The measurements were within tolerance to where it should have worked correctly. It didn't work.I returned it and still haven't heard back

I intsalled this and enjoyed it thoroughly for the first month then it just started to randomly release and slip kept getting worse and worse till the car wouldnt even move when in gear. Got a replacement and installed it and 4 months later im carless again because the locker failed... 10 out of 10 would not recommend unless ypu want to be rebuilding your rear every couple of months.
