Did you even check out anything else? To make sure that you weren't covering it up? Alignment on it or anything? You can throw a hydro ram on something and not have any wobble too. Doesn't mean you fixed a damn thing you just nerfed the feeling of it. Shit it's a 3 min process to check all the steering joints and suspension joints to make sure you don't have a come back and fix it right the first time and not have more than one test drive bc it waste time and money.

I turned wrenches for over 6 years professionally at a dealership doing everything thing from rebuilding rear ends to some body work(screw that by the way) and I know you fully diagnose a problem and get to the root cause not fix the first thing you see, then find more problems.

You're putting misinformation out there bc you and I both know it's a damn band aid. I was in shock and appalled you even mentioned a stabilizer will even fix it. Look up steering and suspension geometry. Again, no disrespect by any means but I think you need a better understanding of steering/suspension geometry.

Edit: you still didn't answer my question of you check the suspension/steering components, with or without the stabilizer installed.

Dougzin I'll weigh in here with my small but growing amount of knowledge. I know a lot of my issues revolve around my jeep being severely out of alignment. I wheel my jeep hard every other weekend at least. Eventually I'm going to knock it out of alignment eventually. I know my heim for my track bar has quite a bit of play and that my tie rod ends have seen better days. Once I get all that done ill let Y'all know if it cures my death wobble.

Ditchdoc Ok I'm going to shut up now and make some boritos.

Ditchdoc If I remember right I think it's called harmonizing force multiplication and that is a damper works so well on eliminating it because a dampener prohibits the harmonizing of the unsymmetrical motion amplification.

suicideking I'll also throw in to have your tires balanced. I had some wobble starting a while back and my tires were way out of balance.

GY MTR are known for being difficult to keep in balance.

Cured or hidden?

Ditchdoc Gee, and all this time I thought death wobble was cause by unsymmetrical travel of the track bar and steering link and this may sometimes act as a wave generator causing the wobble. Bleh who needs physics.

I definitely need to plus up my tools, I have just enough to get me by. But it sure would make my life easier if I had all the right tools. What I do now is pin or clamp the box wrench down then find a place to push against with my feet while pulling the torque wrench. One day I'm going to punch myself in the balls. I think that 24" breaker bar would save my manhood.

First thing I looked at was the steering stabilizer, which had rock damage. Test drove it, one of the worst cases of DW I've driven. Replaced the stabilizer, drove like new. No need to look at anything else with that low mileage. That customer has since brought it back for complete suspension and requested the Fox ATS stabilizer because his first experience made him a believer in having a good stabilizer. When we have a case of DW now, it's (1) check stabilizer and replace if necessary. Test drive. (2) track bar and all related components, replace or repair as needed. Test drive. (3) Ball joints, check and replace as needed. To this date, we have never had a DW problem we couldn't fix by using this method.
To be honest, after I blew up my stabilizer on Achey Breaky, I ran without one for nearly 3 months until I got around to buying a new one. I have stock steering with high miles, never once in that time without a stabilizer did I get death wobble or even a slight shimmy. I noticed a slight increase in bump steer, but that was it. I did put it back on because it does serve a purpose, but I severely doubt that a bad stabilizer would be the cause of death wobble. By that logic I should have never been able to get above 25mph without my teeth shaking out of my head. A stabilizer's only purpose is to reduce bump steer. If other components are out of tolerance then that bump steer causes oscillation in the axle, aka death wobble. Fixing death wobble with a stabilizer is analogous to fixing a pipe leak with duct tape, really expensive duct tape, sure it will stop the leak for a while but the leak is still there and will need to be plugged eventually.

Stan what's the purpose of that stabilizer/dampener? Do you check all of the steering with the stabilizer connected or disconnected?
And how come I've ran without a stabilizer for well over a year and never had death wobble till my TRE went bad? It's a jk with apparently over 5" of lift bc some guy tried to tell me my frame couldn't be as high as it is, and no control arms to get the caster in spec. Can you explain that?

That and steering head bearings.

Speed wobbles @ 100mph on a dirt bike in the middle of the desert.... Scariest moment of my life.

I might have even pooped a lil... Just sayin.
Today 07:25 PM
Gunner Well it is proper for a race bike so you have quick turn in on the corners. But on the long straights when you wind it up then the geometry is compromised for high speed. Then the damper comes into play. Some of the very best ones are tunable on the fly depending on your part of the track.

Lol so I've heard but with proper geometry you wouldn't have to worry about the dampener like you said.

I've torqued everything on mine before it's not that hard man. Even if you just do German torque specs (good-n-tight) and use big boxed end wrenches, 13/16 fits most of it, or a 21mm. Most the jam nuts I use, not factory stuff, are 1 5/16". That's for my rear control arms, what will be on my new 1 ton steering, and track bar.
