Re: Dana 34: D44 hubs & brakes on D30 Knuckle

To get all the strength you can, a socket head cap screw is stronger (by about 1.13 times) than a grade 8 bolt, you might want to throw those on there for a little added factor of safety.
Two things I think negate that. Since he turned the spindle down to such a good fit, the knuckle/backing plate help support it much better. Also, the stock hub bolts are Class 12.9 which are slightly stronger then Gr8 too.

Im just thinking out load too.
