I have a zip in my front and rear, I have used the lockers maybe on a dozen trail rides for individual obstacles. My rear locker has developed a leak in the differential where air comes out of the breather. Because of the rear leak neither front or rear will work which I found out on the trail. I pulled the diff cover and did not see any glaring problem so I assume it's in the locker itself. Anyone have a similar issue?

I swapped my Yukon locker connections with ARB. Mine just wouldn't hold pressure. The ARB are far better. I don't care for ARB, but they make much better product.

I swore arb used odd sized air fittings where zips use standard 1/4 if i recall. I watched a thing the other day comparing yukons zip to arb and yukons grizzly to detroit and yukon won both in terms of strength and warranty. I swear they mentioned air fittings as a down side on the arb.

I'm not comparing strength or operation. Straight up air fittings. The Yukon blow. Had a shop do my rear gears. They couldn't get the locker to hold pressure. Swapped in an ARB fitting and no issues. I dealt with the front. Same issue. Ordered new Yukon fittings. Same BS. Had a spare ARB from the shop and boom, worked like a champ. Just looking at them, the ARB are a better design. I won't blow up a locker, but I'm apparently the first person to get a locker replaced because they totally jacked up machining the splines. I want to like Yukon, but I've had nothing but issues.

So it swapped easily it was the same size fitting? Yukon also takes less psi to lock (or unlock) typically

I was under the impression that the line size for ARB was different. That said, I have no issues with the ARB fittings and Yukon line.
