I leave the front spring eyelet slightly loose, tighten the u-bolt to spec lower the weight of the car on the springs and finally tighten the front spring bolt.
Make sure to re-torque the u-bolts a couple times after the first few miles and again after about 50 & 100 miles. I also always use anti-seize sparingly on the u-bolts, nuts and thick washers; and slather synthetic disc brake grease on all the bushings including the shock bushings. It won't attack rubber or plastic and contains lots of good slippery stuff that is very resistant to washout. It also reduces sticktion and squeaks.
