Hi All.

The summer is here and I'd been planning to referb my alloys, so as were predicted a bit of a heatwave for the next week or so I started to take the first wheel off only to find one of the dreaded chrome nuts has snapped off...! Now Ive got to face 2/3 hours of trying to loose the broken nut.
Has any body come up with a way to prevent these nuts from breaking? I'm going to clean the threads up and replace the nut again, but this is the 3rd one to fail in this manner since Ive had the car, and no matter how much I clean and look after it these nuts just seem to constantly fail, even when set to the correct torque.
Had a mobile tyre fitter replace the tyres last year and even after torqueing them down (so he said) it still happens.

 

no have about 10-15 minutes work if you go buy a 3/4" metal hole saw and take out the center drill bit. Fits right over stripped and broken lugs and cuts off the nut through the shoulder and doesn't damage the wheel. Then take off the wheel and the remaining piece comes off by hand. Spray with lube just about constantly while cutting. Do this several times a year on all Jagars

 

Replace the "capped" OEM Jaguar lug nuts with one piece ones =

This one sits shallower and requires changing your SEPARATE socket and breaker bar to remove them to 21 mm.

Chrysler part number is MB579290.

Normal 19 mm replacements =

Gorilla (gorillaauto.com) #73138T

Dorman #611-117

 

Thanks guys, those are the best idea Ive heard on both fronts. Ill nip down to my local screw fix and get a drill saw, and check the Chrysler wheel nuts out too.
I read on another Jag thread using a plastic plumbing pipe to shroud the drill bit offers another layer of protection to the wheel when drilling these nuts off although they didn't come up with such an ingenious use of the hole saw....

Will update as on going as I feel Ill no doubt find more nuts in the condition as I move onto other wheels.

 

Those pretty nut shaped caps that are on there, that "strip out" are just that, chromed sheet metal caps. I took a screwdriver and a hammer to the chrome part and found an actual nut underneath. It is too small for the factory lug wrench to work on, but a proper size wrench will take them right off. I did however replace all of them with solid lug nuts, cause who wants to have to go thru all that. By the way, I carry a socket that fits the inner nut, and a couple of my left over nuts, just in case I see a stranded Jag along side the road, wish I'd have had access to the right socket when mine stripped at 3 in the morning, cause I got the cover off, but was still dead in the water since my oem wrench(practically worthless in all regards) would no longer fit.

 

Im coming round to the idea of replacing the nuts with solid ones as effectively Jag have simply placed a sheer nut on the wheels and like you say if you're out in the middle of know where and one goes you've got a real problem. I must admit though they do look very pretty against the black wheels lol

 

Searched high and low for the size of the nut under the metal case on the lug nut in the full workshop. There was no spec. Nut with cover is 19mm but what is the size when you strip away the metal shroud?
