Ok this morning running 75 mph big truck on my right and four wheeler on my left I come across the end of the bridge, I see a small pothole. Can't miss it, hit the pothole with the left tire my 08 F250 4X4 started shaking so bad I couldn't hold it.
fortunately nothing behind me, the truck was shaking so violently I thought the front end was going to fall off in the middle of I75. I had to slow down to 30 mph to get it to stop shaking. I have had this happen before and I replaced the OEM steering stabilizer with a Rancho last month. I hope there is something more I can do to stop this next time another vehicle might be behind me when I slam on the brakes. I searched for death wobble and can't find it for the F250s can someone help me?
So I75 is in just as poor shape down south as it is up north. well, OK.
I travel quite a bit back and forth into Michigan, and see Semi tractors loose contact with the road in this one particular spot. there is a caved in concrete slab, it's like a ramp. then I watch the truck drivers cuss in my rear view. you'd think something like that would be fixed right away, but no, it's been like that all summer
I added a dual steering stabilizer when I had a F350. I don't know if it helped since it was preventative in my case. Take a look at this thread for more info. https://www.ford-trucks.com/forums/8...est-brand.html
They just finished grinding the surface and paved it, but at the bridges that are at an angle to the road there is a little of the old pavement not repaired that is what I hit this morning. I read the link to dual stabilizers and I wonder why I would need two since the Rancho I have is double action (resistance each way) I'm wondering if more is going on. The truck only has 155k good tires 80 psi in them (recommended pressure) I'll check the rod ends this afternoon but I'm thinking the castor could be off or maybe adding to it?
I lowered my pressure to 65psi and replaced the steering damper and ask 4 shocks. Made a huge difference. But also need to replace my tie rod ends. With the engine off, turn the steering wheel back and forth 2-3 inches, do you hear any clicking in the steering?
Steering stabilizers slow down the oscillation from left to right. That's their purpose. If one isn't enough, a second one or stronger one should help. Other than costing money, I don't know of any disadvantage.
Obviously, if you have loose/worn parts, you should adjust/replace those parts.
I would highly recommend checking all the components of your front end, or having it looked at by a shop that knows what their doing.
I just recently had the same problem with my 09 F350. You didn't specify how many miles were on your truck, & if all the other front end parts were OEM.
My truck was doing the same. I have 217K on my truck, & all of the front end parts were stock OEM. Just got it fixed, drives like a dream again. I replaced, drag link, track bar, track bar ball joint, axle U-joints, & stabilizer.
My point being, every scenario is different but, can't imagine a stabilizer fixing the problem. The problem is more than likely, other components are worn out.

My truck makes a clicking in the steering box when I do this. It does however drive real nice with no wandering and has no death wobble at all.
Ok I found my problem I think. Took crowbar and pried and pushed everything under my truck. Found tie rod ends were bad,on 157K replaced them last weekend and no problem so far. Thanks for all the help!
