Vibration between 50 & 70 mph

[PonyGrrrl]

You are welcome sir, I'm glad the SSM was helpful to you! :cheers:

Nice work on isolating the vibration in your car to the driveshaft and clocking it to reduce the vibration, that's very good information and may certainly help people who are experiencing a driveline related vibration.

The issue I see here is that others have had their dealer's replace and/or clock their drivesahfts, and they claim the vibration is still present. That means one of two things - we aren't all talking about the same vibration, or the vibration they are feeling is a normal characteristic of the vehicle that they have convinced themselves is an issue.

The other issue seems to be that dealer's aren't doing their due diligence in diagnosing these vehicles. If they replace parts based on the customer's complaint and not based on a verified concern with readings, that is doing everyone a disservice. It seems that a lot of dealers also don't have the vibration analyzer, which makes it impossible to isolate the source of the issue.

For people that have a vibration concern and bring their car to the dealer, I would strongly suggest finding a new dealer if the one you're bringing it to doesn't have a vibration analyzer. As we've seen in this thread, the chance of a dealer correctly repairing the vehicle on the first attempt without any diagnostic readings is not very good.

Winner, winner, chicken dinner! That is a very big problem with dealership service departments in my area.

Looking at this problem in it's simplest terms, customers with new cars, costing a lot of $, are experiencing problems with their cars that they can see and feel. They have contacted their dealers and put their trust into the dealership network to eliminate the problem that they know is there.
The vast majority of these customers have limited automotive mechanical knowledge, so they are reliant on the expertise of the dealers to properly identify the problem and preform a timely fix.

If that fix doesn't happen quickly and the process includes replacing parts that doesn't fix anything, it's only natural the customer will come to the conclusion that either the dealer network doesn't know what they are doing or they aren't interested in helping the customer solve the problem--either which is bad news for someone that has just spent 10's of thousands of dollars on a new car.

If anybody should know exactly what is going on here, it is you people at Ford; you see the data coming in and should know how extensive this problem has been reported.

My suggestion to you and Ford--if it hasn't happened already--is to get the problem identified and set about the work of getting your dealer network clued in on diagnosing and resolving the issue quickly. Keeping customers with affected cars waiting weeks in the hope of a resolution only creates the the frustration you've already seen to in this thread. Picking a fight with people already angry about their new car isn't going to make this situation any better.

That's why a TSB is usually put out when a problem becomes complicated for the dealerships. A TSB basically walks the dealership through a logical trouble-shooting and repair process. Without some direction on a complicated issue, the repair attempts can be all over the place depending on the knowledge and skill of each individual dealership.

Dropped my car off at the dealer this morning since they needed to verify that the vibration has returned. She said something about waiting for the Ford FSE to come out. I doubt they will do anything on it without his input since he was the guy who did the balancing on it last time. Should hear something tomorrow. At least they gave me a decent loaner- 16 F150 crew cab. It's nice but like driving a tank after having the Mustang!

No average person can differentiate between a tire induced vibration and a driveline induced vibration. Failing to see your point.



No cell phone app is even in the same realm as a vibration analyzer tool, which costs thousands of dollars. You obviously don't understand the complexity of the diagnostics required to accurately identify a vibration in a vehicle.



Trying to help, but apparently people such as yourself would rather just complain than present any facts to support your concern.



Which is exactly why it's questionable that so many people are on here complaining. It's a common issue that occurs on the internet these days; one person reports a concern and suddenly a thousand other people mysteriously have the same concern just by reading the post :doh:

On the other hand, I agree that if in fact a vehicle has an issue, the dealer should be able to resolve it without the customer having to resort to the internet. The problem is that apparently some dealers don't have the equipment like a vibration analyzer or a Road Force Balancer, which makes it impossible for them to perform an accurate diagnosis.



No dealer will take NVH readings if no concern can be verified. On the other hand, if the dealer verifies the concern and records the vibration analyzer readings, there is no reason they shouldn't be able to pinpoint the issue to a specific system. If the dealer can't do that, especially with the help of a Hotline, then something is clearly wrong.

I fully understand all the complexities involved. Do a search on the "Internets" for Lo Pony and drivetrain vibration and you will see what I mean, all the way back to 2002.

Your response to my post indicates that you do not understand sarcasm, even when it is directed at you. However, thanks for being helpful with your subsequent replies. You will actually be useful here, as there is a great need for technical expertise. So please, why don't you concentrate on doing that for us and helping people solve their problems instead of contributing to them. Otherwise buzz off.

Mine's been sitting for 2 weeks now waiting on the FSE to come out :shrug:

They gave me a Focus to drive, would have LOVED to get an F150 !!

Part of me is hoping it gets stolen so I can move on ...................

 

[Furious D]

The dealership is planning on running a vibration test on mine.


...That will be after the 7-10 days it will take to get the parts for a new oil pressure sending unit :doh:

Here's hoping the first 10 days I've owned this car won't be indicative of the remainder of this relationship!

LOL...
I really like my car but I can't deal with the back and forth while they try to diagnose/fix it. It's 20 miles each way and it eats up a minimum of 2 hours every time. Kills my days and work productivity. I think since this truck is a loaner from the dealer and not a rental car, they will just let me keep it until something is resolved.

they should loan everyone the most expensive mustangs on the lot until they get yours fixed. would be great motivation on their end to hurry the fuck up.

Ford tech raises some valid points, but most of us are car people, have worked on cars, owned and driven many cars for many years and know how they should feel. There are two sides to this argument... The customer who reads on the internet and then thinks their car has the problem and is obviously mentally insane. And the dealer who thinks that no car has any problem and everything is normal and that's insane too. But I got to call this comment....

That's some BS right there. They feel and sound TOTALLY different. There are many different vibrations in a car like this. You have tire induced, which is one, road surface which is another, and the rare (not for Mustangs apparently) driveline vibration which is different still, but can be hidden by road surface noise. Actually, rough enough road can hide almost anything. The first time I drove a Mustang was a test drive. A V6 with 18" wheels, just like I had. The sales guy was surprised I was driving so smooth and calmly. I owned an Acura at the time. I knew the Mustang was quick and handled well, I wanted to hear how quiet and smooth it was. I was AMAZED! It was just as smooth and quiet as my Acura, driveline wise. More tire noise of course, but not much. So I bought mine site unseen and it was horrible. A driveshaft later it's better, but not good enough. I have owned and ridden and driven other Fords with IRS and they were all wonderful. This is crap. Most of the asserstions you poo-pooed were valid. Piss poor parts or installation. What is it then? The engineers said, ah Mustang owners are so stupid they'll never notice? They even mentioned it in the documentary. I know what it is. Companies are run by short sighted bean counters now, not real managers. Something is not working in the parts and/or assembly and the cost to stop production and retool whatever would cost X amount of dollars. Much cheaper to let the dealer fix them in the field, even though they can't. Screw the customer, the bean counters said. This is how American business work nowadays and anyone who has been at a large company for any amount of time knows this is true. It's sure how it works at my company and it's the same thing, Union and all. The employees all know they're building them broken, many have posted they know they are broken on social media, management does not care so why should they? It's just a job, they can't do anything about it.

If it makes y'all feel any better I have a new Honda that also has a vibration issue from the CVT combo in this chassis. I don't have the will to be that concerned or I would shoot myself. At least Honda issued a TSB and did quite a bit of work to make it better. Honda even delayed production of the 2016 model until they got the TSB out for the 2015. Ford's lack of TSB at this point means they either don't know how to build this car or they don't care. I think the latter... But then, it's all in my imagination....

Here's a new one....I'm getting this exact 55+ vibration after installing the DSS. Keep in mind that the stock driveshaft, and the DSS never had a problem until it went down for a new set of rear end gears. I'm taking off the driveshaft and getting it re balanced here locally. Everyone can relate with the rear view mirror vibration at these speeds.

its a waste of space best thing is to ignore it and not feed it, hope that it eventually goes away.
