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

Plenty of vibrations here. Two driveshafts and a differential change out. The mustang rented loaner car had the vibrations.

No vibration here.

One thing to keep in mind is that for every person who has a problem on an enthusiast forum there are probably something like 10-50 people who don't have the problem. Generally people only complain when they have a problem so online, issues seem to be amplified.

I agree with everything said above. I can also confirm I have had no vibration issues with my S550 going on 2 years now.

2017 Ecoboost Premium, already have 8k miles on it and no vibration.

I seem to be in the minority that has had a vibration successfully fixed (at least a couple thousand miles post-fix).

After I squared my IRS cradle and installed the Steeda support braces my vibration is gone

How did you square your IRS? Is it something that most people can do with basic tools?

What vibration?

actually yes. so look around page 7 of the Maximum Motorsport K-Member install instructions. Now instead of putting the plumb bobs on the rear put them up front on fixed even points, say kmember mount bolts, and square the irs brace off of those points.

I haven't noticed any on either of our cars. After replacing the rear tires on my car, I noticed some vibration over 130mph. I torqued the lug nuts to spec, and the vibration went away. None were loose, some were too tight.

For those you who don't have the issue, I'm happy for you, but do you really want to play Russian roulette with a car purchase? I cannot more emphatically stress how bad of an idea it is to buy this car. It could develop later on and they cannot fix it. Mine was totally fixed and came back a few days later. I think many people don't notice it. They will when diffs and trannys begin to fail. If you really want the car, and I get it, I love it too, go ahead. But consider yourself warned.... I have driven 4 S550's and 3 of them had the issue. The entire platform is cursed. I would pay to have it fixed, I can't do it myself. The car can't be trusted once out of warranty. A transmission job is $7000.

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.

20k miles no issues. Taken 3 800+ mile roadtrips fine
