only just found out about issues with g box output shaft. Does anyone think if failure is preventable? Maybe remove transfer box to inspect/lubricate?

Also if from a certain year it was addressed by lr and say greased from 2012 onwards etc.

Pretty poor really especially for the guys that work their trucks for a living. Or say an aussie dude that facies a reccee across the outback!

Presumably you have the LT82 gearbox, which in common with all LandRover and Ford stuff, needs regular maintenance and oil changes.
Failure to use the 'correct' lubricant may lead to failure!
In the gearbox you should be using Dextron II ATF, and not grease!!

On the puma models is it possible to take the pto cover off the back of the transfer box, pull out the main gear and inspect the gearbox output shaft like you can on the earlier models?

For the Puma JLR specify Castrol BOT 130M or equivalent for the gear box. This is basically a 75W-90 fully synthetic transmission fluid suitable for "fill for life applications". (Life = 120k miles max). I have used Castrol Syntrax Universal Plus in the transfer box and will use it in the gear box when I change it. It can be used in the front and rear diffs as it meets GL4 and 5 but exceeds the spec as a basic mineral can be used here. So can be used in all transmission components on the Puma but is a bit pricey at £18 a litre.
I did read somewhere (might have been on Landyzone?) that some Pumas left the factory with the gear boxes only partly filled with oil. Which means that some / many could be short of oil for many years before the shortfall is corrected as a level check is not carried out as part of routine servicing unless a leak is evident.

The shaft being talked about is the adaptor shaft which adapts the MT82 output spline to the coarser LT230 input spline that we all know and love. It is located within the rear of the gearbox and to access it the transfer box needs to come off.

For whatever reason this shaft is coupled to the gearbox output in a dry fixing (i.e. not immersed in oil or splash lubricated like the LT230 input in later years) and many seemingly left the factory with little or no lubrication grease applied. As such the splines fret and eventually they fail and you loose drive.

Ashcroft Transmissions do a modification to improve the lubrication, however it’s quite expensive.

Thankyou guys for the sound advice especially oils etc as that will be invaluable once im out of warranty.

What would you do then to prevent failure?? Im happy to drop transfer box off to lubricate but the lr is still under warranty. I plan on keeping this lr and i know if i leave it the rascal it will fail a week after warranty finishes.

Fair play to mr ashcroft too, maybe lr should employ him to iron out crap like this on future models

The only permanent solution is to fit the Ashcroft modification.
