Question Death Wobble part 2

8,654 mils ago we replaced the front parts
Steering box
Tie Rod with new ends
Hub assembly both sides
(4) new shocks
NOW I have the same shake when hitting a bump.
My wife just had her control arms replaced in her LR3 in Columbia S.C. (dealer)
I can not get on my lift since one of the race cars is getting a rebuild.
Any idea if it COULD BE the only bushings we did not replace?
I have a complete 1995 parts truck so I can rob parts.

Did you adjust the preload properly for the swivel *****?

Those parts need to be replaced every 8,653 miles. Sorry.

Listen this is going to dredge up all the death wobble trolls so let me be the first troll to chime in.

Death wobble comes from one thing - slop somewhere in the front end. I call BS on the whole swivel ball preload thing. Unless there is slop at the swivel pins, no wobble. So solving the issue comes down to finding where your slop is.

I replaced a LOT of things in my front end trying to rectify this situation. Did the preload thing with the fish scale three times and it didn't make a damn bit of difference. Replaced everything around the swivel ball and also had no effect.

So, what did I do? I replaced all the bushings front and back and it WENT AWAY. Specifically, the stack of rear bushings on the front radius arms were shrunken and hard. When I got underneath with a spud (something I suggest you do ASAP) and started prying around on stuff I could move the front around close to half an inch in any direction.

Now, everybody is going to jump on me because they say it says in the RAVE that it is due to the preload. It really doesn't. It mentions NINE other things to check, before a casual mention of "check the resistance and condition of the swivels".

Take a look yourself, page 5 of the Steering section in RAVE, see attachment. Or waste your time with the fish scale barking up the wrong tree. Up to you.

Go right ahead and ban me Disco Mike for disagreeing with you. You have threatened it several times before - now's your opportunity to follow through.

Too light swivel preload as a cause of death wobble isn't BS and it can, in fact, occur even when there isn't apparent slop.
However, it is obviously the last thing to check since to properly check it you need to remove the swivel seals.

So the rest of your post is right, check everything else first, and be methodical.

Correction: Your post is mostly right.
#2 on the list says check the steering damper. That's wrong. For normal everyday driving you shouldn't even need a steering damper. Replacing the steering damper to "fix" everyday steering wobble is just masking the real issues.

Well now, that's right high praise coming from you; I'll take it.

On second reading something jumped out at me:

7. Coil spring vehicles only - If problem persists
fit damper kit STC 241 (2 off front) and STC
1474 (2 off rear). Road test vehicle.

Read that twenty times before but never read it. Hmm... it's cryptic, retro fit damper kit? Is this perhaps an admission to a design fault? I wonder if there is any info about this floating around....dammit now I'm all curious...

Interesting. Not normal for them to provide part numbers in the shop manual, but does anyone actually run OE shocks?
