The Lair

Well I have it narrowed down to my front locker somewhere. I double checked all connections but it’s still losing pressure somewhere. The compressor cycles on every 50 seconds for a split second to maintain pressure. The diff remained locked while the pressure dropped and cycled. I’m going to throw on the supplied arb fittings and hose and see if it does any better to see if it’s an internal leak or if it is the hose.

 

It’s got to be internal because the leak continued. Now the question is whether or not that’s actually an issue since the diff remains locked while the compressor is cycling.

 

Internal as in the locker inside the case is leaking?

That sounds like an ARB issue.

 

Could use get pressure in the lines and locker, unplug the compressor and see if the locker itself holds pressure?

 

I came up with a shade tree work around because I don’t want to mess with this anymore. Now, the threads on the locker are fucked up because apparently the crown performance lines supplied wrong adapters? Who knows. Now the adapter won’t snug up into the diff, it just spins.


My solution now is a new pressure switch. The current one kicks on at 75 psi and shuts off at 105. Arb says 85-105 should be supplied to the locker.

viair offers a 85-105 pressure switch, so I’m just going to install that. My compressor will cycle every so often when the front locker is engaged, but that’s not too frequent. I really don’t want to deal with this anymore because at this point, the solution would be to drop the front and send it to ecgs to have them take it apart, fix the bulkhead fitting and check for leaks.

 

Time for beer.

 

Yeah really. I feel like you right now with that radio.

 

I was digging around to see what it would take to replace my bulkhead fitting and it’s not feasible. It flares the end of the copper line down so I would need to replace the copper line in the locker too. That wouldn’t be something I’d want to do. For those curious.

I’m having issues with my front locker firing and think it’s the pressure switch. Mine look a little different than yours (I’ll get a pic soon), but I imagine they are the same basic thing. Would you sell your old one? Or have a link to the viair one?

 

This is what I ended up buying. I want to hang onto my old one but this one will hopefully work too.

Thank you, for some reason I thought they were $125 or something

 

Oh god no lol that would be terrible.

 

Seeing this plate bumper modified to be tucked up where mine's at makes me want to redo my bumper out of plate. This looks so clean.

 

You mean you haven't started?

 

I've already changed my mind within the past 47 seconds.

So I built my current bumper around my winch, the smittybilt XRC 9.5. I built this bumper to be tight as fuck. I'm replacing the winch with a warn and I have no idea if it'll fit in there. If it doesn't, then I'll build a new bumper that'll fit the winch*.

Clean as FAWK

 

So the crown lines are not good to use? Can you hear air leaking out of the breather hose when the locker is engaged that's usually the tell tale sign it's leaking. Matt from BK has been wheeling his JK for like 2-3 yrs now with a leaking front locker with no ill effects if that's any reassurance.

I didn't need any of that goop stuff on my solenoids or any of the fittings using the ARB lines no leaks. Only leak I had to contend with was the pressure switch.

 

The lines are great, the fittings they supply are not. i.e. that adapters to connect the line to the diff/solenoid. It's hard as shit to get them to seal. I'm going to check the breather hose later today and see if it's leaking internally and pressurizing the front diff.

If it is leaking internally, I wouldn't have known with the powertank setup since no compressor to cycle obviously. I'm kicking myself a little for trying to go against the grain and not just using the tried and true methods, but not a big deal. It's just a learning experience.

 

What tried and true methods? Just using the ARB lines? ARB also sells the braided lines probably with the correct fittings just the longest possible one is 3m iirc
