I have searched all over this forum and done all I know to do...Help! I checked all angles before I started and put them all back and still have BIG Issues. (Castor / Camber ,Etc.) My Samurai drove great at all speeds and all surfaces till I did a RUF set up with TT Missing Links up front. Put in New poly bushings and some special bushings they sold me at TT to help with this problem. I put on new  U bolts, Gas Shocks and a HD Monroe steering stabilizer. I am running 235/75/15's on 8 in. Rims. Also put all new OEM steering rod ,Drag Link, Etc. New bearings and seals , Felts , King pin bearings (all set up to proper specs) and I mean everything is done! It rides just like I want and sits like I want but THIS I can't deal with! ANY CONSTRUCTIVE INPUT WELCOME! PLEASE!

You might try swapping out the folding shackles.  They might be adding to much play.  Have you checked to see if your front axle is sitting at a slight angle after the conversion?

It sounds like you have replaced just about everything that commonly goes wrong.   What speed does it start to wobble?

It does not show a hint of any trouble till I hit a Bump and then I almost have to come to a complete stop to get it back. I put in shims to rotate the housing to get it back to where it was before. The shackles are brand new from TT and tight. I did use the stock locating pins in the Leaf springs to get a longer wheel base for Tire clearance later on. Man I am LOST!

I could be wrong, but aren't you supposed to install any missing links
type of shackle on the rear or trailing side of the leafs?  Having a moving
type shackle on the front or leading side of the spring would be like a
shopping cart wheel at high speed, they can get a real bad rhythm going

Any other ideas?

I installed them as the manufacturer instructed. I also watched a video on youtube on them.

So what has trail tough said about this? is there an
issue that causes this that they know of ?

Going to pull out the new Poly bushings that I put in when I installed the Missing Links ,the ones that go through the Frame at the top, and put in solid bushings this weekend if I get time. TT seems to think that it will help. We shall see.....

Let us know how it works out.

by doing the RUF you raised the vehicle height. sounds like to me you need to install a high steer or 'Z' bar. since its because of bump steer. i just did RUF conversion myself and yes it doesn't handle as nice as before but for what it does off road its worth every penny. also install a pan hard bar, that should help a lot. i haven't done it yet so i can tell you, I'm just to busy to do it this summer i have to wait till winter. and double shackles are fine, that's the whole point of the conversion is to get all that droop. another thing i haven't gotten around to doing is, but i am going to be welding angle iron on the anti kick back plate and a tab on the 'y' shackle and nut and bolt it so that the missing links don't move on the road. then when i want to off road i remove the bolt.  but definitely upgrade your steering. i am SPOA with Sky's high steer kit and had virtually no bump steer. i did the RUF w SPOA and have some bump steer now, definitely not a conversion i recommend for a daily driver.

My springs are under the Axel so the Geomertry should not be off enough to do this. After I put the solid nylon bushings in and I still have a problem then I will try your suggestion.

WELL ! It seems that I have solved my problem ! I just took my Samurai for a test ride and the solid bushings from TT through the Frame seems to have done the trick. I will be keeping everyone posted as I get to drive it more. Thanks to everyone for your input.

what solid bushing r u talking about? do you have a link. bc after i did mine its still driveable but there is definitely added vibration.

I called Trail Tough and spoke to a Tec. and he turned me on to these Bushings I have. They do not list them in their catalog but they have them. Give them a buzz and tell them what you want. I don't know the number right off hand......

OK it's back! I have been driving it for a while with no issues then tonight I hit a bump and WOBBLE! W T F !!! I have ordered a drop Pitman Arm so I will see...........

Your Death Wobble is now actually a bumpsteer problem.

A Drop Pittman arm will eliminate it by making the draglink more parallel to the tierod under normal suspension load - which eliminates the bumpsteer problem in a different (but similar) way that an OTT steering system would.
