Bone stock.

Still wondering why almost everyone's ignoring the steering stabilizer.

What am I missing?

Shouldn't it at least be checked to make sure it's not shot?

Because a stabilizer is not needed to prevent death wobble. If everything else is good, it doesn't wobble. My FJ40 has no stabilizer and does not wobble. Often they just cover up another problem.

Mine only has a couple thousand miles on it max. At least in my scenario I'm certain it isn't the stabilizer.

Install Slee adjustable panhards front and rear with new bushings and have the panhard lengths set by going to a good alignment shop and getting the thrust angle measured.

The other thing you have not mentioned is the lower knuckle studs. Those should be checked, properly torqued, and replaced if necessary.

I'm having that problem with my 60 at this time, any disruption Ie. potholes, bumps on the road will get it started, and I have to come to a complete stop.

Does your version of Death Wobble do this: steering wheel shake back and forth and doesn't diminish even when you're slowing down? And the frequency of this thing seems to go up and down based on speed? When you look at the wheels, you wonder how in the HELL can they dance like that?

I see that no one mentioned birf housing preload. You might as well do a front end job with all new bushings, bearings, races and torque everything down to spec. As someone stated earlier, it's a combo of many things but aging suspension parts is a large contributor. Tires type/size/wear only accentuates the underlying problem. Marlin has a complete kit for sale as well.

Good luck.

lets baseline your suspension bits and pieces and see where there might be an obvious omission that you might have over looked.

Since you have the Slee 6" springs then the obvious included pieces are:

Slee's front control arms
Adjustable front and rear panhard bars

While there are a plethora of other bits to the full kit these would be the main items concerning your death wobble.

So Cody, you DO have these on your truck, RIGHT?

Nope, and nope.

The control arms are just beefier, and push the front axle forward (since lifting it naturally arcs it closer to the vehicle center).

The adjustable panhards simply center the axle from side to side (since the stock panhard is a fixed length, and the front axle is pushed out to the left (DS) when lifted).

I've seen folks with the full Slee 4" and 6" kits complain of death wobble as well...so while those parts center the axle better at the raised height, this is definately a something is loose, not pulling in a direction, or binding reaction.

I just can't locate a loose or damaged part that would allow the violent wobble.

I did do a full front axle service, and everything is greased properly, torqued to spec, and all bearings and seals are factory Toyota replacement parts.

There is no noticeable play doing the tire push pull check when off the ground.

I'll go on record here and say I don't think you will ever find a loose or worn suspension component for your death wobble and expect a third such thread entitled "death wobble III, broken thumbs"

Geometry is off...

you really need to fix the caster correction, panhards and any angles that need to be addressed due to the lift.

By not having these, it's probably exaggerating the issue even more.


Why wouldn't you want a better driving cruiser? I honestly can't think of any reason NOT to fix the caster and panhards...unless you want to end up in a ditch and go topless 80.

They arms also fix the caster, small detail but important.

True, but right now your front and rear axle do not track behind each other. This is normally not a good thing, especially at 6"

Show me one person that has our full kit installed (also used correctly, ie with weight as it is designed so the lift is what it is supposed to be and not exagerated due to extra height gained with no load) and complain about death wobble?

You have massive tires on the components that they were not designed for. Ignoring the basic suspesnion geometery is not good. These tires will bring out any anomaly.

[landtank]

unfortunately I'm thinking that by now those ridiculous tires have a wear pattern that even if he were to straighten out the geometry the wobble would still be there to some extent.

[badmuthatrucka]

I'm probably way off, but when was the last time you had an alignment done on the old girl? With the way you drive that thing, it couldn't hurt to have someone take a look at it.
