Struts coming loose?

I don't, but if you are using new bolts, they may not be threaded far enough to actually be tight when you tighten the chit out of them. Back when I was an alignment guy, I installed hardened washers one on each end, under the head and under the nut; so that they had enough thread to actually clamp.
I found out the hard way, thankfully on my own car. Backing off the alignment rack and grabbing some brake, I heard an awful noise. When I got out and looked, there was my wheel assembly pointing off into the wild blue yonder, as they say.
