rounded alu wheel nut

[redbull]

I have a very troublesome rear wheel nut failure in that it has become flakey and the 19mm socket spins on the nut now and i cannot get it off .has anybody conquered such a feat if so i would appreciate the knowledge of how u accomplished it?

Careful aim with bolster and club hammer -watch your fingers!!

I had a similar problem when a wheel nut sheared off whilst the local tyre company were trying to remove the wheel to change the front tyres. The part of the nut with the flats sheared leaving a small section holding the wheel firmly in place. The car, however was drivable, and I got it to my local Indy (Ray Northway). The removal didn't seem much of a problem to them and I believe they used a 'special' drill/grinder which just removed the remaining part of the nut. I think it either screwed onto or rested over the wheel stud and thus avoided damage to the wheel. I was really concerned about the wheel getting damage as they had only been refurbed a few weeks before, but there were no marks at all.

I don't know if the 'tool' is a standard tool or something fabricated by Northway's - if your local Indy doesn't have something similar it might be worth calling Northway's and finding out where they got it from. I don't remember the cost but it wasn't high and certainly a lot cheaper that having to replace a damaged wheel!

Kind regards

I would try one of the sockets that you can get for removing locking wheel nuts without the key. It's basically a socket with an anti-clockwise tapered thread that screws on to what's left of the nut. As it screws on it tightens against the nut, eventually turning and removing it.

Wouldn't recommend drilling it out there was a post on here about six months ago on that subject and I believe he knackered his wheel.

That makes much more sense than drilling - maybe that's what Northway's used - whatever they used it left no marks at all on a newly referb'd wheel.

When I think about it, the problem in the post I referred to earlier where the guy drilled out the nut was very similar to yours Anton. Did you have non-Porsche nuts on?

One of the big suppliers (I can't name them as the moderators don't like it [] ) supply repro nuts that aren't quite the same profile at the base as the original and there was a question mark over whether they would secure the wheel to the correct torque because of this. There was also some doubt whether the alloy in the repro nut had the same make up as the original and perhaps this caused the failure when being removed.

So the moral is "when you buy the replacment wheel nuts make sure they are original Porsche" [8|] .

Can't be sure if the nuts are original although I bought the car when it was about 3-4 years old (from AFN) and I haven't changed them. I would agree that there seem to be some real horror stories about 'non Porsche' nuts and I'd always replace them with Porsche items. I was told that, even the Porsche items, will fail over time so I can't be sure if the wheel refurbers over torqued the wheels or it was just going to fail anyway. Either way it wasn't a big deal to sort it out - however had I had a flat it would have been a completely different story!

Kind regards

Can you Knock a slightly smaller bi hex socket onto it .It might just grip enough to get it off.3/4 AF ?
