I was changing oil on my 2000 Cherokee and noticed this black hose above the front u-joint
torn. It attaches to the top of the front transfer case.
Is it a vent hose? Can I just splice it back together?
Thanks for any help.

most likely its front axle vent just take it loose get a new pc

it's the front axle vent hose.

and seem like yoke seals leaking id replace it if youve been in any deep water id drain and refil front axle

Thanks guys for your reply.

I also got a dose of the death wobble on my 99 Cherokee yesterday.
Wow, that was interesting.
