ISSUE:
Some 2004-2005 F-150 vehicles may exhibit shudder/vibration on moderate to hard acceleration.

FORD: 2004-2005 F-150
ISSUE:
Some F-150 vehicles may exhibit a vibration, felt in the floorpan and/or steering wheel when driven at highway speeds.
ACTION:
Refer to the Diagnostic Overview (Figure 1). Based on the customer's description of the concern, find the appropriate Operating Condition, Probable Cause and Repair Action.
NOTE: IT IS CRITICAL TO IDENTIFY SPECIFIC VEHICLE SPEEDS AND OPERATING CONDITIONS WHEN THE VIBRATION OR NIBBLE IS OCCURRING, TO PROPERLY DIAGNOSE AND REPAIR THE ISSUE. TIRE AND DRIVELINE VIBRATION CAN FEEL SIMILAR. USE OF AN ELECTRONIC VIBRATION ANALYZER (EVA) OR VETRONIX VIBRATION ANALYZER IS RECOMMENDED TO CORRECTLY IDENTIFY VIBRATION SOURCES (ORDERS) AND FREQUENCY (HZ).

On 4x4 vehicles, the sensation may appear to be originating from the front axle or the steering gear.

FORD: 1998-2004 F-150
ISSUE:
Some 1998-2004 F-150 4X4 vehicles with a one piece drive shaft may exhibit a clunking or grunting noise and/or a shudder sensation from the driveline. The condition will typically occur during light to moderate acceleration from a stop and/or braking. This may be caused by the slip yoke not sliding smoothly on the transfer case output shaft splines.
ACTION:
To service, lubricate the slip yoke with Teflon Grease (D2AZ-19590-A). Refer to the following Service Procedure.

FORD: 2004 F-150
ISSUE:
Some F-150 vehicles built prior to 8/20/2003, may exhibit a Steering Wheel Shimmy/Nibble at 100 km/h (60 MPH) and greater speeds. The condition is felt in the steering wheel as a side-to-side, or rotational, oscillation. When measured (sensor on steering wheel) with an Electronic Vibration Analyzer (EVA), the measured frequency is between 12-16 Hz.

hopefully this will help you guys at your dealerships

here is the short and sweet

vib on corners = clutches

vib on accel (straight, from a stop) = lube slip yoke with teflon if that dosen't fix it, check d\shaft angles, shim as necessary.

vib noise\whine at 40-60mph (steering wheel vibrates up and down not side to side)= gearset, possibly d\shaft, and at last transmission


vib in wheel (side to side) = tires or p\s rack

 

These are just their possible fixes....most of us have had all of the crud done to our pickups to no avail........the slipclunk is the tranny, but they play with the driveshaft, stick shims in (and if they're lazy....put the leaf springs back on crooked) and grease it up

good info....but most of us have read the tsbs over and over.......and yet, after all that... i settle with ford to take my 05 back and refund my money.....now i have an 06.....that even though i thoroughly tested it....started lightly slipclunking after i bought it......so who knows where to go from here.

i hope your info does help someone though. its getting the dealers to try the fixes thats sometimes a pain (they seem to just hate it when you walk in there with a tsb in hand)

 

Dealer service departments just hate when you bring in the TSB's. Now they have to work even harder to convince you that you truck has not issues.

 

Dealer service employees should be banned form using the phrase, "That's normal."


How many times have we all heard that one?

My favorite is "Operates as Engineered"

 

It's within tolerances. I love that one.

ISSUE:
Some vehicles may exhibit a tire/wheel vibration caused by excessive runout.

Hi all,

Could anyone give me more info on what "excessive runout" is as it applies to this TSB....

I believe I have a tire problem, 06 F-150 Scab. At 58 to 60 MPH a have a vibration, enough to shack the truck. Below that it's just barely noticable, same for above that speed. It's worse on cold mornings until the tires heat up (approx 10 miles of driving).

I had the tires balanced @ 500 miles. The truck now has 850. The service dept told me to come back @ 1000 if it has not gotten any better. I was thinking I may wait until I have 1500 and then press the point about this TSB.

I prefer to go in the dealer "armed" with as much info as possible. I have already heard the "they all do that" line from the service writer. My reply was, "do you have the engineering documents form Ford showing they built in a vibration?" She gave me her best "dumb blonde" look.

Other than that, I'm not having any other problems...

Thanks in advance!

 

try the thread on the ebrake (its right near the top under bad vib in 06)

i don't know what ex runout is either, but maybe its early wear?

 

Countryboy69, Thanks for taking the time to consolidate all of this.

 

what is excessive runout?

Thanks Phrekkle!

Here's the info from the website:

Question 98: What causes a vibration when I'm driving at highway speeds?

Answer: The most likely cause is an out-of-balance wheel and tire. But vibrations can also be caused by a tire or wheel that's out of round (excessive runout), "heel-and-toe" wear on a tire, driveshaft imbalance, or even harmonic vibrations in the engine and drivetrain.

Wheel balance: For a wheel to roll smoothly, it must be properly balanced. Balancing the wheel and tire involves spinning at high speed to determine where the "heavy" spots are. Small lead weights are then positioned opposite the heavy spot to counteract the forces generated when the wheel spins. If your wheels have never been balanced, if you've lost a wheel weight, or if you've put a lot of miles on your tires since they were last balanced, wheel imbalance may be causing your vibration problem. The way to find out is to have the wheels rebalanced. If the vibration goes away, you've cured the problem. If the vibration remains, then it's something else. Wheel balance problems can usually be felt in the steering wheel, and grow in intensity the faster you drive. Below 45 mph, you usually don't feel a thing. But by 55 or 60 mph, you feel a steady shake. Most wheels today are balanced using an off-car electronic spin balancers. These machines are extremely accurate and usually do an excellent job of balancing wheels and tires. But because the wheels are balanced off the vehicle, the machine does not take into account any imbalance in the brake rotors or drums. Consequently, you may still have a balance problem even though the wheels have been properly balanced. The cure here is to have the wheels balanced using an "on-car" wheel balancer. Though on-car balancers are hard to find today, and are difficult to use on front-wheel drive and four-wheel drive vehicles, an on-car balancer will compensate for rotor or drum imbalance.

Wheel runout: If wheel balance isn't the problem, the next thing to check would be wheel and tire runout. This usually requires positioning a dial indicator against the center of the tire tread and noting how much runout occurs as the tire is rotated by hand. More than about .050 inch of runout can cause vibration problems. If you don't have a dial indicator, hold a pencil or stick on a block of wood near the center of the tread and observe how much the tread moves in and out as the tire is rotated. If runout is more than the thickness of a nickel, it may be your problem. Runout can be corrected several ways. One is to remove the wheel and remount it on the hub in a different index position (lined up so the lugs go through different holes than before). This may help to reduce runout caused by an off-center hub or a wheel that wasn't manufactured with perfectly centered holes. Another way to correct runout is to dismount the tire from the wheel. A dial indicator can then be used to find the high and low spots on both the tire and wheel. The tire is then remounted on the wheel so the tire high spot lines up with the wheel low spot. This may reduce overall runout to the point where vibration is no longer a problem. If that doesn't work, a "tire truing" machine (if you can find a service facility that has one) can be used to shave rubber off the tire and make it round again. This will reduce the life of the tread somewhat but it's cheaper than replacing the tire and/or wheel, which is the last resort to solving a runout problem.
