What is this hose used for?

While I was trying to peek under to see the source of my messy power steering fluid leak. I noticed this hose was dangling and I pulled it out. It's other ends seems to be connected to front drive line black cover. Not sure what is the purpose of it and where should I hang it securely?
Also, is it normal to have so much power steering fluid leak? I just put lucas stop leak after this incident. Not very optimistic if it would help.

Yep thats your breather hose, as you drive and your gears rotate, it heats up the oil causing the oil inside the diff to contract and expand. Zorba is right, it should be up near the radiator

Thanks for responding I will tie it down near radiator properly. That is where I had it put temporarily but was not sure it's usage.

🤔As a general rule it's best to not start yanking on anything under a vehicle if you don't know what it does.
🤓 That Lucas stuff can do some amazing things if the seals aren't nicked or something.
🧐 It even claims to be 'ideal' for gearboxes and engine seal leaks. 🤷‍♂️ Anyone ever try it for those uses?

Thank you for your suggestions. I didn't pull it down it was dangling without screw so came out while I was inspecting power steering box.
I am awaiting the results of Lucas hope it fixes it.
Do you think it could take more than one bottle of 12 oz to see it's actual effect?

I had to ask the same a couple of months ago! but my hose was caught up in the steering the clip and screw was missing where it fits to the side of the radiator so I just zip tied mine up high and out of the way.
Exactly same with mine, the screws were missing in my case as well.

Some will say that Lucas sells snake oil. IDK but they did fix two different non-TJ automatic transmission shifting problems for me in the past.

Anyway since your TJ is early enough that it doesn't need ATF+4 transmission fluid in the power steering system I'd just use as much of the Lucas power steering stuff as I could fit in there and hope it works.


I meant tied up near top end of radiator.
Actually I think you do want to tie it down near the top end of radiator. Tying up is what I do the the garbage bag every week. 😜

I used about 16 oz in my tractor's hydraulic system that runs on around 2+ gallons and it was able to fix a small leak (seep) in the orbital motor for the steering wheel, a small drip in a loader lift cylinder and an aggressive drip in a bucket curl cylinder. And the steering has never felt better. So a 12 oz bottle should easily cure any power steering system leak that is able to be cured by an additive. If, after a 12 oz bottle, your steering still leaks then I would consider its seals well past needing to be replaced.
It took about a 1/2 hour for the steering motor, around an hour for the smaller hyd cylinder leak and under 2 hour to work on the larger cylinder leak. Remember though the stuff only circulates to the cylinders when they are actively being used, so I would think the 1/2 hour would be closer to the time needed for a power steering system if you are driving at the time. Really surprised how well it actually worked. I will report back if it ends up being a short term fix. I think it should be permanent on the two smaller leaks, but the bigger one is a big ask to hold sealed forever.

Standing a the front Jeep with the hood up looking towards the windshield it mounts near the top of the radiator on the right hand side the other ends mounts on a nipple on the front diff do not drive thru highwater without it or you will get water in the diff and possibly wreck your bearings

I am still looking at leaks it's day two. I have filled it to max allowed range as per dip stick. I have observed that it leaks more in daytime when sunny day warms up jeep.

I am not sure what right hand side you meant with a person looking down in the engine bay near coolant or driver looking from his driver seat towards right..
I may need to post a picture to confirm if I secured it correctly.
