Spindle Steering arm torque spec

Not sure if this is what you are requesting, but I'm attaching a couple of torque spec sheets that I have from my Pantera collection

If you'r using the original 10mm bolts use these values:

30 to 35 ftlbs. for the 8.8 grade bolts

40 to 45 ftlbs, for the 10.9 grade bolts

Thanks Guys! Using 10.9 upgrade bolts with new nylon lock nuts, and the one no- hex original bolt. I noticed my driver side 2 new bolts had come loose after recent inspection and not sure why. I did a complete rebuilt last year and know I torqued them to at least 40 and the passenger side was ok. That's why I asked about the blue lock-tite as well. I don't think it can hurt.

The OEM bolts loosen because they are poor quality and they stretch. The best solution is to enlarge the holes in the spindle and steering arm and use 7/16" aircraft bolts. The second best solution is to use grade 12.9 OEM sized bolts. 

Thanks David.  Funny that only my new nuts were loose though, and only on the drivers side. After thinking about that, and looking at everything I realized my i( I think) my issue is I used flanged nuts, and the bolt threads do not extend past the nut, just flush. The threads are not engaged enough on the nylon lock, so they come loose.  I believe the original nuts did not use a washer? I'm going to replace them with new nuts that are not flanged & torque them to 45. Maybe use some blue loctite as well.

The tip I mentioned earlier was given to me by Dennis Quella. He installs the 7/16" AN bolts as a routine part of any suspension work.

A fellow owner I know just recently performed the larger bolt modification on his spindles. He told me drilling the spindles was far from being an easy task.

Guys,

Duly noted on drilling them out. I don't plan on doing that at this time, although I'm positive that would be a sure fix. Going with new non-flanged nuts & blue loctite for now.  I like this Wilwood setup though!
