Lemon law, buy back truck issues

[John Cooper]

Go to this website and give this place a call. They should be able to help you or at least steer you in the right direction. He has extensive videos on YouTube about Powerstrokes and only works on them.

His shop is in Buford and I am sure he has ran across this issue before. I have watched some YouTube videos of the death wobble and it is a scary situation.

Thanks for that link. As a 6.0 owner I have it book marked now. There is alot of great info on there.

I did a search on death wobble and found a vid from the specialist in Buford. He used a kit from CD or CB Diesel to give some adjustability to the caster. The kit is about $230 plus installation that would probably be another $150 to $250.

When I was involved in SCCA racing it was common on certain cars to slot the suspension mounting holes to gain adjustability and I bet the same could be done in this case.

It's crazy that Ford hasn't provided a new set of trailing arms with the holes moved to provide some additional caster.

I would also like to add that, IMO, the only fix is additional caster. Since Ford is resisting this fix the PO's options as I see them are-

1- Get Ford to buy it back. Probably not happening without lawyers.

2- Live with it. Foolishly unsafe.

3- Fix it. Anywhere from $0 to $500 depending on your own personal drive.

I'd trade it in and get a chevy but will that stuff show up on car fax?

Mine starts 95% from hitting a pothole or something. But one day I could make it wobble by just holding the wheel to the left just a touch going down the highway.

I have a '99 model f-350 that does the same thing. It's parked for now. Some have said camber can fix the issue? Mine already wears the tires out on the inside before the tread wears out

if both tires are wearing on the inside, that is probably a toe in issue

I wonder if these trucks have lift kits on them?

 

[rayjay]

I watched one video where they had the camera mounted on the underside of the truck facing back to the front axle. When the truck hit the bump you could see that the rebound of the suspension definitely changed the angle of the front axle further reducing the available trail.

Also watched videos where they added some more caster and fixed the issue. It's not rocket science. Fix it.

 

[NE GA Pappy]

don't these truck have a solid mount point at the back of the trailing arm? So, if you hit a bump, and the tire moves upward, that should increase the caster? I am trying to work this out in my mind.

 

[rayjay]

Rebound. You hit the bump the body goes down. Then the springs push it back up. Up beyond where it started. Then it starts shaking. The tires are then scrubbing causing a drag on the front that could keep the front elevated. Have you ever done a burnout with a line-loc ? As the rear tires push against the locked front brakes the front of the car wants to lift up.

 

[rayjay]

You could also lower the rear pivot and gain extra caster that way. Gaining it at the axle probably is better.

Another thing is the rubber bushings at all 3/6 mounting points. They have a bit of give.
