The only way that Land Rover could be "persuaded" to address this issue is if during the press briefing for the launch for the "new Defender" the Solihull man expounds on the advantages of the new front suspension system over the old fashioned live beam axle championed by Land Rover on the previous model i.e. existing model.
If a journalist then quips "Then that will do away with the dangerous fault in the old live beam axle with the axle flange welding issue."
Land Rover would not want their launch to be tainted with such an issue.
Now if you could get a journalist to contact Land Rover before the launch and raising this issue, they might address it to stop it rearing it's ugly head at the launch of the new model....if it ever materialises. 1982 88" 2.25 diesel

Le staffe in oggetto così come le fornisce la Land Rover NON SERVONO ad evitare che succeda questo :

Ma SERVONO SOLO ad evitare che succeda questo :

Cioè impediscono SOLO il distacco completo della ruota e il rischio di incidente ma NON evitano che la saldatura possa cedere.

Il problema che NON EVITANO che la saldatura possa cedere dipende dal fatto che le staffe in oggetto montate così come prevede la Land Rover non poggiano da nessuna parte per impedire il cedimento della saldatura (vedasi le seguenti foto) :

Rimane spazio tra staffa e flangia, tra staffa e bulloni, tra staffa e rondelle.
Le staffe in oggetto montate come previsto dalla Land Rover stanno lì per bellezza in attesa che si spacchi la saldatura.

Ho risolto questo problema nel modo seguente rendendo le staffe in oggetto UTILI ANCHE AD EVITARE CHE LA SALDATURA POSSA CEDERE :

Bulloni M10 x 60mm a testa svasata, classe di resistenza 12.9

Le boccole hanno il foro da 10mm decentrato in modo da incastrarsi perfettamente tra bullone e foro staffa :

Ogni boccola è risultata con il foro decentrato diversamente.

E adesso le staffe in oggetto EVITANO ANCHE che si spacchi la saldatura :

Unfortunately, I can’t speak the lingo, but it looks like you’ve used the the LR safety bracket things to actually strengthen axle to prevent it failing in the first place, rather than just stop if falling off when if does break. Thumbs Up 2007 110 TDCi Station Wagon XS

Yes, the change I published serves to prevent welding from breaking.
Thank you.

Wow - that is impressive engineering - especially making the offset pieces for welding in.

Very nicely done, but.....




.... I have to wonder if the work involved wasn't actually more that the work needed to beef up and reinforce the dodgy weld between the axle and flange. The most important thing is that is has sorted the problem and gives peace of mind. It is certainly a fine example of first class engineering.

I find it hugely reassuring just to know that my hubs can't pert company with the axle after I fitted the brackets, and still think JLR's attitude to this particular issue is shockingly cavalier. I wonder if the new Defender will be treated with similar disdain.

That's all very impressive, but with all that precision, using an angle grinder and drill press to skim down the screw heads made me chuckle. I think I'd probably do that bit with my lathe (of course it helps if you've got a lathe....)

I wonder if the owner does actually eat his dinner off that axle. I'll bet it was dirtier on the production line!

If a picture paints a thousand words, the above is the Encyclopaedia Britannica. Great effort. You're a man who takes his work seriously with lots of attention to detail. If that was mine I'd probably spend hours looking at the finished product and forget to drive it! 1982 88" 2.25 diesel

Any chance we can get the details of this in english and what materials are needed?

If this is a tad overkill, if I order the brackets, is it a straightforward installation?

As blackwolf said, this is a better safe than sorry kind of situation. This is critical where I am right now where independent shops are more capable and reasonable than the local dealer. Rolling Eyes Just to give you a clue, since my truck documentation got dunked (pages now stuck together) I tried going to the dealer to order a new set of vehicle and quick reference manuals early this year. They still haven't gotten back to me Rolling Eyes Whenever I meet them during shows, all I get is, "I endorsed it to so and so who should've contacted you" nope. Zip. Nada. Since this new group took over the dealership, it's starting to look like they are only interested in vehicles in the Disco 5 and above range. Legacy and Legendary units will have to fend for themselves it seems.

Fitting the brackets is very straightforward (although you need to remove the nuts from the radius arm bolts which can be a pain depending upon their condition, and access with tools is not great) and really doesn't take long.

The brackets are also intended not to mask a weld failure since they will allow the tell-tale oil leak, since it would clearly be a bad thing to drive about with a failed weld even with the brackets.

Whilst I admire the engineering effort which went into MarcoLauretano's axle it is not something that I personally would do. The brackets may not prevent your axle failing, but they will make it a safe failure, and that amount of engineering would in my view be better spent making the axle case itself stronger.

Since I'm not sure if my axles are covered in the recall (I suck at trying to figure out if my VIN is covered or not), I want to be sure that the truck is safe as I do take it off road and it is also my daily driver.

I recently dented the front diff cover so was thinking of getting the Gwyn Lewis weld on to make it tougher plus sumo bar gear for the steering as these are most definitely affected by the boulder I ran over trying to escape a flash flood. So yeah, fun. I'm still trying to figure out if that boulder hit anything else under there but it seems a new steering guard (a new plate type is due perhaps?), the steering rods and ends, the ball joint thingie in the rear suspension, and pound the rear right mud guard and the folding step back into shape and place are the most obvious things to work on at the moment.

So, would it be reasonable to conclude that the fitting of these two additional brackets would be a good idea as a precaution on a MY16 90 that's done less than 20k miles? Rob

I wouldn't drive a Puma without the brackets fitted.
