camber bolts are scary dangerous too. they can back themselves out even with the tabs, i had mine do that. slot the bolt hole on the part that attaches teh strut body to the hub. thats what my jic's had, gave you the ability to run -5 in the rear (which it did when my frakking camberbolt loosened itself)
The reason your camber bolt probably loosened itself, is because it was used in that slotted hole... A camber bolt is a bolt thats one size smaller (thinner) than the original/oem bolt with an offcentered bulge on it that is designed to fit snuggly in the original oem bolt hole. If you use the bolt in a slotted hole, it won't fit properly and will not do its job adequately.
