Ok this is the second time in a month this has happened. The bolts that hold the ring gear to the rear diff keep backing themselves out! When it happend the first time a bolt shot through the diff cover. I pulled it apart and cleaned everything with brake cleaner. After it dried I put it back together with red locktite on all the ring gear bolts and a new cover. Now about a month later my rear end locked up. I got it unlocked but was still making noises. I pull it apart again, to find the same problem! A bolt had backed itself out and was lodged between the diff and the rear housing. And all the other bolts were loose, as in I took them out with my fingers with no effort. Why the hell do these bolts keep loosening up? Should I put JB weld on the threads this time since the loctite isnt working? Please give me some help if you had this or a similair problem, thanks.
