It is a "heavy pull" but it works. I either don't like the feeling of torquing down nuts with a lot of power. But the stud and nut is designed for this. Just be careful that ýou really set the socket well over the nut and pull the bar with a slow and distinct move. On the porsche race cars from 964RSR and onwards you use a center lock nut insted of the 5-lug pattern we have. These are torqued with 460 nm/330 lbs all the time when the wheels are going on and off. It's the same dimensions like we have. So just be brave and pull the bar!

I use this method on my track car where they have shown to loosen even when torqued properly.

Anthony- are those nuts available from Porsche or do you use an m22 that you purchase on your own..

Thanks all for the advice re torquing, but that's not really my problem. I figure that with the 18" breaker bar coupled with my weight, I applied a max of 200 ft-lbs,which was done by just pushing down with my hands/arms, not standing on the end of the breaker bar. My torquing came abruptly to an end at that point - It felt like to me that the nut had reached the end of the axle's threads. My fear is that torquing it to the required 330 ft-lbs might strip the threads on the axle. So my question to all is, am i being too paranoid and should just go with a longer breaker bar to get the required 330, or am I doing something incorrectly or have left something out causing the nut to bottom out too soon.

Yes. You didn't get to the end of the threads. That's not possible.

You can back the nut off and look. Long and short is, you won't get anywhere close to the right torque with an 18" breaker bar. 330lbs is huge. I use a torque multiplier and a 24" torque wrench when i do it.

The only time I have seen a situation where you reach the ends of the threads is when someone used cheap aftermarket Chinese made drive shafts and the material was inferior. It kept stretching the shaft until their was no threads left. I am assuming this is not the case? I would find someone with a proper torque wrench or pay someone it isn't worth taking a chance. ceased bearing or failed shaft can make for a dangerous situation.

I use an m22 I get from a local supplier.

Just use a proper torque wrench. You are making this much too complicated. And if the threads stretch (which I highly doubt), then you need a new axle.

Thanks all. I've decided that I'm just being ridiculously paranoid. Going to take it to my buddy who runs a diesel shop and have him torque it to the proper 330 ft-lbs.
