Who DOESN'T have the vibration? Reassure a prospective buyer.

[shahram72]

I'm willing to bet $500 I could find the issue in about 25% of the people here who report no problems. Loud exhaust? You'll never hear it unless it's really horrible. Not knocking anybody, the issue varies greatly from car to car. I wish it were easy as trading for a Camaro, which I don't even want, but I already spent my trade in and initial depreciation. Can't trade now. I worked so hard for years in unemployment and underemployment. Never thought I would have a car like this again and this. Really killed my dream. Ford should be ashamed of themselves and replace my car. I can't get another V6 they no longer make the GT look package and next year no V6 at all. You think I trust Ford with a 2.3L that makes over 300hp? Hell no! Truck buyers and pony car buyers are repeat customers. They will feel this in the future, but not like I will.

I can't believe the driveline vibration is still being discussed.

Ford narrowed the issue down to driveshaft runout, which was a result of QC at the driveshaft supplier. Hence the reason that they released an SSM with the fix information.

All the dealer needs to do is use the driveshaft balancing procedure that is included with the Mastertech MTS4000 vibration analyzer.

Step 1:

Ask the dealer if they have an MTS 4000. If they don't, leave and find another dealer.

Step 2:

If the dealer has the proper equipment, have the dealer perform the driveshaft balancing procedure with the MTS 4000. If they can't figure out the procedure using the Workshop Manual and the MTS operation manual, ask them to request manufacturer assistance (Field rep). I've never seen an S550 driveshaft vibration that couldn't be repaired using the published procedure; if the dealer can't do it, that's only due to their own incompetence.

Wait. You are offering to travel around the country to test the car of each poster who reports no problem and get a notorized statement from 25% of them saying they now realize they have the problem just to win $500?

I'm interested in how many you have seen / fixed .

Serious question , not trying to be a smartass Just very interested in the issue as I am one of the afflicted .

 

[team_car]

Mind sharing what the dealer did to fix it?

I can't believe non of the aftermarket companies have a solution for this either. I would pay a good amount for a fix, because I can see the vibration causing big problems down to road, in the form of diff/tranny rebuilds.

Abbreivated content of ticket:

Concern - vibration at ~5-70MPH

Cause - rear axle assembly does not operate properly, has extreme vibration issue.

Correction - road force balance, driveshaft swap, balance driveshaft, R & R rear half shafts, road test.

Replace rear axle assembly
Vibration diagnosis Vetronix or EVA
Driveshaft - check runout, reindex, balance

I'm sure the fix (properly done) will address the issue on most cars. I know at one point they sent one of the 3 shafts tried on my car to an independent DS shop & they said it was so far out of balance that they would not work on it, so some are clearly WAY worst than others.

The real issue for most tho is finding a competent dealer to do the work. 2 dealers and multiple FSE's fiddled with mine and could never get it right. Post buyback, Ford sent it to a 3rd dealer on the other side of FL and (apparently) they finally fixed it.

It's appalling that there is that much ignorance @ the dealers and totally inexcusable that the FSE's are not schooled in the proper repair procedure :headbonk:

My dealer followed the SSM word for word including using a vibration analyzer and coming to the conclusion it needed a new driveshaft. For about a month it was fine, but eventually it came back albeit in a different way.

I know I'm not the first person to have the vibes return.

 

[shahram72]

I understand what you are saying. But then tell my why my car which was TOTALLY FIXED.. Had the vibes return a few days later...

The problem I found here in south florida is that there is a lot of dealer incompetence. I can't find one dealer to follow the workshop manuals procedures.

That is far fr M a Florida only issue.

Bingo.

Yes, I'd like SOMEONE to explain the SAME.

FordTechOne, are you an actual Service Writer, Mechanic, or are you the Body Shop guy who just likes to bust balls on this site? Because all of your responses are that the customer is wrong and Ford is right... Or you're doubting the severity of the problem and it really isn't a problem, but again just folks who are complaining about noting.

Funny thing is, it's been said that even in the INTERNAL Ford postings, even the most experienced Ford Mechanics IN THE FIELD are also questioning the issue - EVEN AFTER the SSM has been performed to the T, using all of the correct equipment. EVEN AFTER an FSE has also been out to work on the car, EVEN AFTER the car has been previously "fixed".

So, you seem to be "in the know", what's the deal, can you answer the above question? WHY after the SSM has been performed AND it's been confirmed by the Shop and by the FSE that the fix has reduced or eliminated the vibe, but the vibe has returned after more miles have been accrued?

No vibration here...

I would say, IMHO, it is because of the soft durometer bushing sued for the IRS to attempt to keep away NVH. I squared my IRS Cradle and verified I had no vibration after that then installed the Steed IRS Cradle supports and it never came back until I removed the cradle supports and drove for a bit. Now it vibrates just like it always did before my work.

Think of it like the Tesla Vibration Frequency experiment. Once you hit just that right frequency the effect keeps growing but if you can hold it just enough to stop the resonance then the vibration cannot be felt.

My brother has a 2015 GT PP with no issues. I purchased a 2016 Ecoboost PP the day after Christmas. It has a sever drive line vibration between 50-70. It is terrible to drive at those speeds. It is getting dropped off tomorrow at the dealership. I will share the results.

 

[lawprofs]

No vibration.
