Mine have acted up on occasion and sometimes I had to repeat the pull forward then reverse a few times. Other times I've jammed the brake or rocked the steering wheel from side to side while rolling backwards. They've always unlocked at some point. At some point I should pull them apart and clean and regrease everything...but I just haven't had the time, and when I remember I need to do that is usually right after I need 4wd <img src="/forums/images/graemlins/notooth.gif" alt="" />
