Differential or transfer case failure on the 2005 Toyota Tundra
Only 6 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When differential or transfer case failure gets reported
There are 9 reports of differential or transfer case failure on the 2005 Toyota Tundra, 6 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 110,000 miles. It is the 12th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 105,000 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 11 model years of this car. It shows up earliest on the 2008, at a median of 5,000 miles, and latest on the 2004 at 110,000 miles.
By volume the 2004 carries the most reports, with 48; the 2005 has 9. 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 2005 toyota tundra. While an independent mechanic was inspecting the vehicle, the mechanic observed that the rear differential was severely corroded and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 75,000.
The differential housing rusted through so that the lubricating fluid leaked out onto the road. This happened both when the truck was moving and at rest. Toyota had already replaced the vehicle frame as rapid corrosion and rusting caused a recall. The differential transfers power to the rear wheels so the lack of lubrication could have caused the rear wheels to lock while driving with the potential for a rear end collision or complete loss of control at high speed. Used replacement differential housings are unavailable because of high demand due to failure of originals due to rust.
I have a 2005 toyota tundra, which has the entire frame all rusted. I already replaced all brake lines and differential because of the rust. The mechanic said it is rusted so bad that it could fall apart. There was a limited campaign for a recall on our tundra and the spray was done in 2015. Obviously it didn't take because of all the continuous issues we are having. I called the corporate office of toyota and opened an claim and the manager I spoke to really could care less and told me that once the warranties are over its no longer their (toyota) problem. I requested a field inspection technician to look at the truck . That request was denied by the manager who stated that he was speaking for toyota. I asked for my claim to be reviewed by some one above him and he stated their was no one higher them himself and his decision was final. I don't understand why they can't look at their products and tells us if it is safe to drive. Obviously they new there was a problem or they wouldn't have the limited campaign for a recall. They need to do more.

How far this goes
This page is kept out of search results because 9 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 9 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 2005 Toyota Tundra?
Across 6 owner reports that included an odometer reading, half were filed by 105,000 miles. A quarter were filed before — and a quarter after —. 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 2005 Toyota Tundra?
9 reports have been filed with NHTSA, about 0.1 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.
