Epic, I read over in TDS that Rancho told a owner that the truck had to be raised 2" for this kit to work. Do you think there will be a problem with my stock truck and this setup? Also what about this notching the adjusting arm on the drag link? Can you take a picture of your passenger mounting spot in detail so I do it right?
So I did do it and notched the drag link but left that part out of the video. I didn't want to perpetuate an out-dated install guide.

I ordered my Rancho dual steering stabilizers Wed night and Fed Ex dropped them on my door Saturday morning. Busy all day Saturday but was able to sneak out before church this morning and install them. Finally went for a drive tonight - found every pothole and bump I could find.
Wow what a difference...no wobble over bumps or potholes. Firmer steering - which I like and the truck should have from factory.
Of all my mods this one and the speaker upgrades are probably my least amount of money and best money spent.
Baseline for everyone:
- F350 CC FX4 Camper Package (1 up on front spring) Michelin 18" LTX/AT2
- Bilstein 5160's - reduced the rear end bounce/firmed up front end (OEM Ranchos are pathetic)
- 2" lift (increased the "bounce steer" - almost dangerous)
- Did alignment & positive castor (eliminated bounce steer - then I started to notice steering wobble)
- Installed the dual steering stabilizer Rancho RS98510 --> problem resolved!!!
The truck no handles like I want it to - "supposed to"...
Again thanks Lexustbs for ID'ing wobble and Epic for problem solving!!!

Do the new Rancho's put up with the noise better than the old ones??

The only thing I questioned was why do Rancho instructions say the tie-rod clamps need to be tilted slightly forward??? I did tilt mine, but I don't see any potential interference. Is this some sort improved stability geometrics issue?

Confirmed on my install you do not have to move the adjustment sleeve nor do you need to "file" a groove for the u-bolts on the tie-rod ends...the tie-rod ends actually have a little bit of a "block" casting chape and the u-bolts and bracket fit perfectly around this with no movement possible.

I'd have to get a measurement of the dampner point of connection to the tie-rod arm with the bracket in "flat" position to center of wheel versus the install of the dampner brackets tilted forward.

(of course compare this estimate with the reason Rancho gives back to Epic

Warranty Issue
<HR style="BACKGROUND-COLOR: #d1d1e1; COLOR: #d1d1e1" SIZE=1><!-- / icon and title --><!-- message -->I had the dreaded "Death Wobble". I found a place I could reproduce the "wobble" at will. It was a manhole that was about 4 inches below road grade and I would hit with my left tire. This is where I took the Service Manager for rides.
I put my truck in the dealer's shop the first time and they replaced the front shocks and said a nut had "loosened". I'm assuming the nut was on the ball joint for the track bar. They said the front shocks were dead.
Several months later I took it back in with complaints of the front end bouncing too much. They replaced the front shocks again.
On the drive home I still wasn't happy with it. I called the dealer and got the number for - THIS IS IMPORTANT, SO PAY ATTENTION - ask for the number of FORD CUSTOMER ASSITANCE and file a formal complaint. I called them and they opened a ticket on my truck. I took it to the dealer and left it for a week.
The Ford engineers came onsite and were in charge of all repairs.
They replaced the front shocks with upgraded factory certified Rancho 5000s. They also replaced the track bar and ball joint, along with the steering damper.
This DID fix my problems and I am happy with my truck again.
They also tested and replaced my rear shocks, they said they were weak. This eliminated the bounce I was getting on concrete highways and was not part of my complaint, but I sure am glad they did it. I was ready to pull the trigger on a Firestone R4Tech airbag system.
Before I took it in, I talked to Steve at WC Motorsports about their track bar solution - $825.00 - parts only.
But the item of note is he said you can't run BFG All Terrain KOs on these trucks - which I am. I have standard size with 18" rims. I noticed if I ran 65lbs in the fronts it would bounce like crazy and the Death Wobble was easy to reproduce, but if I put 70-75lbs in them, no death wobble. I did report this to the Ford and their response was, you should be able to run any tire of the right size on these trucks without issue.
Now I am running my BFGs with 65lbs and have no issues.

Makes me feel good that I didn't need the engineers to get a solution. Lol. Can't they get ahold of a GoPro? :-)
I guess over time we'll need to keep our eyes on the trackbar ball joints.

Warranty
I will say I was getting desperate and was getting ready to dump a bunch of money in it. Then my wife started nagging about the warranty and I caved. I'm glad I let Ford deal with it, now I know exactly how to deal with it when it is out of warranty.

I just have a hard time spending money to fix my truck when it's under warranty.
