Death Wobble

Anyone experienced this? I've always had it a little but this weekend I was pulling a 30ft camper at 65mph, hit a bump and I literally thought the frontend was going do self destruct. I ended up in the median.

Have you had this issue before, while pulling that trailer?

The issue is always there, just never as bad as I experienced this weekend. I do seem to notice it more when pulling a trailer....maybe because there is slightly less weight up front or that the rear is squated.

That's what I was getting at. Maybe you should try a WD hitch when pulling that trailer . The 05-07's have an issue with DW, and taking weight off the front will amplify the severity. I don't know if they have it fixed in the newer ones, but that could also be a way to 'fix' the issue, as the front ends are pretty much the same. Maybe that's a way for us all to repair the problem. I have it in mine too, but its not too bad, and seemed to be better after the leveling kit. Caster angles will also affect this, so bigger caster cams are available through some of our vendors

My hitch has sway bars...which I think is a weight distributing hitch. Looks like the National Highway Traffic and Safety Board has investigated this a few times....NHTSA Action # PE07057 and EA08007. Ford said it was incorrect air pressure but also issued TSB 07-10-10. I'll look into the caster cams...I think that is addressed in the TSB. Thanks for the info.

You can solve the "death wobble" with dual steering stablizers.

how do you hide a problem like that? It either does it or it doesn't right?

That's good. FWIW, Ford has done all that stuff to mine, that was listed in that TSB, with the exception of the caster cams. Let us know what you end up finding on this issue, because I'd like to fix mine someday

Hey I have an 02 250 4x4 that had a death wobble. Always seemed to happen when puliing my gooseneck horse trailer. Took it in for alignment. Had the front end gone through by the "best" truck people in town nobody found anything wrong. So I put the dual stabilizer on, didn't help. Finally one day it go so bad I was scared to hit the highway in it with the trailer so I pulled into tire discounters and had them look at it thinking I might be wasting my time. The old guy said it was my driversside u joint that froze up. He replaced it never had trouble again. I know the front ends are differant on the trucks but worth looking into?
