check your exhaust pipes for clearance issues, it might be rubbing somewhere like the downpipe for example, if nothing there you may also consider checking the 5 bolts that hold the turbo down. You need to just poke around a bit or give more detail describing your vibration.

I've experienced the same situation with both my '03 and '05 F350's (6.0 with a torqueshift tranny). The vibration only occurs under a high load, and then only for a few seconds.

My '08 F450 also does it occasionally, but less often. However, the '08 has 4:88's, and the F350's had 4.11's, so there is less loading on the '08 tranny.

Based upon my experience, I would not worry about it, but would be somewhat gentle in 1st gear).

You may want to try greasing the slip yoke. I had almost the same issue with my 06, and greasing the slip joint on the rear shaft fixed it. There is a write up in the tech folder on it.

sounds to me like you overloaded a little bit. I think you are having a pinion angle issue causing it. been there donr that.
can you move the forklift back on the trailer a little bit and take some weight off the toung. That may help.

I have a vibration from initial take off. I took it to the dealer and they said it was my carier barring. The height of it needed to be adjusted so the vibration will go away.

thats what I said. droping the center bearing down will drop the driveshaft down and change the angle.
simply repositing your load may do you just as much good.

Cheez,

Wasnt there a bulletin on this issue for some of the SD trucks and they had a kit with shims or something. I thought it was LWB trucks with the 2 piece drive shaft?
