Vibration between 50 & 70 mph

[Lo Pony]

Thought the fixed it. Must have been a joke. Vibration is back and it's bad. I wonder if their hose clamp they installed to balance the shaft moved. Vibrates at 55-65 worse then before. lol. F*ck this car.

That is a possibility that the hose clamp moved. SpeedFrk on here had his vibration come back too, and they balanced his with washers on the flange bolts, which should be a permanent fix.

This may indicate that soft components of the drivetrain are misaligning over time due to wear. Moreover, many cars on this board were smooth as silk at day 1 and developed the vibration later (mine included), which overall supports this hypothesis.

My personal favorite suspect #1 is the rubber giubo behind the center driveshaft hanger bearing, or the hanger bearing itself (sometimes called a d.s. carrier bearing). Could be that flange runout/balance matching is only half the problem - more issues could be occurring at the front of the rear D.S. assy. also.

My advice is to definitely take it back in and have them look at it. They seem to be competent at least as far as recognizing a problem exists and taking steps to fix it, unlike some other dealerships (yes, I'm pointing at you, Galpin Ford of Los Angeles).

Let us know how you make out!

Well, my car has been @ the dealer for a week now with no definitive diagnosis as to what's causing the vibration. They do feel the vibration I'm talking about, but said nothing turns up on the vibration tool that points to a specific component.

RCSR has called in Ford Engineering and someone is suppose to come out & look at my car (no ETA on when that might be). Dealer SW did mention it may need to have the DS balanced on the car.

Well, last day of the month and the dealer I bought my car from offered me a sweet deal on a 16 EB to trade me out of my car and problem- basically the same as my current car where I would have traded for less than 1000.00 difference. I was going to jump on the deal so I went and drove the car and sure enough, it also had the vibration problem at 55-70 so I had to decline, of course. I have to go down there again tomorrow since my trunk will no longer open with the button or fob so I'll get the vibration problem back on the books so I can file a lemon law case. What a PITA.

Good catch! Hard to believe they just keep pumping these things off the assembly line, and people keep buying them. I guess this is why there hasn't been a fix .

Do you also get "Trunk Ajar" warning on your display? If so, see my thread in the Tech Issues sub-forum.

I honestly think most people just don't notice it. The salesman said that he doesn't doubt me but he hasn't had any other customers complain. I have to admit that my sister, for example, would not notice it unless I specifically pointed it out. Oh, and the car last night had 45# of air in all 4 tires which made it impossible to differentiate where any vibration was coming from until I set them correctly. The Ford dealers I've dealt with just lack any real concern for quality...

No, no light or warning, it just won't pop open. I think the solenoid is bad. There is no way to use the emergency key that I can find. I had to pull down the rear seat to get my stuff out of the trunk.

Same here. I wrote a thread on using a dog leash run between the rear seats until I went in for service bc I use my trunk a few times per day.

The service advisor said it is usually the electric latch in the lid that gets replaced. But it my case it was kinks in the harness wires from an over tightened cable tie.

 

[speedfrk]

Stopped at the dealer AGAIN, and they wrote up the service ticket and said they will call me when the Ford rep will be at the shop next time so he can evaluate it. He's probably the guy who can make a decision about if they think it is fixable- permanently. I'm honestly scared that it could turn into a every 10k mile thing- get the oil changed and the DS re-balanced, lol.
The trunk started opening again by magic after a full day of not working so of course the problem couldn't be duplicated.

all was going well for my vehicle too, as my 2016 EB was correctively fixed as of March 3, 2016...

until now...

The %&@$#! Center Carrier Bearing is %&@$#! click-clacking-clinking like a %&@$#! MO-FO!!!!

Yep, you read that right. The Center Carrier Bearing is clunking and clacking so loud that it sounds like my trans tunnel is being pummeled by a jack hammer. Over the last few days, each morning when I initially start the vehicle and drive from 0-35mph, the bearing sounds similar to when a drive shaft U-joint end cap is blown off, loud clanking sound that increases with vehicle speed.

I recorded it, and the reason I did was because once the vehicle temp gets to normal operating temp (OR carrier bearing gets heated from exhaust and vehicle speed), the noise diminishes and eventually is gone. So I HAD to record it to prove to my Ford Service Center that the car has another issue with the %&@$#! driveshaft assembly!!

When the car sits for at least a few hours (such as when leaving work), the same noise erupts upon driving away and lasts for a good 15-20 minutes (until car or part is warmed again).

its 109% coming from the center bearing - f you grab either driveshaft (on either side of the carrier bearing) and press it upward (or jiggle it), it makes a solid "clank" noise at the bearing - the same noise heard in the cabin.

The thin walled aluminum "cage" that surrounds the carrier bearing which is secured to the top of the trans tunnel is NOT loose at all. I can see a lot of play in the bearing when pressing or rotating the driveshaft(s).

Why is that bearing cage made of aluminum, so thin and fragile looking?? I mean that is the only piece supporting the center bearing AND the two piece driveshaft! Even the center bearing is very inferior looking especially when two driveshafts are secured to it.

Ugh.

What a Royal Pain In the %&@$#! Ass this new car purchase experience has been. I have NEVER had such Quality Control issues or inferior parts issues with ANY new vehicle I have EVER purchased.

Now I have a scheduled Service Appontment for June 6 (already went to see my FSC Service Manager today who was cool and said he can't even believe it's the driveshaft again!!).

Stay tuned....

If you ask me - the entire 2-piece drivehsaft is a POS design. Ford needs to drop their current driveshaft Supplier, get better parts AND get their Engineering Team to redesign the center bearing assembly, period.

Speedfrk, let me make sure I have this straight - I was wondering about your history with all this.

Should go something like this:

You bought a 2015 EcoBoost = vibration.

Took several visits to dealership, they fixed it with field balancing using washers on the flange bolts.

Vibration returns

They won't trade for a used 2016 GT, but they would trade for a 16 EcoBoost that had the same problem when you drove it.

Now your trunk intermittently opens.

You want to lemon the current car.

The End....

I ask because for some reason I thought there was another car involved somewhere, like you lemoned one already or something?

Just curious.

Thanks for sharing. One Day at a Time, Keep coming back (AA-type lingo).

I agree with you! Not only that, but even if the car is smooth when driven off the lot it can develop the vibration later, so that's another complication. I'm so attuned to this problem from dealing with it on previous cars that I would have noticed it instantly with my new car, and it definitely was smooth as silk when I took delivery of it.

You think the tire pressure would have allowed you to trace the vibration? I've noticed some variation in how bad mine is from day to day, now you've got me thinking that I might be able to change it with the tire pressure. How does that work?

No, I never lemon lawed a car... Ford kept working on this one until they got it smooth. Took 2 months, 8 visits, rental cars, FSE had to come out twice, 2 driveshafts and a pinion flange.
The dealer didn't want to trade on a used 15 GT but on the last day of the month they needed another sale to get over a magic number for Ford bonuses so they were willing to do almost anything to sell me the 16 EB. I would have tried on a base 16 GT but they only had loaded up cars that stickered at over 40K- out of my price range.

Actually, this might be good news! I'm looking at this from a larger perspective. We have been talking about the DS hanger "carrier" bearing for a while as being a culprit. This looks like a definitive case where it IS a problem!

Now, CobraJet - aside from the noise, how does this shot bearing affect the vibration in your opinion? Any worsening since you started having this problem?

Someone mentioned in this thread a while back that they heard through their dealer that supposedly there is a new part number for the driveshaft assembly, which means there could be a design change. Time will tell.
