Exclamation '12 Crew Cab Long bed road vibration and death wobble

'12 truck, fully stock 18000 before trip 23000 now.

First question is anyone with the crew cab and long bed when driving on concrete roads (not asphalt covered) seels really rough. The vibration was up and down so it was like the little bump every 10ft or however they pour the slab was being amplified and it was to the point where it was uncofortable riding in the truck. This was mostly on roads in Arkansas, Missouri and Iowa, felt it a little in Texas and Nebraska.


Second one is before the long roadtrip over christmas break I felt the shaking above I was having issues with the death wobble. I would hit a bump and then the standard shaking all over and had to slam on the brakes to regain control. Took it to the get tires balnced (didnt help), Ford balanced the tires and such and it helped some and went away for a couple weeks (also i might not have driven on the freeway much at the time) then Ford replaced the steering damper and everything felt good.
However now that the road trip is done the truck is death wobbling again.
I feel a slight pop or something loose in the steering I think.


Do yall think these might be connected and what all should I try, tell the dealer to check out?

The first issue is not unusual on a HD truck. All my dodge and now my Ford HD bounce on concrete roads. There is a patch of road east of OKC that used to beat me up real bad. The Dodge 1 ton was the worst. I had to slow down over the road. Tried to use it as an excuse not to see my in laws. Didn't work. As for the second issue I don't know. My steering gets loose over bumps at speed especially in a turn. I do not believe they are related. You first issue is a characteristic of the vehicle.

I keep hearing more and more about this. Recently had a friend of ours has 34k miles on his f350 srw and started death wobble. Took it to ford, ford said they couldn't fix it. He also said it would only start if he hit a bump just right, then to get it to stop he'd have to come to a stop then proceed again. So long story short we put a dual shock stabilizer bar on the steering and it resolved the issue.

That is a good solution and I would think have no warranty effect. My steering is too loose for my taste. Could help rectify both function and feel. Does anyone know of a good aftermarket due kit that works with stock ride height?

I know the kit we installed on the truck I mentioned earlier was a pro comp kit and stock ride height.

I have a 12 CCLB F350 and no issues at all. I am running Fox Shocks on my truck with a leveling kit up front.

I havent had time to make it to the dealer yet but i am feeling a light pop and hereing anoise in the steering so my guess it that is the reason the stabliizer went out in 4000 miles.

Where did you get your leveling kit and would that have any effect on my warenty?

My leveling kit is a readylift and it has no effect on warranty that I am aware of.

The dealer even offered to install it for me.

Your pop might be your track bar isn't torqued all the way to 350ft/lb at least that's what's needed on an 05-07.

FYI. Stabilizers really only mask the problem. This is something that began with the 05+ trucks when they went to the coil spring based front axle. I had the issue slightly when went to a leveling kit and then once lifted and larger tires it was really out of control. I also went with a dual stabilizer and the issue went away but after speaking with suspension shops it was explained the stabilizer is really only masking the issue. Aftermarket track bars (sometimes called panhard bars) are made to actually correct this issue (although I still never removed my dual stabilizer so honestly don't know if the issue went away or not). The steering on these trucks is extremely touchy once tires wear uneven or you lift them in anyway throwing the steering off.

You can YouTube ford death wobble and see this has been around for a long time. Pretty crazy still so much of an issue even in the newer trucks

Yeah I knew it was a problem on old trucks. When I went in the first time they dealer service guy said what year 06 when I said 12 his face just dropped. Im thinking tires could be a part of it but it seems to be the front components themelseves have some issues so I was going to try to get them fixed before getting new tires.

I know Carli makes some good componets so I want to get one of their kits. Im just worried about my warrenty. what all would they/could they void if I put on one of their 4.5" kits?
