I don't replace the strut bolts. The only bolt you'll rather replace is the axle center bolt. Maybe just don't fully torque to the specs the other bolts (bearing, strut)
The axle bolt gets grease on it because it sits inside the CV joint. I'd try cleaning a little the threads inside the axle, and careful when torquing as grease on threads can lower the torque enormously (and stretch snap the bolt) - if it keeps feeling easy to torque stop, the bolt is stretching
Remember to test the bearing by hand after removing the brakes and axle, before removing the bearing bolts. The bearing may be stuck solidly inside the hub, I strongly advise having a three arm puller
Read about the camber setting, I push the top of the spindle fully for fully positive camber
