I have the same problems and they can not fix it. they have replaced the drive shaft, put a shim between the leaf spring and axle and installed a "dampner" what ever that is and nothing has helped. I am now waiting for new transmission mounts. 10 days so far. If it is not fixed the next time in I am going to start lemon law process. Does any one have experience with this?
I also know the BBB Autoline will help.

Mine is a '04 F-150 4x2, but I get exactly what you describe. It feels like its coming from the rear-end. I haven't taken it in yet. Did the replacement work?
#832 of 2180 2004 F-150 shaking
Dec 20, 2004 (7:07 pm)
Folks, over the weekend a thought occured to me. All of you that have the new F-150's with the shaking - have you altered the shape/aerodynamics of your truck in any way? Have you added a topper, bed cover, truck box, etc.....
The reason for my questions is this: Years ago I had an '82 Toyota pickup that I bought used. It would shake violently at any speed over 40 mph. Since the tires were old, I thought a new set would fix that. It didn't. The tire store told me that the tires weren't the problem, but that all five of my rims were bent - yeah right. But bought new rims anyway. Guess what, didn't fix the problem. About a week or so after that, I decided to take off the topper that was on it because I didn't need it. You'll never guess what happened. The shaking went away.
All I could figure out was the topper altered the aerodynamics enough to cause serious wind flow issues with that truck. I never had another shaking problem with that truck.
I said all that to get to this - If you have put something on your truck and it is shaking, you might try taking it off to see if the shaking goes away.

Yes, I do have limited slip rear end. They did replace the differential clutch pack, and on my "request" showed me the Service Bulletin 04-24-2 which referenced several symptons including the pronounced shudder on acceleration from a stop on turns (my problem). The bulletin also stated in bold print that they should caution me not to tow anything for 500 miles. Of course the guy who replaces the clutch pack reads this, but the service advisor who hands you back your keys doesn't necessarily pick up on it. I think I'll always make it a practice to ask to see TSB's in the future.

So far so good. No more shudder.

Glad I could help. The Piston Slap was kind of a long shot. Your truck was the right year for the problem, but according to the official Ford line from back then, Piston Slap was only exhibited in first the 10-12K miles. If the noise didn't show up by then, then the engine was fine and would never develop it. They replaced a whole slew of 5.4 and 6.8L engines early on, and then the issue just faded away. Guess there's an exception to every rule.
I'm glad Ford stood behind its engine, though considering this was never an official recall, it makes wonder how bad they messed up on the design originally that they still take responsibility for it at 70K miles. Sounds like they've been seeing the problem resurface in older motors and are trying to nip it in the bud.

I had the same problem with my FX4 took it in and the they adjusted the clutch in the differential, the truck feels much lighter on take offs.
#837 of 2180 Lost 1 vibration, got a NEW one!
Dec 22, 2004 (9:35 pm)
My '04 Lariat Supercrew 4x2 had a 40-50 mph vibration that was corrected by replacing the driveshaft. I was so happy, I put a set of 2" lowering shackles on the rear leafs. Right away I noticed a harshness or shudder type vibration on take off. It's most pronounced between 15-25 mph, then smooths out. Is it possible the new shackles caused a u-joint or driveshaft alignment problem, or is this a rear end problem? It sure seems similar to the vibration others are describing when accelerating from a stop or turning a corner.

I bought my 2004 in June. I noticed it starting to vibrate through the steering wheel around 2,000-3,000 miles. The service manager said to bring it in and they would balance the wheels. It didn't help. Then we started hearing a scratching noise in the front wheel and it was still vibrating. They took it back in and kept in for 2-3 days. They said the caliper had come loose and would have to order new hub. They tightened the caliper and said it would be save to drive until the new part came in, that made me feel save! They took truck in again and put on the new hub plus they road balanced the tires. This seemed to help for a while, but the vibration is back, not so much in the steering wheel as it is the whole truck. Day before yesterday I took the service manager for a drive, he felt the vibration up through the passenger seat. I took the truck in again and this time they called and said they were going to order a new drive shaft and it would be another week.
I have read most of the messages and have noticed lots of trucks having the same problem. What can an owner do to get this fixed? Has anyone been able to get this fixed at this time? What are the steps to take with Ford Motor Company?
