Other suspension problem on the 2011 Ford F-250 SD
2 crashes 2 injuries 1 death 5 of the 43 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-250 SD report other suspension problem at a median of 35,000 miles. A quarter of the reports come in before 27,500 miles and a quarter after 70,000 miles, from 39 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 7,500 miles at the tenth percentile to 100,000 miles at the ninetieth, a spread of 91,390 miles across the middle 80% of reports.
When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.
51% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 8,610 miles | 26,963 miles | 35,500 miles | 71,215 miles | 100,000 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, 2 a crash, 2 an injury and 1 a fatality 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 22 model years of this car. It shows up earliest on the 2013, at a median of 10,000 miles, and latest on the 2009 at 150,000 miles.
By volume the 2019 carries the most reports, with 634; the 2011 has 43. 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.
Front / frame vibration and bouncing after hitting a hole or at certain speeds that seem to be producing frame vibration due to a harmonic frequency generated by the tires and road speeds exaggerating an engineering defect in the front suspension. *tr
These trucks shake violently in the front end when they encounter even the smallest of bumps in the road. Ford has failed to take the responsible and corrective matters to fix the problems. Something must be done before someone get killed. Please see fordforum.org to see that many others are having the same issues. *tr
Below is a complaint letter that was sent to ford today. I previously filed a complaint with the NHTSA. So far they are holding my truck hostage and not fixing the problem. Please do something. It seems that there are many truck of this type and model that have the same problem. Please see fordforum.org under the heading of violent front end shaking. My 2011 f-250 has been at gus muchado ford in palmetto bay florida for the past 4 days for a wobble in the front end when you hit a bump. The dealer tells me that they are working with engineers at ford. The problem is that the mechanic can only email the engineer, he then has to wait for the engineer to read the email and respond. Then the engineer has to wait for the mechanic and so on. In the 4 days they have had my truck only 2 things have been looked at. When I was there this afternoon my truck was parked out in the back parking lot and not being worked on. When I asked why it was not being worked on they responded that they were waiting for the engineer to tell them what to do next. I desperately need for someone at ford to step up and take control of this situation. If this…

How far this goes
Complaints are voluntary, so 43 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.

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.
