well I went into work this morning and finished the steering stabilizer i've been working on (didn't have to change as much as I thought from my original attempt yesterday). So far I've only built one for the passenger side but plan on mirroring it onto the drivers side. This has taken care of my steering shimmy between 40-55. But has made me realize that something is still wrong. The steering wheel no longer has back and forth play, but vibrates between 40-55. But it's not just the steering wheel, its just more noticable in the steering wheel because the shaft ties to the rack/pinion directly on the frame where everything else in the cab is dampened a little bit by cab mounts, seat mounts and other such things. I believe I may have a defective tire, but thats another thread. I'm adding a link to some pictures of the completed stabilizer asm (passenger side only thus far). Clearance on it is good all the way around and accounts for full suspension movement without binding the bushings on the stabilizer. I used some RS9000 15in closed and 22.5in open (already had these). These happen to hit the bottom the same time the steering does. I'll probably get some shocks that are 14in closed and 21 open. It only needs 5in of travel but 1in on each side allows for the X factor. I'll try to answer any question. This design will only work on the drop suspension but a similar design could be used for stk and prg'd titans and armadas.
here's the link

i'll add more pics mon or tues when I add the other side.
