I got a 2011 ram 1500 4.7. my question is...the Haynes manual say steps 4 is to torque bolts 1-10 to 90 degrees but then on step 5 it says the same thing again. So 180 degrees?? That don't seem right. I feel like the bolts would snap! Can someone confirm this? Or should I just do the 90 degrees one time?
