I know I'm pitching in quite late on this one, but for the captive nut to be pushed down off the underside of the roof panel, all the down force must have been via the bolt, and that to me means it wasnt tight (as if it was, the nut would be compressing the roof panel between the nut and the rack the other side. Or has it cracked the roof panel all round the nut? Am I missing something??

158 lbs is about 71kg Mike

The roofs outer skin was not damaged, only the inner sections to which the captive nut was atached. Mike

Yes I kow, I have been off roading with my rack and tent for 18 months and have covered over 20,000 miles off-road with it, before the current problem. I have already started looking at a Td5 Defender for my more serious trips as from past experience the full length gutter rails on the Defender are more than capable of taking the load (even if Land Rover don't think so). I wish I had never sold my beloved 2002 Defender 90 Tombraider, she may have been noisey and uncomfortable but she was a lot more reliable.  Mike

According to LandRover you will be exceeding the roof loading of the D3 regardless of what rack you fit, it will invalidate your warranty if you exceed the roof loading.
I was at Stoneleigh Land Rover Max show this weekend and the question of Insurance implications came up if exceeding the manufacturers roof loadings - an even darker an area that I don't want go down and had not realy considered till the question was poised! Mike

Another reply from Land Rover - they have fired back the website disclaimer for the discrepancy of the weight loadings of the luggage rack, I quote "...we do not represent or warrant the accuracy or completeness of information on this site.." so they are quite happy to mislead the buying public. They have however passed the issue onto the Product and Marketing Team  what good that will do....I wait to see.
They are unable to find any reference to the vehicles roof loading in the owners manual, so how are we to find out this information. I suppose we could ask, but then they don't want us to know how C  the loading is.
I think I will send them one more letter, then try one of the magazines to get this whole issue of vehicle roof loadings raised. Mike

I've been on my hols for a few weeks, and have just read all the posts that have risen since it posted the pic on the first page.
I'm not aware that my D3 is a special one off or that it had any re-enforcement done to the roof supports areas.
I'll pm you my vin number to see it helps the process with LR.

Hi Lee Land Rover will not supply me with the build details on your D3 as I am not the owner..Data Protection Act... so if you want to know you will have to find out from them if your load plates were fitted at manufacture. Mike

Roof Load is not on the specification list (page 269 - 274) in the official owners manual supplied with the vehicle, all the other information is as stated in your page link. The owners manual I have is part no LRL 10 02 53 802 and several of my friends have been through it and are unable, like Land Rover to find the information.
Page 275 in my manual is the first page of Type approval, what year model D3 is yours and what is the part number of your owners manual? Mike

Have LR answered the question about the fixings? I think that is where the problem is. Difficulty is getting LR to admit a build failure. You will need some proof.
What details of build do you need as I can ask the dealer on Monday for mine as I have the same fixings as Lee.
I still think the guys following theis thread should look at theirs and if they are all the same you have sometng to throw at LR.  “There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

Unnecessary quote removed
They are unable to furnish the information on the build details of Lee's vehicle as they would be breaking the data protection act. If you can find out from your dealer that would be great. The only comment their engineers have made is that the roof loading would still be 75kg/50kg in any case as they have not amended the roof load figures during the manufacture of the D3 regardless of any modifications.

I'll see what I can find out.
You are on a hiding to nothing talking about loading.
You need to get them to admit that the fixing was a manufacturing fault. They are using load rating to get out of the claim.
Especially with photos of the G4s you can argue you have a "reasonable expectation" (legal term) of the roof rails coping with the load you placed on yours. "reasonable expectation" is why they will pay for failures outside warranty. “There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

the info came from Land Rovers own website and has always been there and the info is still the same as it was 4 years ago. http://www.ownerinfo.landrover.com/extfree2viewlrprod/index.jsp

Because no one has said they have the same fixing as MELISCAT(nut only without spreader plate)
Never said I had any proof I just said I think it is what he will need to proove.
Have you checked what fixing you have CW?
IMHO his fixing is not fit for purpose so not surprised it cause the cracking. The fixing would create a point load leading to metal fatigue insteasd of it being spread out. “There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

A couple of us have asked the question, which has been ignored - how can a point load be created on the rail fixing bolt, unless the bolt is loose AND a load is applied directly to the bolt head?
Even if the fixing bolt is loose and there is a load on the rails, how can it possibly be forced downwards? The rail fixing bolts simpy hold the roof rails against the roof. They do not carry the load, which is spread along the length of the rail
