Differential or transfer case failure on the 2004 Dodge Durango
When differential or transfer case failure gets reported
Owners of the 2004 Dodge Durango report differential or transfer case failure at a median of 142,500 miles. A quarter of the reports come in before 120,000 miles and a quarter after 175,000 miles, from 26 reports that carried an odometer reading.
A part like this is normally expected to survive 110,000 miles. It is the 13th most-reported problem on this model year.
The mileage distribution
The reported range runs from 100,000 miles at the tenth percentile to 190,000 miles at the ninetieth, a spread of 89,000 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.
0% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 101,000 miles | 120,000 miles | 142,500 miles | 174,000 miles | 190,000 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
Putting it right typically runs $900–$4,200 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 12 model years of this car. It shows up earliest on the 2003, at a median of 30,000 miles, and latest on the 2004 at 142,500 miles.
By volume the 2005 carries the most reports, with 104; the 2004 has 27. 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.
Purchased vehicle on 2/19/13 drove it for 2 weeks. Was driving on the highway and heard a loud noise followed by clunking noise which sounded like a flat tire but wasn't. Took it to my mechanic who told me that the front differential needed to be replaced. Fixed that problem. 2 weeks after that on 3/29 was getting off the highway when I heard another loud noise followed by a clunking noise this time I lost steering and barely made it into a parking lot. Had it towed to my mechanic to find out it blew a rod and needed to have the engine replaced. After having this vehicle for 6 weeks I have had 2 catastrophic failures. My dealership will not help me and I cannot afford to replace the engine on my own. I purchased this vehicle to be a safe and reliable mode of transportation for me and my 4 children. Now I am out $6000 and have no vehicle. Something needs to be done about this. People should not be forced to pay for an issue that is known to be a problem. *tr

My well-maintained 2004 dodge durango slt began doing something bizarre a few months ago at about 120,000 miles. This has 4.7l v8 and the AWD-4hi-4lo 2-speed transfer case. The "service 4WD" and the traction control light began flashing, and it felt like the transfer case was stuck in 4hi with the tires grabbing on a turn. The selector knob on the dash would not function. I brought the truck to my mechanic who checked the function of the transfer case motor, inspected the motor and wiring, and changed the transfer case fluid again. I called my local chrysler dealer and they advised that they would need to change the transfer case motor. The motor costs $1190 plus two hours labor and two quarts of atf+4 fluid. I brought the truck back to my mechanic and he said there is nothing wrong with the motor or the transfer case or the dash selector knob. He said he believes this is a control module or programming issue. I got a third opinion at my local lee myles. They concurred that there is nothing wrong with the transfer case motor and there must be some issue with the computer, programming, or one or more of the control modules. The…

How far this goes
Complaints are voluntary, so 27 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 differential or transfer case failure happen on the 2004 Dodge Durango?
Across 26 owner reports that included an odometer reading, half were filed by 142,500 miles. A quarter were filed before 120,000 miles and a quarter after 175,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is differential or transfer case failure on the 2004 Dodge Durango?
27 reports have been filed with NHTSA, about 0.2 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.
