I just installed a Quik lock a.k.a. Lock right in the rear of CJ5. The rear end is a amc model 20. After the install the rear is deffinately locked, but its supposed to unlock when going around corners. It will not come unlocked now, I know this because my turning radius is gone. What did I do wrong on the install?? I could have bought a spool if I wanted this. I thought I was careful with instructions. Any ideas?
