front end probs
I have a 99 f350 that is having a serious front end problem! The main problem is that it will not happen for the dealer. While driving on smooth roads, no bumps or anything the front end will start , what I call hopping. It is so bad that I will have to pull over and stop. This will fix the problem until next time. The shimmy is so bad that the truck can not be controlled. any Ideas?
We have had the truck in for the same problem at least 6 times. We have had lots of parts changed a steering stabilizer add and new brakes new tires you name it.
Truck has about 135000 still in great shape but I am afraid it is going to kill me or some one else

Only other thing that I can think of with my limited knowledge would be a bent rim. My 93 Explorer blew a radius arm bushing and that caused a bumpy ride but also a loud clang every time I hit bump. Hope you figure it out, I'm sure some other folks will be along with more ideas later on in the evening.

I have seen this once before while I was in the military. On the some of the front ends of the chevy diesels we drove the ball joints coupled with loose tie rod ends caused it to shake and shimmy all over the road. I am no mech but that was the reason I was given.

that would make sense but these too were replaced.
Here is the bad thing. With no problem showing itself at the shop the Mechanics have no idea where to start so they won't.
What is going to happen, maybe tommorrow, they will call for me to come and pick my truck up after making minor adjustments and 1,2 or 5 weeks from now I will be in Construction traffic as only nashville has and I will mess my pants. (not really)
This is funny, When I dropped my truck off the guy tells me "you know, there 1000's of these trucks on the road but only a few have this problem" then he continues and sayes " you should see your truck from the outside when it is happening, the wheels are jumping off the road this much (holding his hands about 8" apart) You would think Ford know they have a problem.
Don't get me wrong I love my F350 but i am getting scared of it. God knows I will not be hauling a load with it and that is why I bought it
Thanks guys

Can we consider "lower control arms" ??? bushings.. I'm not that familiar with the front end of the truck, but found that was the case with some cars with that many miles on them. Exactly same conditions.
I may be way off base on this suggestion, but am submitting it anyway..

I had similar problems. If you have the original steel wheels they sometimes are or get out of round. Often more pronounced when changing tire sizes, etc.
Go to a reputable tire shop and have them pull all four wheels and tires again and have them "road force balanced". They spin balance at a moderate speed and apply a force to the tire and wheel simultaneously.
Typical standard protocal for most tire shops is the standard spin balance. Didn't help my problem.
Went back for the second time and they decided to "road force balance" them and that fixed it.
You have to ask for it and they will probabaly charge more, takes a bit more time, but cures mine.
Hopefully that's all it is with your PSD.

I have what sounds to be the same problem. Does yours seem to do this more under braking? My truck is also a '99 350 dually with new shocks. I think that balancing with a load could prove interesting since braking from about 45mph seems to have a negative effect. I will post updates as I continue to resolve the problem.
