the fix for the whine is a total rear end rebuild...from what i read....which is proly why Ford has not issued a recall....too $$..plus a recalll is only for safety or defect issues...this willl not kill anyone....just annoy us all.....

 

Desert Heat....

What I did (if it makes a difference), I actually waited for the
tech and drove the car with him and reproduced the problem.

He recognized it and later call me to tell me what he did........

Hopes this helps, or maybe you already done it this way.....

Good Luck to you!!!

 

Same problem with my 2002 (24000 miles). I've had it to the dealer twice but it never does it for them. I keep hoping something breaks, then they'll find it. Dang truck

 

I recently purchased an 04 as well, and have the same vibration problem. So far the I've had the 4 tires changed out...no change. They (the dealership) recently force balanced the 4 wheels with their fancy new machine that allows for the balancing with the tires and wheels mounted to the vehicle...a marginal difference. I especially have problems with towing. I'm only towing approx 2000 too, and the vibration at 60 mph is so bad that it's keeping me from towing! I bought the truck largely so I could tow easily. Now they've stated that it might be in the drive shaft, so that will be next. I'm sceptical and believe it is in the rear end (wheels/shocks). Even when I hit uneven surfaces the rear end wants to 'bounce'. Any and all insight is appreciated.

 

My dealer replaced tires and balanced all before I picked up my new truck just two weeks ago. I'm now noticing a shimmy, rattle, shake in the rear end. Its Baaack! Not good!

 

I have an 02 with 41k mile and it to whines with light throttle between the 45-55 mph range but not to bad at present.
With a lot of time on me and mechanics, I believe it is a problem in the rear center section assembly.
A whine is a fast occurrence fault like a ball or roller bearing with a flat spot or even a ring/pinion fault that, at the right speed range, gets amplfied and transmitted through the frame to the intensity that you can hear it but it's really there all the time at less intensity.
A friend's 3 ton Chev dump truck even has a sing the same way when I go with him pulling our race car on trailer.
Only way around it is to bebuild the rear paying close attention to every detail by the mechanic.
The factory could very easy use a transducer and indicating meter mounted on the rear to see the whine come in at the speed range and be done with the fooling around trying to decide what to do.

I just got my truck back and the dealer put in a new driveshaft and tailshaft. They said it was "out of round".
Whatever, the vibration is gone and my SCrew feels like new again. Thankfully still under warranty for this repair.
