I have a Screw 4x4 w/ 3.73 ltd slip rear. I love my truck it has been great best truck I every bought but... I’m having the same problems many of us have experienced with the steering wheel vibration at highway speeds and the rear end slipping feeling from a standstill. I brought the truck in this week and the service writer had the service manager take a test drive with me so I could show him what I was talking about. He felt the exact same things I did, acknowledged the vibration and the slipping rear end feeling.

Long story short, after a few days of them trying different sets of wheels and tires on my truck they called Ford and have arranged for a Ford Engineer to come take a look at my truck, just for the steering wheel vibration problem not the rear end.

Service rep said there is no fix for the rear end, and a new clutch pack does not fix the problem.... He also stated that from what he heard, it's the drive shaft not the clutch pack. “The drive shaft is currently being redesigned and that was the cause of the problem”. Could this be true?? Anyone heard this before?

I also noticed on my copy of the receipt when I picked up the truck that it said: “Customer reports slipping in rear axle upon acceleration from stop. Road tested, did not find any rear axle slippage” I could not believe they wrote that when the service manager agreed with me that yes there is a problem with the rear end. I'm going to try to get the Ford Engineer to take a look at the axel as well. Just goiong to keep documenting everything just in case I need to lemon law this truck. I'll let you know happenens this week.

 

There's no way the drive shaft could be slipping. Only a very small amount of slack if a u-joint is bad. Does it feel like its slipping every single time you take off? Does it shudder when turning a corner?

 

Yes every single time from a stop, it shutters. I thought the same thing no way it's the drive shaft... Just trying to jerk me around.

 

rover.. keep your ear to the ground about that driveshaft redesigning you heard about....just incase it is true but doesn't apply to your problem..
It could apply to my problem and others who have a speed related vib.

My dealer's shop manager basically rolled his eyes when I said there was a vib. I take it in Monday to be checked out... roll them eyes again and there will be a $40000 kick in the nutz..

Thanks

 

The people with the clutch pack problems have said that it usually does it when turning a corner. Somebody said that they drove in the tightest circle they could for 3-4 revolutions and it freed up their clutch pack. They said their problem was when they turned right, so they did right turn circles. You might try each direction and see if it helps. That way you might know if it is the clutch packs, lot of empty parking lots today also.

 

It seem's to me that Ford is in denial that there is problem's with there new truck,also seem's that they have passed this on to the dealer's as well. Everytime I ask the service manager If they have heard from Ford his answer is no. He also acts as if I have the plague everytime I call. Well Im going to the dealer tomorrow and try to get some answer's.Also how can a driveshaft cause the rearend to slip ,that's BS. Mine slipped bad coming out of my driveway yesturday,while I was hooked to my trailer,this was not caused by my driveshaft,unless it has a clucth in it im not aware of . I will post what happen's at the dealer tomorrow.

 

I was at the dealer last week just to look at some running bars. I asked a service "advisor" if they have had very many problems with the F-150. Of course, as usual, have not ever heard of any vibration problems, only 2 clutch packs and thats it he said. He did agree with the way I described how the front end feels loose when you hit a small hole at low speed, that surprised me. He said they changed a lot of clutch packs in the Expedition. But yeah service advisors usually will deny everything from my experience. I think its part of their 3 day training program.

 

I do think Ford is in denial about these problems as well.

I think we need to organize a specific day that everyone who has these problems (Vib and/or clutch pack prob) calls Ford, to bombard them with calls from all over the country.

Maybe this will get them to listen to us if we all voice our problems at once.

 

Sounds good, a consumer "Union". I'm curious as to what the % is with people having problems to total # of trucks sold so far. Just think about all of the people who don't have access to these websites or forums and are having problems. They probably think they are the only one.

 

Hi-

I have had the same problems with the vibration & shutter . My shuuter was from day one from starting straight from a stop-light. Now , for the past few weeks, it has ALSO been acting up with the 'Famous' shutter when turning to the left and right (I don''t think that two 'shutters' are the same!). This, in combination with the excess wind noise from both rear door areas , and the nice 'bumpity-bump' & skating ride when going over small bumps in the road has made for an enjoyable owning experience for the last 6 months. I approached my service advisor last week to continue to tell him of the issues, and he is telling me others in our local area have had similar issues. - Ford is going to lose some customers unless they fix these issues. It's still astounds me that they can put a product out like this , and brag about sales; then--- hide from the issues! What do you guys think?

It astounds me also. I just can't believe all the great reviews and raves it got for the last 2 years from numerous different sources who tested the vehicle. Ford tested it for 150k miles, it must have been the same single vehicle. I never read any bad reviews about the ride, any vibrations or anything. Goes to show what alot of hype and good press can do for a product. Not to mention "Motor Trend Truck of the Year".

 

I am still having trouble with the shuddering issue. I posted before that the dealer has tried two seperate times to fix the proublem. First they put friction modifer in the rear end, and greased the slip yoke. Then the second time they replaced the drive shaft. I was told to drive it for a while and see what happens. Its been 5000 miles and the problem seems to be worse. I will be going back soon. Someone in an earlier post gave a part number for this fix. I believe it was a replacement clutch pack?

Good luck and keep us informed. I know it will be at least two weeks before I get another day off to persue it.

 

Yep it sure make sou wonder what the hell good all the so called testing on their test tracks real road conditions etc etc

Ford is banking on this new model NOT being plagued like previous first year runs


Sure screwed up didn't they

 

I had the same slipping problem when turning right or left. Also, when starting out straight, sometimes. I waited until I had about 8500 miles and then took it back to Central Ford Truck in Lansing, MI. I gave them a copy of one of the threads about this problem and no questions asked they ordered the clutch packs and replaced. It fixed the problem completely. I am sure that is the fix for everyones shuddering problems.

 

I'd like to say it's impossible for the slippage to occur in the driveline, but I always try to speak the truth, it could happen if you strip the spline but it would fail, not be a recurring symptom.

dgdee, congrats that your service writer got 3 days training, around here it's OJT
