re: Centre-Lock Wheel Recall For Porsche
Friday 17th June 2011
Porsche has announced a recall for its more potent 911 models as the cars' centre-locking wheel hubs can apparently fall victim to premature wear.
Centre-Lock Wheel Recall For Porsche
Porsche gets to the hub of a wheel wear problem for some 911s...
As a result Porsche is recalling 911 Turbos, GT2s and GT3s with single-nut wheels in order to replace all four hub assemblies with an improved (and hopefully non-wearing) version.
The recall affects 1702 cars built between 18th May 2009 and 17th September 2010, and owners of affected cars will soon be notified.
Thinking about it, we've got a Porsche Centre lock in the PH office acting as a paperweight; hope fully that won't need to go back to the dealer...

..Quelle suprise.. ! Centre locks on a road car was a stoopid idea to start with, this always happens, when will manufacturers learn...?
They need 600ft/lbs+ to keep them from coming lose, a torque multiplyer or a 7 foot pole, and that's most inconvenient for everyone involved, OPC's + indies, let alone the guy on the hard shoulder with a puncture, a wheel brace and a headache..
Racey looks are a piss poor trade off against safety on a road car IMHO, and I'm a Porsche nut.!

the pic says 500 nm... thats only 368.73 lb/ft, no wonder they keep coming loose if thats what you say they needEdited by RatBoy M3CSL on Friday 17th June 12:12

Too right, that's why Porsche are recalling the cars and replacing them with a slightly different design of the same nut... oh hang on.They need 600ft/lbs+ to keep them from coming lose, a torque multiplyer or a 7 foot pole, and that's most inconvenient for everyone involved, OPC's + indies, let alone the guy on the hard shoulder with a puncture, a wheel brace and a headache..

It's a shame they didn't come to you first for advice, that's for sure.

They do look nice, but they're a PITA to get off. We had one at work for a bit, and it took the biggest guy in the workshop bouncing up and down on the end of a 7ft long pole to shift it!
A friend of mine works for a Porsche body repair centre and said something similar, they ended up sending the car back to the dealer to remove the wheels!..It's just a piss poor idea off the bat.. a 5 off M12 stud pattern is what you need..!, and forget racey looks on a road car.., and as for a 'speed' feature to change the wheel quickly.. forget it, how long does it take to send the car back to the OPC for them to take the wheel off and return it to you, a day..? now thats a fast wheel change NOT.. they did a recall on the GT cars that find their way to the track and had to be done up to 550nm I believe..
I worked on the XJ220 project, we used 700ft/lbs on those.. but it was a 70mm thread.. a hopeless idea all round, the cone angles need to be soooo accurate to get them to lock on, and the fact of the matter is with disimilar metals and thermal characteristics they will always come lose... and 'not a lot of people know that'..

Nobody said anything about the nut coming loose...
It's the hub design that's failing under load.
Except that, when Sabine Schmitz had a shot of ph'er RDMcG's GT3 RS she insisted that her mechinics checked the centre locks first, as they had had some previous bad experinece with them coming loose...It's the hub design that's failing under load.
