I've seen a few threads regarding the location and routing of the vent hoses for axles trans and tc. What I'm having a hard time finding is information about what type of hose they are, the size, and where to get them.
I have a 1993 xj sport, AW4, NP231. I have seen hoses for 97+ listed on eBay from salvage companies. Can I assume these are going to be the same given the similarity of the drive train on all cherokee models? If not does anyone know the diameter hose and hose wall type for 93? Even Mopar only has the breather tips for the end that attaches to the firewall...at least as far as I can tell. Local yards are picked out of these hoses apparently.

 

Just find some rubber tubing at NAPA or the like, or buy a roll from Amazon. It's not critical at all. It's just an air vent. If it fits, it's good.
