traffic Safety Administration (NHTSA) by Jeep Wrangler owners who experienced a severe vibration in their 2005-2010 model year vehicles, two members of Congress from California urged the company to address the issue, which it has now done by issuing a technical service bulletin (TSB) that recognizes the problem and suggests several ways to fix it.

      Make sure both the power steering lines; pressure and return - are replaced at the same time as the new steering pump. Consider as cheap insurance for the system.
      It is possible you have a defective steering pump - but before removing and replacing the pump, first check the system very thoroughly for leaks; loose hose connections,etc.

      Do you not have a regular repair shop that you have used with
      confidence & good results for years?

      When you go to the highway--chain store places their job is to sell you
      something,not necessarily road test your vehicle & take you along &
      try & find a problem & then a solution

      Unless you had a damaged wheel (bent) or ONE Bad Tire--then your problems
      would be more likely in a worn suspension part

      No amount of alignment will correct that or the wobble

      So do not be so gullible you believe the tires are or ever
      were the issue--I doubt they were

      If the problem is so bad you have to slow down or it is that unsafe
      why are you using it for a year & yet again back to where you have
      to start over

      The Answer is--go to a quality shop
      Spend time explaining why your there
      Go for a road test with the mechanic along & you driving

      Authorize nothing & buy nothing until they can prove to you
      what the REAL Problem is

      Aside from the tires a year ago-you did not say what else was done
      Those new tires were not a fix,even for a year

      If in your many years or decades of driving you drove 4 to 6 years on new tires--
      why would you get sucked into a situation where you believe anything your told
      that wasn't in your years of experience with other vehicles?
