I have been running ARB's for over seven years. The only problems I have had are, I had a solenoid go south, one set of O-rings due to installer, Wore the pump becaused I used it for OBA, cost thirty dollars for a complete rebuild kit. And I broke the ring gear flange off the housing due to the ring gear bolts coming loose after seven years of bashing, ARB completely rebuilt it for two hundred and fifty dollars. I have ran them in the snow, deep water crossing, rocks, and the desert with out a failure. Even the blue line for the rear one is the same blue line I installed seven years ago.
I have seen more failures with the e-lockers then I have with ARB,s and in my opinion an e-locker does not lock/un-lock as fast as an ARB
