I have a 2010 F-350 and have noticed the same problem. At first I thought it had something to do with the cruise control. I would be cruising, trailer or no trailer, dump the Cruise Control, and nail the gas to pass cars. It would go into a violent shake.
I thought it was axel wrap, weird at high speeds, so I added Pro Comp traction bars. Again the violent shake would happen when hitting the gas. So I really started paying attention to the gauges when this would happen.
This is what I noticed.
Driving down the road
Hit the gas
Truck would down **** x2 gears, resulting in RPM's rising to 2500.
At 2500 truck would start to shake
Boost maxed out
All truck temps at operating temperatures.
Backed off gas, letting the truck shift into the next higher gear, shake stopped.
So then I tried to get the truck to shake from a start. Tried this when truck was just started (cold). Then again when truck temps were at operating temps. When bringing the truck up to speed, driving normally, truck got up to speed without shake.
Tried again when truck was cold, this time hammering on the gas, no shake.
Again tried when truck was at operating temps, hammered on the gas, no shake.
Third attempt was after driving 45 minutes, (did this several separate times). When hammering on the gas, truck would shift into 3rd gear and at 2500 RPM'S, with boost about maxed the truck would start to shake. Letting off the gas stopped the shake.
i too thought this only happened when driving up a hill, in humid or rainy conditions. Not the case I believe this is a combination of boost being maxed, RPM's at 2500, and truck running a touch hot.
At the time the truck (engine) was stock. FORD stated the DPF was partially clogged. Somehow the dealership unclogged the DPF, they reset the computer, reset the transmission, retrained the transmission, and no more shake. The only thing negative from this procedure is the truck was constantly going into "cleaning exhaust system, continue driving". And I mean every single time I started the truck.......
I brought the truck to a local shop that "specializes" in 6.0 and 6.4 Fords. They stated that running in a stock mode with the combination of truck running warm, boost levels up and 2500 RPM's the truck was starving for air, resulting in the shake, input of more gas and no climb of speed or RPM's. Installed cold air intake, H&S (running mild), DPF delete. No more shake no more "cleaning exhaust"
I think it was luck that fixed mine, but just waiting for it to happened again. What else have you guys noticed on your gauges when this happens? What is boost at, what gear, what RPM's?
