"We've come this far so lets not ruin it by thinking !" Well...I can't help but think about this one. I also know that many of you guys know way more than me but I'm not convinced that over torquing is a good idea. Especially if it's nearly double what is called for. On one torque chart a 1 1/8'-7tpi , grade 5, bolt with waxed threads requires 397 ft lbs which attains a clamping pressure around 43,000 lbs. if the threads are clean and dry with no lubricant, it will take about 794 ft lbs to achieve the same clamping pressure. My point being that any lubricant of any kind on the threads significantly decreases "thread drag resistance"and can significantly increase the amount of clamping pressure to the point that the bolt is over-stretched. Also the threads of the bolt and nut may fail by shearing.
In this particular case, I'm not convinced that even 44,000 lbs of clamping pressure will stand up to a launch. Also cast iron, such as is the drums or disc's, has a very low shear force resistance. The axle is hardened steel and is capable of eating cast iron on any bad day.
I can't remember what VW says about oiling the threads but many car manufacturers say to use 10wt oil or they specify dry threads. What ever you do, NEVER use Never-Seize on anything except non critical fasteners in high rust possibility areas........Bruce
