Holy Crap!
Out of curiosity, how old were they? Looks like they've got some use on them. Mike |

No idea. I'm pretty sure they were manufactured this way since all 16 are just like this.

The factory wheel bolts have the VW stamp on the end. I just got through cleaning 26 of them to go to the plater. I have no way of spinning them to check them though.

These lugs were under four years old and have less than 30 thousand miles on them.
They were purchased on Ebay for about $60-80 if I recall correctly and were supposedly the correct seat for the Fuchs and were sold as hardened steel. These would have more than likely would have failed on me in motion. Thanks for the catching this Mark, you probably saved the car and possibly my hide. Can you check it this as a primary seat issue or just junky production. |

I had to check, I was pretty sure that based on the feedback on this board that I steered widely away from theadante.
It looks like I picked these up in 2008 from ISPWest VW AKA pimppride on ebay for $70. It looks like he is still selling them too. http://www.vwispwest.com/91436131501BK.html |

If you've got an email receipt, would you mind forwarding it to me? I'll contact them and at least let them know about the problem.

Good catch Mark. What made you think to check 'em?
I guess I'd better check mine (IMG:style_emoticons/default/sad.gif) ... (bought some 'previously owned' ones from a couple of World members) |

QUOTE What can you guess caused them to bend like that? Mayb not torqued down properly and came loose? Poor quality steel? or lower grade substituted for higher grade to save $$ (grade 5 instead of grade 8), or the hardening process was improper. Which I think is the point Mark is making? |

The way they are chucked up make them really look bad. They may not be as bad as you think. Try chucking on the thread (without damaging the thread) and put an indicator on the radius surface. You will get some runout but I'll bet it will be less than you think. The accuracy of the flats you are chucking on in relation to the thread are not nearly so important. In your setup, they are the reference.

ISP West was the place I bought Fuchs center caps from that didn't fit well, way too tight. I steered
clear of his bolts too and got genuine bolts used. 914 Rubber's fuchs center caps were perfect. Not happy with Pimpride/ISPWest in my experience..... |

No it's horrible.
Runout at the seat, nearest the flats 0.35mm (0.014") Runout at the contact patch worn silver by previous torquing was 0.55mm (0.022") QUOTE What can you guess caused them to bend like that? Mayb not torqued down properly and came loose? I'm doubtful this was installation or usage error. I can really only see this being a manufacturing defect (loose tolerances) because they are all the same. QUOTE Good catch Mark. What made you think to check 'em? When I was unbolting the wheels with an impact driver I noticed more rotational wobble than usual. If you were using a socket wrench you would never notice. Once I realized what was going on, you could easily see the problem when tigthening the lugs. You could see the gap between the bolt and the wheel would vary significantly while screwing it in. Every half turn the gap would go from small to big, then go back again. |

Mark, Looking at this new video, could they have been over-torqued causing a twist just at the head?

Seeing that last video shows that they are pretty bad. If they came that way or were bent later is unknown.

Wow....I'm looking to either replace the bolts which just don't look good (chrome is pitted) or switch to studs and lugs. This is obviously a concern to me. Any suggestions on where to get quality stuff? Or do I put it up on blocks and have them rechromed? (IMG:style_emoticons/default/confused24.gif)

I just ordered a set of german OE lugs to try out. These are not Porsche lugs. The original 914 number is NLA, but supersedes to a new part number which is out of stock.
I'm pretty confident these will be of good quality, but will check them out regardless... |
