Other suspension problem on the 2011 Ford F-350
1 fire 1 injury 2 of the 34 reports for this failure mention a crash, a fire, an injury or a death. Those are the owner's words on the complaint form, not a verified finding, and one report can mention more than one.
When other suspension problem gets reported
Owners of the 2011 Ford F-350 report other suspension problem at a median of 62,500 miles. A quarter of the reports come in before 25,000 miles and a quarter after 135,000 miles, from 27 reports that carried an odometer reading.
A part like this is normally expected to survive 100,000 miles. It is the 2nd most-reported problem on this model year.
The mileage distribution
The reported range runs from 17,500 miles at the tenth percentile to 170,000 miles at the ninetieth, a spread of 151,925 miles across the middle 80% of reports.
A spread this wide points at use rather than design. Towing, climate, service history and city mileage all move a failure like this, so the median is a weak guide to any individual car.
30% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 17,520 miles | 26,182 miles | 63,000 miles | 135,000 miles | 169,445 miles |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Of these reports, 1 a fire and 1 an injury are mentioned. Owners write their own complaints and the agency does not verify them, so read this as what the reports say happened rather than as a confirmed count.
Putting it right typically runs $350–$2,000 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
The same failure on other years
The same failure is reported on 14 model years of this car. It shows up earliest on the 2002, at a median of 30,000 miles, and latest on the 2009 at 140,000 miles.
By volume the 2012 carries the most reports, with 58; the 2011 has 34. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
Tl* the contact owns a 2011 ford f-350. The contact was driving approximately 65 MPH over a road bump when the vehicle began to vibrate violently, causing the vehicle to travel into another lane without intent. The failure recurred three times while driving over a road bump or pothole. The contact planned to take the vehicle to an authorized dealer for diagnosis. The manufacturer was made aware of the problem. The approximate failure mileage was 23,400.
Tl* the contact owns a 2011 ford f-350. The contact stated that while driving 40 MPH, the front end of the vehicle started to jerk violently. The vehicle was not taken to the dealer. The manufacturer was made aware of the failure who referred him to the dealer. The vehicle was not repaired. The failure and current mileage was 23,500.
While driving in the left side passing lane and coming up to a slight left bend in the road the truck went over a expansion joint in the road, if there is slight pressure on the steering wheel from holding the truck into the left bend in the road the trucks wheels will start to shake and wobble, it will get so bad you need to hold the steering wheel with two hands and guide the truck to a complete stop in that left lane so to make it go away. This is real scary. I know there is items on the web sights that will fix this problem, but ford will void your warranty if they find any aftermarket parts on the truck. What I don't understand is ford knows there is a problem with this wobble and if you go and fix it they void your warranty. *tr

How far this goes
Complaints are voluntary, so 34 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does other suspension problem happen on the 2011 Ford F-350?
Across 27 owner reports that included an odometer reading, half were filed by 62,500 miles. A quarter were filed before 25,000 miles and a quarter after 135,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other suspension problem on the 2011 Ford F-350?
34 reports have been filed with NHTSA, about 16 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
