Here’s an anecdote that is relevant to our discussion of bypass hoses. Around 2014, I had this t-case rebuilt at a well known shop in CA near where I grew up. All was well cruising around in 2wd and I headed off to school in AZ. About a month after the rebuild was done, I wanted to go explore a 4wd area near Wikenburg, AZ with my girlfriend. We drive out to the trailhead and I shift into 4Lo to get past the gatekeeper obstacle, some piled up boulders. Start creeping forward and as I’m going toward these boulders, I hear a sound like liquid falling on sand nearby. I look in my side mirror and see a trail of liquid in the sand behind me. F@CK! I stop, hop out and see that oil is pouring out of my t-case! It was leaking profusely from where the 2/4 shift fork exits the case. The area was remote and I had no way to fix it there, so I hop back in and tell my girl we’re goin home. Then I drove the truck home ~60mi and call a local cruiser shop that had good reviews to get it fixed. After the repair, the shop told me that shifter seal was installed backwards and had failed. (I don’t really see how that’s possible after rebuilding it, it very clearly goes in one way.) To my surprise, the case survived and continued to serve until I destroyed the output gear during my rebuild 🤦♂️… Long story short, if I had a bypass hose installed I could have lost my t-case and tranny. Also, these trucks are TOUGH.
