#1838 of 2180 2004 F150 Vibration (clutch pack) by hipstra

Jan 30, 2006 (12:54 pm)

My 2004 F150 4X4,automatic, 5.4 liter has started the "Vibration Thing" at 21000 miles. When I make a sharp turn from a stop under acceleration the rear end / drive train vibrates severely. Also as I am straighting up from the turn it vibrates again.
 
It appears to me to be the limited slip differential or posi-traction rear end. The posi-traction rear end has clutch plates that are engaged when going in a straight line. On road curves and sharp turns one side of the clutch pack should disengage to allow free wheeling on one side. I think the clutch pack is not operating properly. This was an old problem with the old posi-traction rear ends (1955-65) but the new stuff is not suppose to chatter around corners.
 
I plan to take it to the dealer for repair under warranty. Either an oil additive to help release the clutch pack causing the chatter problem or a new clutch pack. The "Rice Burners" do not have this problem. Could this be a "Secret Recall" item from Ford?

Big Dave and all the rest of the F 150 owners: Went through the whole process with my dealer and Ford. The vibration problem is called harmonics and Ford has serious design problems with the F-150. All else said the truck is an execellent vehicle. Solution...file for Lemon under your state guidelines. Make sure you keep very accurate records regarding repair attempts and outcome of each. Get repair invoices!!!!!!! Good luck to all and keep us all posted

Found this TSB from Ford which answers some questions and indicates that a new clutch pack in the limited slip is in order--not just adding some additive. Look at this link to get the TSB.

#1841 of 2180 1995 f150 manual transmission problems by vmat

Feb 01, 2006 (8:38 am)

I have a 1995 F150 4.9L 2wd with a 5 speed manual. 100k miles. After driving for 10-15 miles, when shifting into 2nd and/or 3rd gear under load a loud screech from the transmission is heard. It does not do it when the vehicle is cold and as soon as you let off the gas or take it out of gear the sound stops. It also does not happen in 1st, 4th or 5th, although it feels like it is hitting a wall when you try to drive in 5th gear. The dealer says they can not find anything wrong with it. Has anyone else had something similar happen?
 
Thanks

Sounds like a transmission bearing failure.

I just took my 2005 F150 (Supercab 4X2, 5.4L)in for a serious problem with a vibrations in the chassis at certain speeds. It seemed that 50-55mph and 60-68mph cruising speeds are where it was mostly observed. Over a period of 1 year it became more constant / serious. It happens more often when you left off the gas at cruising speed for a few seconds then press it to maintain speed (before and just when it shifts back down to overdrive).
 The dealership came back and told the the whole rack and pinion system needs to be replaced. Acoording to wha the Ford Dealer told, the vibration is as you expected in your question I read. It will be interesting to see if this fixes the problem.

I have the exact same problem with my '91 F150 and I was just wondering if you figured out what the problem was yet.

#1847 of 2180 power programmers by jdfrmky

Feb 04, 2006 (10:41 am)

I've a 2004 F 150 37k miles 5.4 motor.I use the truck to cruise mostly.i've a driveability problem the dealer can't correct(check engine light does not pop on)and they do not have a fix from Ford.They corrected it once then the fix went away for a few days.Truck hesitates like a carburated vehicle with improperly set float level.You all think it would be worth it to reprogram with a power reprogrammer just to make it driveable as new?Anything would have to be better than going roundy round with the service department.I like the truck, not the way it runs.
 
This is a GREAT Forum for usable advice.thanks
