2012 Defender 90 Puma 2.2 CSW Santorini Black

Much have been said on how this intermediate shaft wears. One of the hypothesis is misalignment between the main gearbox and the transfer case. This is what I also think being the culprit.
If there is some sort of misalignment then I think having another set of splines is better as they allow a bit more of movement.
If wear is unavoidable, then I want to have the wear on the cheapest and easiest part to replace. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

Popular opinion among those that have looked into the problem, is that there is an alignment issue between the gearbox and transfer box on the vehicles that have a short shaft life.

If this is the case, fitting a one piece shaft will cause wear in another area. Either the gearbox output or the transfer box input, rather than the connection between the original 2 piece shaft and socket.
How long it takes for problems to arise in the other areas remains to be seen.

The only certainty is if you've had the problem once, and do nothing to fix it, it will happen again.
Good luck with whatever option you go for!

Thanks Dinnu & DSC, that clears it up for me.

The misalignment would also explain why many Pumas never suffer from this issue, while others do - LR's typical 'build quality'

Well, seeing that the LOF one is out of stock, I will end up buying the Ashcroft kit as my Puma is going into the shop next week for some transfer case TLC.

Corrosion alone would also explain it , since we all know that some cars having corrosion issues don’t pass the MOT while others never suffer from these problems.

To all the Ashcroft upgraded shaft guys, how does it look 4 to 6 years after? Making my Defender great again. (Or trying to at least xD)

How’s your LOF one piece shaft performing ?

At 70k miles I’ve decided to drop the transfer box and have a good look at the adapter shaft.

if it’s worn I will replace and so it will be Ashcroft, LOF or IRB decision time. Genuine shaft and cup with grease or genuine shaft and cup with a grease nipple in the cup and drilled adapter housing I’ve discounted.

I’m aware of all the pros and cons of all the options, just wanted some up to date feedback on those that have fitted the one piece LOF solution, in particular how many miles they have achieved and any issues with the MT82 and / or LT230 box’s.

I’ve got the LOF unit in our 2.2 Puma. It hasn’t covered that many miles since the conversion, but so far there have been no issues with anything in the transmission. Charlie
