Death wobble

Just think, they're going to start putting vibration dampers all over the place next. We'll see them start appearing on drive shafts, exhaust systems, transmissions, engines and all kinds of other things.... oh, the horror of it, a driver and the passengers actually feeling the engine running or hearing some resonance through the drivetrain.

Oh, wait, they've already done that.

really, this is a fact, is it?

so then whay are the steering stabilizers still on the power steering equipped Toyota vehicles with solid front axles?


i guess for looks.

looks like this thread has the dreaded "death wobble"!

[crushers]

i guess it needs stabilizing then, eh?

actually, it needs key components removed and replaced.


adding a stabilizer would be like clicking " ignore" on certain posters.

Well put and right on the money.

This may well be covered in the 40 series link but I don't care enough to look.

I had the problem quite badly in my lifted BJ70 and now have a theory.
Sprung under trucks with lift springs tend to have this problem more. It is actually aggravated by a good stabilizer when it is connected to the frame. Jeep solved the problem on the YJs by adding a ridiculous panhard bar to a leaf sprung vehicle. Toyota owners can solve the problem by moving the stabilizer (or better yet hydraulic ram ) to the axle.

As a point of reference with respect to geometry and stabilizers, my badly engineered, sprung over BJ74 on flatish springs, has no wobble at all in spite of having no stabilizer and about 5 degrees of positive caster.

In any situation where a lift spring is used and a longer shackle has been installed, you will need to correct your caster angle. Adding a few degrees over the stock factory angle is a good idea. Have it measured at an alignment place and then correct it to around 2.5 to 4 degrees.

hth, John

Hmmm....

Stabilizer in it's stock location deadens impact that would otherwise be hammering the sector shaft/steering box...isolates much of the impact to your tie rod/drag link ends...cheaper and easier to replace.

To the original poster, your pics show the drag link angle is fairly steep...will cause bump steer as previously mentioned. IME pitman arm from a PS equipped 60 series has 1 - 2" more drop and should help.

Anyone know of any "good" landcruiser shops in the Lower Mainland??
Specifically for deisels and for custom work??



(and of course front end /alignment issues)

[TwoThirtyDirty]

Never used them but popular opinion seems to be that these guys are king...
