2004 Ford F-150... truck starts to shake horribly when accelerating. The problem is random (once every 2-3 days?), but only stop S after the car comes to a complete stop. Most of the time the problem arise when accelerating on the interstate. It feels like driving over a washboard, which is very unnerving when traveling at 60 mph. I have repeatedly had to pull of the interstate, stop completely (maybe twice), before the issue is resolved. The issue has not yet been diagnosed by the dealer. Other people say it has to do with the rear differential, but not sure yet, since it has not been repaired. No injuries yet, but the problem seems very unsafe and widespread. Problem started in October 2007, and has progressively gotten worse.

Since purchase the F150 has had terrible shaking in the front at 55-60 mph. Repeated attempts to fix have been negative. Dealers, repair shops have failed. Replaced all four tires, repeated balancing have not helped.

I purchased my Ford F-150 as a demo in 2004. The truck has been back to the dealership at least 5 times for a vibration over 60 miles/hr. The truck now has just over 46,000 miles and I just put the 4th set of tires on the truck. The dealership states there is nothing they can do. I have read many online forums about the same complaints with this Ford truck. Two weeks ago I spent over $1000 dollars on tires and alignment, the vibration is still present. My next step is to file for the lemon law.

At least once a week our truck will go in to a violent shaking episode. The majority of the time it rides beautifully. There doesn't seem to be a pattern other than it begins after the truck has been parked and started to be driven again. It feels as if the wheels are falling off literally. It seems to be suspension related but sets off no engine light or warnings. Usually if my wife or I stop the truck, place it in park, shut the truck off, the problem will stop. It is such a violent shaking that the vehicle can not be driven and must be pulled off the road. Here in amish country not all roads have emergency lanes and this has put us in some dangerous predicament. Had the truck in to one dealer who could not replicate the problem. I have an appointment next week at another dealer for the same issue. I normally carry no load and no towing has been done with this truck to date.

Every time you reach the speed between 65- 70 mph the vehicle / steering wheel shakes as if the tires are not balanced. I had them balanced 3 times already and it still does the same. Rear end of vehicle throws to L/R when going over bumps. I've test driven other makes and there isn't a problem going over the same bumps.

Intermitent shaking of vehicle while driving at any speed and only stops shaking when vehicle is brought to a complete stop. No warning that truck will start shaking. Brought truck to dealer three times and dealer could not replicate shaking, says nothing is wrong, refuses to take any action. Service bulletin advises addition of rear suspension damper but could not be installed due to interference with dealer installed trailer hitch. Dealer is refusing to replace existing trailer hitch with another trailer hitch that would allow installation of damper.

Ford F150 truck - the truck intermittenly exhibits severe vibration that can be felt in the steering wheel as well as in the cab. The whole truck shackes when this occurs. The vibration occurs primarily at speeds of 40-60 mph; but, has occurred at speeds in the 75 mph range too. There is a low level vibration that is present most of the time while driving. This low level vibration turns into the severe vibration periodically. The problem occurs on smooth pavement. It is very scarey when this problem occurs. The drive shaft and engine mounts have been replaced and the dealer tried 4 new tires on the truck too. The problem still exists.....alas it is intermittent and the dealer has not seen it. One interesting fact. When the dealer puts the truck on the lift to check it, the problem goes away for a week or two; but, then returns.

Had to put 4 sets of brakes on vehicle since purchasing the car. The rotors were getting grooved so badly that vehicle pulls off the road. The consumer talked to Ford, and they ignored him. He traveled and saw this problem with several other Ford cars. Ford told him it was cosmetic. While on the first trip with this vehicle, the rear end had gone out, the clutch pack was removed and replaced, the fog lamps were holding moisture and were replaced, the brakes would pulsate and pull from one side, the shifting was harsh when changing from first to second gear, a loud clunk would be present at times when starting from stop then decelerating and the vehicle would crank but would not start at times.

The entire truck will vibrate at any speed with cause unknown. The area dealership examined the truck but was unable to determine a cause. While at the dealership the owner was made aware of two similar F150 pickups with the same intermittent vibration.

10/19/04 puchased a new Ford F150 supercrew. I discussed a vibration I felt while test driving the vehicle with the sales person. He said it was flat spots on the tires, and they would take care of it after the purchase. Scheduled to take it in the shop 3 days later for repair. I was told that the vibration is a know problem on 2004 some 2004 F150 trucks. I have everything documented in detail I can send. This space limits me to 2000 characters.

Steering wheel vibration at 65 to 70 mph. Followed tsb 4-25-8 which did not resolve the problem. Ford dealers have been unable to fix the vibration issue. Experiencing excessive tire wear, Ford has extended tire warranty to 36,000 miles.

Excessive vibration at most speeds, most noticable between 40-50. The truck is now starting an unusual shake/rebounce on very smooth roads as well. 4 attempts to fix and nothing has been done to correct this issue. Bought at 15 miles, no problems, started around 1500 mi, now at 6200 and it's getting worse!!
