One of my locking wheel nuts has gone faulty.

Do you think I have any chance of Jaguar supplying a replacement of the one nut ?

Also, where can I buy a regular set of nuts to tide me over...Halfords seem not to stock...do I have to deal with Jag only ?
 
Not at the time of posting, ...had just been told 3 minutes earlier by the tyre center that a locking nut had failed.

I guess I'll find out Monday when I call the dealer.
 
SB Wheels are a good source of supply. Actually, I just remembered I bought a set of 4 standard nuts from Rimmer Bros. -£25.85 inc delivery.

Can non-jaguar suppliers supply the locking nuts or just ordinary ones ?
 
SB Wheels has at least one black set ... https://www.sbwheels.store/product-page/xe-xf-f-type-xj-xk-locking-wheel-nut-set-black
 
The standard fit Jaguar wheel nuts and locking nuts are a terrible design and prone to fail as the metal inside corrodes and separates from the outer casing and I’ve replaced these on both Jags I’ve owned,
I replaced the locking ones with the jag after market ones that @scm links to above and non locking with the expensive Jaguar solid metal ones with the Jaguar logo on. Other much cheaper options can be found on eBay.

It may be that the standard nuts only fail after a number of years, so many of us haven’t experienced it yet - but over on another forum XK owners are quite vociferous about the issue.

IME, Jaguar will only supply a set of four lock nuts, complete with locknut key. Most dealerships can obtain them within 24 hours.

I'd also suggest the design is only likely to "fail" if it is abused by some air-powered tool, or a monkey-with-a-wrench....
I'd be asking the dealer(?) what they were doing to have the nut fail; was the locknut properly located/seated on the head of the bolt?

The earlier two-part locknut referred to in another post is not standard fit (and hasn't been for some time AFAIK).
 
Agreed that over torquing with air tools or no care will bring on the failure; but I suggest the underlying 2 piece design (not the seating washer, but the alloy cover over steel) is the root cause.

James, I just can't see how it can fail - although there's often no accounting for human ingenuity.
So long as the locknut is seated fully onto the two-part design, its foolproof.

It's more likely to have been inadvertently damaged, or the wrong code key used (some code keys are a very similar pattern).
 
It is the domed cover on the locking nuts and the hex chromed cover on the non locking nut- this is bonded to a steel core which corrodes and can detach from the cover so it turns and doesn’t unscrew.
Had this happen on a locking nut on my XK and had to spend a fortune getting it drilled off. It looked fine and was correctly torqued, I’d done it myself. (It might have been weakened by previous bad treatment)
I’d suggest the solid metal options are superior.
 
Your description is pretty good! I've got the T-shirt too but for different reasons - DAMHIK.

The bonded chrome cap on the locknut also has the key pattern which 'follows' into, and replicates, on the shank of the nut itself (I hope that makes sense).
The two parts should not move independently of each other. The key nut should properly locate onto both parts of the nut - if it hasn't been located correctly, then trouble starts....
 
Interesting, I think I’ve still got the damaged lock nut, the corrosion inside was so bad that there was no discernible sign of a lock pattern, the domed cover was clean outside and looked as good as new, no damage to it so key still fitted perfectly, just didn’t turn the rest of the nut that was still on the wheel….
