ARP bolts. Dunno the pitch but whatever that isAre you running 7/16-20 or 7/16-28 bolts?
There 7/16- 20 boltsAre you running 7/16-20 or 7/16-28 bolts?
A bolt is under twisting load as well as tensile load. Whereas, a stud is under only tensile load and also less apt to come loose. If you don’t torque those bolts to the max rating with a torque wrench, you’ve wasted your time.one thing to note is that the clamping force is much tighter with the bigger hardware. I torqued down on it pretty hard. didn't use a TQ wrench and just snugged the crap out of them with a ratchet.
Toyota spec is 26lbft on the hub studs. Front Range Off-road spec’s 30lbft for the ARP studs they sell.per ARP's website, 7/16 bolts should be 70 Ft-lb max and 8mm should be 24 Ft-lbs max.
proper torque is important to prestretch the bolt sightly to ensure your flange and hub body dont seperate from each other and allow the bolt to go from a shear stress to a bending stress situation as the shear rating is alot higher than the bending/tensile rating.
yeah i was only looking at the generic bolt torque to show the drastic difference between 7/16 and 8mm.Toyota spec is 26lbft on the hub studs. Front Range Off-road spec’s 30lbft for the ARP studs they sell.
I would do this mod if I had broken hub studs in the past but there is no consistent data telling me that I need to run larger hardware. I think that a 10mm stud would out perform a 7/16 bolt.I would be reluctant to tighten those bolts to 70 lbft
The ARP bolts are fine, but the new larger holes are now closer to the edge of the hub
Racelines clear with no modsDo your wheels still clear the shoulder of the bolts? I know that has been an issue for others in the past.
This is what I was thinking 40 or 45 ft lbsI was tightening mine to 70 for a years now i just do 40ft lbs. i was starting to deform the Aisin hub bodies and axle flanges.
I did a pre torque to about 60lbs to get a pre-stretchThis is what I was thinking 40 or 45 ft lbs

I loosened everything yesterday when I installed the pins and TQd it at 45lbs. prior to reading Cmatt's post.
I might loosen it again today and go down to 40lbs.
