#1130 of 2180 2005 F-150 VIBRATION AND DRIVE-TRAIN SLIP-SLAP-CRUNCH
May 12, 2005 (10:18 am)
To all those having problems with 2004 or 2005 F-150 vibrations and drive-train problems. Here what I am experiencing and I have hired an attorney to process a "lemon law" case in Ohio in forcing Ford to take this POS Ford back. I have had the rear axle assembly replaced with less than 1000 miles on the vehicle and three tires replaced "Goodrich Rugged Trail". I still am having the following problems. Simply stated. This vehicle appears to have serious engineering problems. I think they may have lightened the cab up so much that every vibration the vehicle generates from either, engine, driveshaft, differential, etc is resonating up throught the cab. Thus, no fix. Truly a lemon. See your attorney looks like the only relief fromt his lousy vehicle. It makes me sick I traded in a real nice performing 2002 F150 for this thing. That was a good truck.
1.. Vehicle continues to generate excessive drive train delay-slip-slap-crunch (for lack of an encompassing term) at various times while starting and driving in start and stop traffic. i.e. when accelerating from a dead start, when decelerating in a road dip and accelerating out of a road dip, when decelerating and slowing to make a turn and accelerating out of a turn. The slip and slap is also experienced at times when slowing and the vehicle downshifts. A very bad situation: Is when slowing down or rounding a turn and then accelerating out of it. Where at that certain speed when the torque from acceleration pulls out the drive train slack and the transmission shifts to the next gear simultaneously. There is a slap and thud that will make you think the wheels are falling off this vehicle.
2.Vehicle continues or has returned to generating excessive cab vibration under at least three different driving conditions. I performed three specific tests on smooth road with long inclines. First test was performed in the early morning 6:00 AM when colder and the second in the late afternoon 4:00 PM over the same road when outside temperature was 80 degree’s. Tests one and two were with a #3000 tow load. Third test was without a tow load.
a. When drive train is under torque while climbing a long road incline without a tow load. Such as the long upgrades on I-70 east of Rt 13. When reaching top of grade and decelerating or coasting the vibration diminishes.
b. When drive train is under torque while accelerating with a tow load while climbing a long road incline and also on flatter terrain.
c. When accelerating in general at slower speeds during acceleration and while generating drive train torque. However this vibration is not as aggressive as a and b.
3. Vehicle is still generating hard tire or flat spot thumping response. Thumping is excessive when tires are cool to cold and lesser when tires are warm to hot. This can be experienced when reaching the top of a long road incline during the deceleration or coasting phase as mentioned above which eliminates the drive train interference for tire ride detection. If tires are cold the tires thump harder if the tires are hot it is much lesser but still apparent. Detected during first and second test in item 2 above.

Unfortunately the 2005 F-150 has all the same problems you discuss. I have had three new tires and a rear differential and still have the vibration when vehicle is under torque of any kind. Also have slip-slap-crunch sound coming from the drive train on acceleration and when slowing and then accelerating. This platform is truly junk and definately a lemon. See you attorney about a lemon law case just as soon as you have three service orders attempting to fix this problem.
All the mail on this issue indicates dealers are just trial and error attempting to fix this problem without really knowing the true cause.

How about where is the jack in your F-150?

In my 2005 F-150 super cab it is located under the rear seat on the passenger side.

Update on my previous message: I noticed someone stated that vehicle details would be helpful when you post a particular problem in helping others better relate the issue to their own set of circumstances. Good idea. Here are my details in respect to the vibration problem on the apparently 2004 and 2005 F-150 platform.
Amazing this significant problem carried over from 2004 to 2005. This platform was apparently released premature and is a true engineering failure for Ford. My truck is a 2005 F-150 Lariat, 4X4, 5.4L, Limited Slip, Super Cab, 3.73 differential, column shift automatic. It has both a substantial vibration problem and substantial drive train slack problem. It also sounds like the gears in the differential do not mesh well on acceleration as there is a slip then a crunching type sound. See Message #1130 for a more complete analysis of my problems with vibration and drive train noise. I saw where someone still had vibration problem with 3.55 rear axle. I am wondering if the 3.33 differential that used to be in 4x4 and now only 4X2 is experiencing these problems as well? I know my 2002 F-150 4X4 333 gears was rock solid compared to this 2005 POS.

I am sorry to read about all the problems people are having. I have been gm all my life .Now i have my first ford , its F-150 FX-4 SC. This is the best new tk we have ever owned . Lots better than my last two gm trucks. 13000 miles not one thing wrong towing or otherwise. I would buy one agan in a heart beat. My brother liked it so much he went and got one. He loves his to . Good luck i know there is a lot of problems with some trucks . BUT THERE NOT ALL BAD

Next thing to check would be any type of electrical drain. Even though lights and the stereo will come on, you still may not have enough juice to get the diesel fired up. If a jump gets it going, it was a discharged battery, and you should have them checked anyway.
If you can completely rule out batteries/alternator/starter, then you may have a fuel delivery issue. This could be a dead fuel pump or injectors. (Hopefully, no one siphoned your tank dry in this day of high fuel prices.) You could also have an issue in the glow plug circuitry (short, etc.), although the engine should fire without them, just with great difficulty.

#1137 of 2180 Why 2 Different Driveshafts on F150 Supercrews?
May 14, 2005 (9:13 am)
I have a 2004 Lariat Supercrew 4x2, with which I've had my share of vibration and dealer problems. A new driveshaft and a shim in the carrier bearing seem to have solved about 95% of the trouble. My question is why some otherwise identical trucks have a 1 piece driveshaft, and others, like mine, a 2 piece assembly? My manufacture date is 5/04. The 4x2 Supercrew I looked under, with a 1 piece driveshaft, was manufactured 1/04. The owner of the 1 piece truck said he never had any vibration issues. I've also looked under two 4x4's, both of which had 1 piece units. Does the vibration occur more in one type than the other?

I agree. I bought a new F250 diesel in December after having owned an Expedition for 6 yrs. Nothing on the Expedition was required other than scheduled maintainance. The new diesel is awesome and one heck of a tow vehicle!
I recently went on a trip in a friend's Honda Pilot for 200 miles and back. Lots of road noise, the seat cushions are short with not much leg room and the ride was nothing to brag about. I don't see why people even buy them. Give me my F250 anyday!
#1139 of 2180 towing question & rough engine
May 14, 2005 (11:30 am)
I have two questions. I just bought a used 2002 F-150 extended cab, longbed, 58,000 miles, with the V-8 two days ago. It appears to have been kept very well by the previous owner.
First, the towing question. It has a towing package installed rated at 5,000 lbs. max. I am going to be towing a 1999 Mazda 626, front wheel drive, manual transmission, from California to Iowa in a couple months. My question has to do mainly with which type of trailer I should rent. I know a tow dolly can work, but am wondering if a full-size trailer would be more stable and easier to tow for that long of a trip?
Second, the rough engine question. Like I said, I bought it two days ago. Ran great. Drove the you-know-what out of it and no signs of trouble at all. Later that evening I took it in to have the factory cassette replaced with a new CD player. Didn't drive it yesterday, Today, it starts running rough and idling rough, though not always. I read in the owner's manual that when the battery is disconnected that the computer has to "relearn" idle and fuel settings. It even has a sequnece for helping it do this, and I seriously doubt it has been done properly. Since I'm sure they disconnected the battery when they installed the CD player, and it seemed fine before that, is this most likely my problem? Or, should I be searching for something else? Thanks.
