You don't need crack detection spray to see that!

2016 Range Rover Autobiography SDV8 Mariana Black

Hi all. I can add my 2016 car to this list of cracks. Fortunately it was a crack and not a failure! I regularly check both knuckles for these cracks with no sign of anything one month ago but on 19th August I spotted a crack on the nearside - these develop fast!
I contacted my local MD and was referred to JLR Customer Care as my car is outside of JLR's recall VIN range. JLR Customer Care opened a case and asked I book the car into my local MD for inspection. What JLR could not do was give me any assurances that this would be covered by the recall because the VIN is outside of the range, despite displaying the issue which prompted the recall....
In the meantime they wanted £240 to carry out the inspection and the car for two days. My issue is that the Range Rover is my only car and that I could not continue driving with the risk of a failure, obviously.
It was the lack of assurance that prompted me to replace the knuckle myself. The inspection cost alone goes a long way toward the cost of the knuckle.
I did the work myself and it is all pretty straightforward, with the correct tools, and I will also add that the driveshaft also needed replacement as was well and truly STUCK in the hub! 12 tons of vertical press could not even begin to persuade the two to part ways!
In the end I could have faced the cost of the inspection, knuckle and driveshaft plus LR's labour rates. I realise that I cannot expect JLR to help me further with this particular case but I do not have a full MD service history or warranty to jeopardise so the risk of the high cost made my mind up to resolve this myself.
I have also lodged a Vehicle Safety Defect Report with the DVSA. When I explained the steps I took to JLR Customer Care they did not seem surprised and reminded me that they may need to inspect the removed knuckle as part of the DVSA's investigation.
One final point. Ignoring the reasons for my own decision to avoid the risk of JLR not covering these costs I will say that dealing with JLR Customer Care has been a positive experience with responsive and polite staff answering my calls and emails.

Any progress with JLR Poland?

oooooops... normally I like cracks.. but not this one!

noooo way I'm going on the Autobahn home with this. Left it at the dealer abroad, and took the plane home. They will let me know.... fingers crossed. By the way: 2015 and in the VIN range.

I checked last year, no crack, and now, this crack. It develops fast!

How are you getting on "Robbie993"? As this is not a UK registered car I wonder if the UK recall applies, even though it is within the VIN range..

So, the fix now, is to fit a clamp over the top of the knuckle, so you can't see if it's cracked

Interesting, looks like it will be very close to the tyre.....

Not being on the list but with a 2014, do you know if you can you buy these and fit yourself to strengthen it up...? Pete

That looks like a very sexy clamp. I want one, or two..

Surely the idea is to fit these clamps to knuckles that are not yet cracked.

This bracket may be designed to give the additional strength necessary to prevent future cracking. I see the date range is still 2014 to 2016. FFS.

I'm not an engineer, but this looks like recognition that the original knuckle design was just a bit crappy.

I am an Engineer (Mech Design) and there are a couple of possibilities for the failure.
As previously mentioned galvanic corrosion, or simply the incorrect grade of material was selected or no FEA was done on the component.
My car was registered in July of 24, so it falls outside the affected component assembly date from 01 Oct 2014 to 2016, one less thing to worry about!

That bracket won't strengthen the casting as when the break occurs the broken piece moves inwards which is why the crack can be seen. The bracket will only prevent a broken piece from falling out if the 5mm bolt and thin sections of bracket can be trusted to hold it in.

This approach is reminiscent of the Defender front axle issue (failing weld) and eventual recall N706 which also involves fitment of two clamps to hold the axle together and stop the wheel detaching in the event of failure, opposed replacing the defective parts. Jonathan

So now the integrity of the whole knuckle joint relies on a 5 or 6mm bolt in shear. You couldn’t make it up. Given that fitting these will constitute a modification and you will be obliged to tell your insurers l wonder what their reaction will be. Imo JLR need to go back to basics and redesign the whole joint.

Insurer, What’s the purpose of the modification.

You, To hide the crack that forms in the two front top knuckle joints so that when one fails it will stop the wheel flying off when I’m driving down the motorway at 70mph.

I wonder if they'll just post them out like they did with the sleeping batteries

For our foreign friends - it's also worth noting that the first image Mikey posted says Global Recall Action at the top right

I noticed that Rangeroverworld offer an aftermarket solution that claims to fix this.

This might be an alternative for those of us with the same issue outside of the recall range. Does anyone have any experience?

These new brackets from JLR are £221.37 each plus VAT so a total of £531.28

Hardly a cheap alternative...... Pete
