Shudder When Accelerating
My '05 FX4 SCrew has a shudder when accelerating from a dead stop. The dealer says that "it is not bad enough to try and find, just keep driving it and see if it get worse". I don't particarly like that answer.
This is not the "clunk" or "bang" that some have when accelerating from a turn or after slowing down, it is only when you start from a dead stop.
It is not a motor shudder because if you powerbrake the truck to about 1500 rpm there is no shudder at all.
Any thoughts from anyone?

if you have a limited slip differential then I would venture to guess that it is the LS cluth packs shuddering. Mine did it too, the harder I launched (or starting off with heavy load) the more pronounced it was. My dealer also told me it was not bad enough, and then told me it was vibration from my Bassani exhaust.
I went to another dealer and they replaced the LS clutches and it has been smooth-as-silk ever since.
