Death wobble can be made up of many things.....first not having your axel centered under your jeep can cause death wobble...
Sorry but, this simply isn't true. Fact of the matter is, your axle will almost always be off center depending on how much weight you have on board or lack there of. It's just the way a solid axle works and it being off WILL NOT cause death wobble.
...negative caster in upper and lower control arms can cause it
Negative caster can make it a lot easier to occur but ultimately, you would need to have a loose or worn out suspension or steering components to make it happen. Also, caster can be set by either your upper or lower control arms but they themselves will not have any. Hope you understand that I just wanted to make this clear for anyone else reading this thread. :yup:
When I took my 2012 jeep in for alinement they told me that they want to replace one ball joint to correct camber and caster. I have a 3 1/2 inch lift with 35 BF Goodrich tires. I did not want to replace just one so I am waiting during my wait I hit a bump and my jeep started to death wobble only done this once. I want and check all my steer joint only found some play in the drag link. When I jack up the jeep and pry up the tires I notice that the ball joints have a little movement in them the axle shaft move up and down when I do this. I guess my question is and my original plan before all the death wobble started was to replace all my ball joint and replace my lower ball joint with offset ball joints. Will this help with the death wobble? I figure it won't hurt. My second question is has anyone know about moog ball joint are they any good and should I put offset ball joint on it. What other brand of ball joint do you recommend? thanks for any help that you could send my way.
Bad ball joints will cause death wobble and are a common culprit. Moog joints are pretty affordable and will get the job done but, I might recommend a set of Dynatrac ProSteer's if you can afford it. They are pricy but will be the last set you will ever need. Crown HD joints (same as Synerygy and Alloy USA) are a decent option as well. I would also double check your unit bearings as them being bad will create a similar condition and can cause death wobble as well.
