...Tomorrow add the drop bracket and balance tires-if that doesn't fix it drive it into a tree.
Patience grasshoppa...
So are you driving it every day, then working on it every night? If not, then you're giving in to frustration way to quickly. I know you're kidding about the tree (maybe!) so I'm just kiddin' back, but still, just wanting you to not get too mad at it too soon. Plenty of other stuff to do yet.
And frankly, day before yesterday was the first we've heard anything about a wobble. You didn't mention that in the first post about it not handling well. So until you said that, nothing we've been trying to help you with has had anything to do with wobbling.
Sometimes of course, if you fix one thing, you fix another. Not always though, with Broncos!
Wobbles, by their very nature, come from the tires. Nowhere else.
Yes, a loose component, such as a trckbar or ball-joint, etc., can "let" the wobble happen, but the wobble itself is coming from the dynamics of the large black heavy rubber rolling thingies attached to each end of the axle.
Is it truly a wobble though? Or more of a shimmy? Heavy shimmy, or full blown wobble? Subtle differences sometimes, but still different.
Shimmies are often tire balance or unevenly worn tires, or incorrect air pressure. You're on the right track in having them balanced then. Especially since it sounds like a speed-dependent shimmy that can be driven out of by increasing speed.
Here is something though. Have them balance all four tires. That way, if the shimmy/wobble still exists after this, you can try rotating your tires front to rear to see if that changes it. You can do that no matter what, if you want, but it might be better to do it later so you can determine if it actually was an issue with one particular tire or two.
Tires, even new ones, can have a bad or damaged internal belt that will give you a true Death Wobble (not the incorrectly labeled crapload that Ian on Xtreme 4x4 talked about today!) that will shake the steering wheel out of your hands and usually can't be stopped until the vehicle slows way down.
Doesn't sound like what you're talking about, but interestingly enough, a real Death Wobble can loosen and wear out pitman arms, trackbar bushings, ball joints and rod ends. Some of which you've already gone through.
Definitely get that trackbar angle dealt with before you drive it again. It's just too far off. You might have to re-adjust your trackbar again, since lowering it changes the length requirement, but that's easy enough to do.
So hang in there a bit longer before the proverbial tree-hugger in you comes out to play! ;D
