ARB stuck

87 CJ, ARB locker, rear is stuck locked. Pressure is off, I even applied a vacuum to try to unlock it. Anyone experienced this?


The compressor is going too, blew a 20A fuse. I may just yank the whole system out. Thankfully, it's not mine, I have 2 Powr-Loks in my Jeepster. Trouble free.


From what I know about ARBs, besides the plastic lines failing the most common problem is diaphragm failure. However, I think in that case it won't engage, rather than sticking. Only way to tell is to pull the carrier and disassemble.

I have an ARB in the front D44 on my YJ, it's used infrequently so I'm hoping it won;t fail any too soon. The Detroit in the rear is a handful on the street, but superb on the trails.
