Lucky I caught this again, the rear bolt in the lower control arm was about to fall out. This happened before and I put locktite blue on it and torqued it to 55'# but it came loose again. While under there I checked the rest of them and the drivers side rear was loose 3/4 turn. It has been years and thousands of miles since last time I checked them, but WTF? I think it may be greasy inside the female threads so I sprayed it with carb cleaner and ran the bolt through a few times. Then I used the blue locktite and put it in and out 3 times with more locktite on each time. I have heard of this happening to others long ago on another group. The bolts had lockwashers, maybe I should try some double star lockwashers? Or should I clean it better/again and use red locktight?
