Hello everybody!!

I hope someone here can help me, I have a 1980 4x4 and I was on a mission to replace my 20 year old shocks when the trouble began. As I was taking off one of the wheels, I realized the tire shop cross threaded two lugnuts, as they snapped right off, so I began the process of replacing the wheel studs. As you know you have to remove the hub clear to the rotor. Anyway, as I am putting everything back on, I get to the bolts that connect the hub to the rotor and was wondering what the torque settings are. Well, my Haynes manuel offered no help, so I call my mechanic friend. He tells me anything about or over 80 lbs. is good, as long as they are all the same. So I go with 80 and as I get to the third bolt, I notice I just split the lock washer apart. So I go to the next one and it feels like the others did just before the wrench gave at 80 lbs but this time, the bolt snapped off. So now the count is three broken bolts and a truck that I still dont trust to drive.

My question is, what is a good torque measurement for the hub to rotor bolts. There are six of them and they have lock washers. Also, the torque measurements for the outer hub (where you turn it from free to lock) could be helpful as well. That is if the local junk yard has the parts to help me out.

I am nervous that if one of the bolts broke, the others may be weakend as well.

Any help would be super helpful!!!

80 ft/lbs or 80 in/lbs? 80 ft/lbs sound like a lot of damn torque to me!
