Hello Bluest
One approach if you can arrange it that may help, even get straight to the issue (or issues) is to find a good garage (Land Rover independent specialist would be ideal) get the Puma up off the ground on a lift so you can walk underneath it. The garage should also be able to lift the vehicle up on axle stands (the slide in type designed to work on the lift) this means that the Land Rover can be 'driven' rolling road like but in fresh air. If they are good, they will be able to roam around underneath and locate the area giving trouble... 
One word of caution...they should check... (you should check if there) that all tyres are stone free before they are spun up... 
I have done this twice once to confirm recently a wheel bearing and previously a universal prop shaft joint. Good Luck SKIP https://www.defender2.net/forum/topic83242.html |

Thanks X4. That’s probably the best approach, but am concerned that it won’t show up as it doesn’t happen at low temps. Even in the warm the car needs to on the motorway for 20 mins plus before it starts to make noises. I don’t have a trusted specialist either, which is a separate problem. 2007 110 TDCi Station Wagon XS

Noises like this can be incredibly hard to track down, at least until something finally breaks.
From the description my immediate suspicion would be that you have a bearing breaking up in the gearbox. Do you notice any additional vibration through the gear lever when the noise is happening? |

About this time last year my Disco2 (at 200k+ miles) started making a noise which matches your description almost exactly. Since it was impossible to track it down, I lived with it until earlier this year when, in the course of one journey, it suddenly became very much worse, quite alarming in fact, at which time the gear lever also started vibrating significantly whenever the noise was occurring - vibrating enough to be uncomfortable to hold. This confirmed my diagnosis of a bearing in the gearbox failing, and a replacement gearbox from a breaker has cured the problem.
I haven't yet stripped the old box to find out what has actually failed, but I suspect that the intermediate bearing on the mainshaft is breaking up. |

I've had this type of noise twice, once a failing rear diff input bearing and once a seized UJ. On overrun it sounded like dropping a bag of bolts into a blender
Take one prop off drive it to see if it changes. Only appearing when warm could be due to treacle-like diff oil absorbing the noise. LR Workshop Find a Defender's history and spec: https://defender.lrworkshop.com |

Thanks Will. I will try that, although the need for hot weather for the issue to manifest may limit what I can detect. I may also just change all the UJs as a matter of course as I don't have any record of them being renewed in the past. There's no obvious play in them, but you never know.
Regarding the axles. Is there any way I can check the health of the input bearings, by checking play or end float or anything? 2007 110 TDCi Station Wagon XS |

Basically I put pressure on the diff flange in different directions whilst turning it to feel for roughness, but certainly you don't want there to be any movement of the flange up or down, side to side or in and out. LR Workshop

It's worth being sure the diff nose pinion bolt / nut isn't loose too and no movements in the flange as mentioned I think above.
It sounds over simple but as with other things it can often be the smaller cheaper things. (Hopefully!) that are the culprits. Everything cheaper, and easy access is worth checking before delving deeper. And Prop UJ's and take they off the check as well, because they can be difficult to find a failed UJ too. It could be many things and there are plenty of ideas here given, some easy to check others not so butt start with the easiest and work your way though each ite. Sometimes the smallest thing can seem like a really big problem. $W33T $0U7H3RN $UG4R

Maybe a quick squirt with a grease gun on the prop shaft yokes before you start removing prop shafts?

The UJ are all well greased, so I fairly sure it’s not that. 2007 110 TDCi Station Wagon XS
