I'm not sure if this helps the alignment theory or not - I had an Ashcroft output shaft fitted around 10k miles ago, after 70k+ miles the original was worn but had life left in it. Click image to enlarge I've just had an Ashcroft re-con transfer box fitted. Both the original and re-con transfer boxes slid easily into place. To my mind this indicates good alignment = over 70k output shaft life, tending to substantiate Blackwolf's alignment theory, that is to say that on mine MT83, LT230 and adapter housing are all within tolerance.

Yes - that's the worn 70k+ shaft I thought that was a good life! Compared to your experience it's not
I expect/hope that the lubricated Ashcroft shaft will be much better |

Well, to keep it in perspective, you have had ten times the mileage that some people get!

" that is to say that on mine MT83, LT230 and adapter housing are all within tolerance."
They may well be, all of the early failure 'boxes, adapters and shafts may also be with in the manufacturing tolerance. Wether those tolerances were correctly specified to make a product that has an acceptable life under all possible variations is another matter. There are 2 possibilities, 1) the system was designed with too much variation to achieve acceptable alignment and product life. 2) the quality control procedures failed to maintain the assembly with in its designed limits, if it was correctly specified. So the problem is either a design failure or a manufacturing failure. Landrover's fault and they didn't fix it. Pot luck as to wether you get a good one or a bad one is not good enough! |

This is mine at 55k... Splines are worn (although strangely some are not???) but out of the vehicle the coupling is surprisingly tight by hand considering the clunking!
It was changed at my request as I had the clutch done, so figured I'd do it whilst the box was out. Full write up on that coming soon...

Click image to enlarge Not too much live left in that one. It looks like my shaft that failed in the Alpes mountains. I don't believe the misalignement theory. Misalignement causes wear but it can be controlled so easily in the production line. And everybody can proof it. Why should Land Rover have taken such a big risk in a period of 10 years? I think it's the corrosion products being harder than steel. The corrosion products are the sand in the joint and they grind it down. The rise of temperature changes / load changes / periods of hard use accelerates the process. In the Alpes I stranded at the workshop of a technician for harvest machines. Each and every harvest machines has the same kind of joint in it (and it must be lubricated). If it falls dry it will wear and fail. |

This was mine after 38k miles.

My original Landrover output shaft went at about 13k miles, new one was fitted by Landrover under warranty but that one failed about 3 weeks ago at 29k miles which was lucky i was outside the house when it went.
I ordered the new replacement output shaft from Ashcroft for i think was £295+vat & delivery, downloaded the instructions off the internet and waited for the it to be delivered. The very next day the shaft was delivered to me, bearing in mind i had only ordered it at 2.30pm the day before, so thumbs up for that level of service. Waited 2 weeks for my friend who runs a garage for sick 4x4's to have the time to get my defender 110 but once it was there he had the part swapped out in a few hours. I asked my friend did he have any troubles with the fitting and he said it was straight forward to do. With regards to the performance of the output shaft itself, its solved a few issues that i didn't know were related. I have had an annoying judder while under acceleration, though maybe it was injectors or fuel related even after it's just had a service but turns out it was the output shaft as the hesitation has now disappeared with smooth strong acceleration. Second issue i had was an annoying rattle at tick over, i have been all over the vehicle replacing worn parts to only have the vibration vanish once the new Ashcroft output shaft was fitted. Well worth the money in my opinion & if it last longer than 26k miles I'm quids in. |

It looks to me like nearly everyone's output shaft is dry too.
I used to get before my most recent clutch change a bit of a grinding at low speeds too, I thought it may be the rear duff area but once the clutch was done it was gone. On the good advice of Blackwolf on here I asked them to lube the output shaft too which it was out. They said the flywheel was still good, so that was a good thing and the output shaft was okay too. This was & 42k approx. They lubed it all and its all been good, I would imagine if this wasn't done abd the clutch I had would have gone on the output shaft would have instead. I think they said as per usual it was very dry. Seems to me like a lot if things weren't lubricated from manufacturer! No Guts, No Glory. 🇬🇧🏴🏴🏴🇮🇪🇺🇸⛽️🛢️⚙️🧰💪 |

Interesting points regarding lubrication raised above. My 2016 model had the blue grease drip under the gearbox
at new, so land rover did seem to take note of this issue towards the end of the production run. I have only done about 16k miles since then but time will tell if my output shaft lasts or not. If (when) it fails then its an Ashcroft unit for me. |

I have just had an Ashcroft output shaft fitted. When my Defender was in for a service last year it was noted that there were rust signs coming from the transfer case - and indication of potential failure. So, as I am planning a trip to Morocco later this year, I decided to take the precautionary option and have it, and the clutch replaced. Once removed, the old shaft was clearly bone dry and rusting nicely. Euro-Leafing to infinity and beyond.....

The shaft failed and I lost drive at 12,000 miles on my 2012 truck . I was in France at the time on holiday.

Does anyone knows where is the geometry gone wrong? I have read Dave´s observations but I do not think they are conclusive. Maybe they are but I do not get it. Gearbox end, extension casing or T box? Puma 110" SW

Recently had the clutch replaced on my 2007 Tdci at about 88,000 miles. My local Independent advised having a look at the output shaft while they were at it. Turned out it was nearly ready to through in the towel so replaced it with the Ashcroft part. The drive is completely transformed. Almost all of the "slap" in the transmission has been removed and driving is a much more pleasurable experience. Just prior to having this work done I had the rear drive flanges replaced which also contributed to overall driveability.
