Ford 6.7L Power Stroke Diesel :: Driveshaft Shudder With Goose Neck - Airbag?
May 5, 2014
So I picked up a 53' for the racecar. When I'm hauling it on take off I'm getting a pretty good shutter out of the truck. My crew chief who owns a maintenance shop, said it's a known issue, and ford has been shimming the drive shafts.
I talked to the service writer at my dealership and he said it's a known issue and they are working on it. However, he said if they shim the driveshaft, there is a good chance it could fix the problem loaded, but then unloaded I'd have the problem. Is there a setup that's recommended?
I'm towing about 15k, but that's far from the limit of my 450.

Truck has just over 5000 miles on it. Had the tires road forced, no luck! Took it to the dealer ford said replace the tires 2 at a time (r then f), picked it up yesterday no better and said that ford wants to put a new driveshaft in it!

Every time I start the truck, the Passenger Side Airbag light is on, which is saying the airbag is turned "OFF." I have to push the button to turn the light off, which turns the airbag "ON." How do I reset this to where the airbag is "ON" until I turn it "OFF?"

So I have had this happen 3 times so far. As I am driving, and step on the accelerator, I get a very bad shudder in the engine. The whole front of the truck is jumping up and down. Once I slow down it stops and is fine.
It has happened on the following three occasions but it is intermittent and does not do it all the time:
1. driving up a long grade at 45 mph for 5 minutes. I stepped on the accelerator to speed up and it happened.
2. Getting on the highway from 45 to 70 fairly quickly.
3. Once I got on the throttle heavy and got up to 80 MPH. I laid off the throttle to slow down and when I stepped on the accelerator again it happened.
I was not towing at any of these times. I do have warranty still but since I cannot always replicate it, I have not taken it to the dealer yet.

The past month or two, my garage-kept 2011 F350 6.7 with 38K miles will shudder on startup for a second or two or three then runs normal. What would be causing that? She is my every day driver, but I don't drive her every day. Seems that the longer she sits, the rougher the startup. Last time I drove her was Monday. Started her up tonight to run to the store and she shuddered for about three seconds.

So my 06 6.0 4x4 is just about to break 200,000km and I've done most of the upgrades and work myself. (All the updates are in my Sig). My problem is that when I'm cruising and the engine is at full operating temp, if Im bellow 80-100km/h nothing but as soon as I break into that speed range about 2000rpm the truck will start to shudder. Almost feels like its not firing properly is the best way to describe it. Why this could be happening or causing it?

Anything besides a worn out Torque Converter clutch that might cause the incredible amount of shaking when the transmission tries to lock the TC?

Recently had a rear pinion leak and replaced the seal and nut. I jacked up the truck, took off wheels and felt the drag so I could duplicate once i had the new seal as I tightened the nut. I've done this only once before on my F150 years ago, but when I put the driveshaft back on and test drove it, i had shudder when not under load. So when I let off of the accelerator, it had shudder and more the faster I was going.
Obviously thinking this is a preload issue with the rear axle but would this be caused by tightening too much or too little. I had no issues before so I would think that the driveshaft itself is not the issue. I can't confirm that I got it bolted up in the exact same manner as before in relation to the flanges but still wouldn't think that to be the issue.

I bought my f 350 new from the dealer and have had many of the problems associated with this truck. Now I have a severe shudder while under acceleration when i either let off the gas or increase speed the shudder goes away. My dealer thinks it is injectors but I have little faith. Shudder seems to be rpm consistent and seems to be in the front end. oh yea it idles great and runs great except at that specific range.

While I am loving the fuel millage and ride of my new truck, I have my first concern. In the last few weeks i have hauled a truck bed full of dirt, and 3300 lbs of sod. both times i would use tow haul mode, and while the truck had plenty of power, it would shutter when accelerating from a stop. Mostly first gear 0-15 mph.
This is my truck with a fancy electronic controlled transmission, so on the old pickups this would be a torque converter slipping, but all the ford dealer wants to tell me is "its electrical and they want to reflash my transmission". I am at 26k miles and have less than 10k left on my warranty...

Truck had been running with a bit of a skip and shuddered after throttle was applied and then stopped (would drop to 400 RPM and shake real bad). Had some misfire codes so I decided to do some digging. Where to start looking for air leaks pre upper fuel bowl?

Also, does this mean the air has toasted my injectors?

I have already logged 6K miles on her, crazy, but it's my job. I have pulled 5 maybe 6 trailers (form trailers, about 15K pounds loaded, this time of year). Loaded or unloaded, when I push the throttle in 2nd, 3rd gear, I feel a shudder, like transmission shudder.I know this thing throws down 800 ft. lbs. of torque, should I not be pushing it so hard? Or, what am I feeling?

2006 long bed with LS diff sometimes gets a fairly robust CLUNK! sound and feel when decelerating with tow mode engaged. It only happens once per 20 trips and only about a mile down the road, and it only happens once in a blue moon. It definitely is the rear end making the noise and brief shudder. Otherwise the truck runs extremely well.
I had the pumpkin off and fluid changed with Ford friction modifier added at about 100,000 miles. Truck is at 160,000 now. I just got done with a trip in the mountains of Idaho carrying a truck camper and used tow/haul mode extensively for engine braking and climbing, worked like a champ. This was just one trip of many this summer. This is about the only thing wrong that happens on my truck, but usually occurs before I get very far from the house. Should I just forget about it?

I've done the testing of hitting the brakes when the TC is locked and when it's off the shudder disappears. My question is I recently had a trans flush and both internal and external filters replaced. There was a hint of noise before then but it seems it's getting progressively worse. Could it be that they used the incorrect trans fluid? Reading through it seems as if I should follow the steps of dropping the pan and looking for signs and symptoms and then replace with the correct mercon fluid (if that's not already what's there). Then maybe some additives like shudder fix? I just want to make sure I take the correct steps to solve the problem as to not break the bank getting a new TC put in and missed something cheap and easy. Also reading it could be motor related maybe a misfire so just looking for pinpoint the problem.

I have a 06 6.0 no start . I was at a light felt a slight shudder went to take off felt another shudder and it just died. Changed fuel filters, unplugged icp no start still. No code at first now throwing p2291. Fuel pressure is at 62 when cranking. Hooked up air to the icp port and only heard air coming out of both valve covers inlets. Ipr was at I believe 60 to 65% when cranking. Little back round 2 years ago I did the whole sinister diesel top end kit and put the updated parts in. New o rings on everything that took them, new egr valve, standpipes and dummy plugs. On the injectors all new o rings and crush washers. I believe that's everything.

My airbag light is on and I don't have a clue what to look for. Recently had body off, but I've checked all my plugs and all looks good. No codes relating to airbag in the memory.
What's the airbag checklist?

I purchased my 2013 F350 PSD July of 2014 and immediately noticed "the shudder" when the engine was lugged down to 1000-1100 rpms on a hill. Sounding like somewhere around the turbo belching air too. At first I was startled but learned to manually downshift to higher rpms and it will stop. Once or twice I tried accelerating out of it and it shuddered as bad as the poster who said it made the steering shudder too.
My truck has 16,000 miles and I never let the rpms drop now. So I figure I have a real problem I'm not imaging. What should I tell my dealer is the TSB or remedy ?

Late build 03 f350 auto, I got a p0500 code and noticed sometimes after 2rd-3rd gear engages theres a shudder or fast vibration for few secs unless i let off, it didn't start this till i took batteries out, where is the location of the vss at, I am seeing some say at each wheel, on top rear diff, on top back of trans so not real sure?

Finished my install last night for my airbags. The passenger side looks good as far as alignment top to bottom, but the drivers side is tilted pretty good. I lined up the alignment pin in the upper mount as the instructions indicated into the most forward hole and there is no way to move the lower mount because it is up against the leaf pack tight where it belongs and the tabs on the lower mount does not allow for it to be turned on the axle housing. I believe it is out of alignment enough to cause excessive wear and or improper performance (the rubber part of the airbag is actually touching the lower metal disc that is part of the airbag when there is no air in it).

2011 F250 Fx4 diesel. I'm pulling a 14' GN dump trailer. My truck squats. Should I go to ford and get a quote to put the overload package on or put in an airbag system? I want to put a on-board air compressor in for air chuck use and louder horn.
