ARB fail - Copper line design

[N4RNR]

How many people experience the copper line getting destroyed by the ring gear? Seems like the clearance is so limited, then add some vibration and it seems like the thing doesn't have a chance of lasting.

Once it's setup correctly, can one expect it to not be such an issue?

Had mine installed by a shop, drove it home, then within 15mins of driving with the diff lock it would no longer hold a seal, took it back, they opened it up and the copper line was destroyed. If it's that vulnerable, I am seriously questioning the design. My hope is that I won't have to worry about this thing once it's done correctly, but maybe all other ARB guys are always paranoid of the damn copper line as well? I tend to think if it was that common of a problem, no one would even be buying these things anymore.

Share your experiences so I can either have some faith in this locker or if it's a continual problem, it would be nice to know that as well.

You went to someone who did not install it properly.

ARB lockers are used in countries around the world. Not some new invention. I have no idea of numbers but there must be 100's of 1000's over the years. In Australia they are super popular and have been used for dozens of years.

Not saying they are infallible but your issue is clearly an install problem. I've had my copper line chewed by gears once after a re-gear....install problem! Had the ARB locker in my 4R since 2005.

The problem is getting the copper line under the lip of the housing before shoving the 3rd member into place. I did the same thing. Pushed the copper line into my gears and chewed it up. 2nd time after I fixed it I had my buddy maneuver it into place while I cleared the copper line and it's been fine since. As long as the clearance is there initially and it doesn't move a whole lot during install it should be fine for awhile and the worst case is the o-rings leaking.
