Vibration when decelerating from 3k rpms

I have noticed that whenever I decelerate from ~3k rpms in a low gear, the car vibrates a lot.

After a very small amount of research (basically 1 google search), I found that a great deal of people have the same issue and many say it is due to the 2 piece driveshaft.

If this is the case, how did Ford overlook this???

It's not a major issue but I feel that it exposes a significant amount of unrefinement on Ford's part.

Is anyone else kind of bothered by this?

How significant? I have a slight vibrating SOUND on deceleration that I know is my driveshaft. If it's actually vibrating the car, you might be in dire need of an alignment rather than a driveshaft.

It doesn't vibrate the car to where it's visible but I can feel the vibration in the seat and shifter. It can't be an alignment problem because it tracks straight, brakes straight, and doesn't show any signs of pull on a flat road. It seems to be a common problem, it just annoys me how Ford overlooked this.

If it's in warranty, go have them check it out. Might be a bad u joint or the joint in the actual shaft.

Auto or manual? If its a manual its probably the dual mass flywheel. I have it also on deceleration between 3k and 2500. Google dual mass fly wheel mt-82 vibration. Unfortunately its normal on these transmissions.

Yeah, it definitely seems like a really common problem from what I have seen. It just bugs me that Ford released it like that!

A little bit, nothing that's bothersome though.

It definitely freaked me the first couple of weeks I had the car, but as it turned out its normal. I've learned to just ignore it now.

It looks like i will have to ignore it too. I am so happy with everything else about my car that the vibrating is only a small price to pay

I have an auto and just recently I started noticing this. Does not vibrate to the extent where it's visible but you can feel it, although I've been ignoring the vibration since it doesn't do it all the time. Is this "normal" on an auto like on the manual?

Black1, for mine it only shows up if I 1st get north of 3500 rpm then when you lower rpm to 2500 you feel it. It is in all gears and if you keep rpm at that range it will continue. I put in motor mounts which aided shifting alot but make the vibration feel just like mild rumble strips. It's one of those deal with it problems but IF I ever need a clutch I'm gonna replace the flywheel too.

Yeah, sounds like the same thing i have. BTW, does anyone know how long the v6 manual clutch typically lasts for?

Sounds like a pricey fix for something that Ford should have put in to begin with.

how long is a piece of string........? (Zen saying)



The clutch should last as long as any clutch does, it's all in driving style/conditions. My fear is it will last longer than the transmission.

I was just asking because i sit in bumper to bumper rush hour traffic 5 days a week and all the starting and stopping can't be easy on the clutch (which i totally understand/not the car's fault).

Yeah it's a little pricey. But eliminates vibration almost completely, better throttle response, annnnnnd you can go over 120 mph without the driveshaft failing like the stock one haha

Better throttle response is attractive (but really how big is the difference for the price?) and i would never think of taking my car past 120MPH because i don't want to track it and I'm not crazy enough to do it on the street.

In the long run I think it's worth it. I hated the vibration at low rpms in 6th gear. At least with the aftermarket driveshaft you will feel safe about your car. Knowing it won't fail and fall apart from hot rodding around. It's a good idea if you plan on adding power

I agree with you that it's a great supporting mod if you plan on doing a few power mods, but i don't see myself doing anything serious (other than a tune).

Then I wouldnt worry, unless the vibration eventually drives you crazy. It is sad that Ford would use a crappy part like that

If and when you do the clutch just replace the dual mass flywheel while the transmission is out, problem solved. The real issue with the vibration is more centred around the flywheel than the DS. The main reason that ford uses that pos flywheel is because it lessons the "jerk" between shifts which makes for a smoother engagement between gears, but it comes with its notorious declaration vibration trade off. This is what I gathered from others with the same problem.
