Question about a hose

[French_Toast]

My question has to do with the rubber hose hanging down over the differential, and ends near the bottom of the U-bolts... It was never hanging like that before and today I had a look underneath the truck and there it was. Now the day before, all that had gone on was I took the truck for a short run down the road, and tried 4 wheel drive for the first time I bought the truck, everything worked as it should have.. or so I had thought. Does anyone have an idea what that hose is for? I looked underneath and it seems to run under the engine and over the transmisson, but thats as far as I could see it before losing track. The first picture is taken from the front of the truck, second picture is from behind the drivers side wheel looking forward. Any help is appreciated. The trucks going to be put up on my neighbours hoist tomorrow, which is just across the street. So ill be able to get a better look then, just want to know if you guys have any thoughts or ideas on it also. Thanks.

Im almost positive its an axle breather tube. On your differential somewhere there is a little hole that the tube connnects to. Its routed all the way to your engine for no reason. Its just to keep out dust and crap from your axle. You can take it off and make your own you just gotta make sure its plugged up though.

Ok, thats no biggie. When its up on the hoist ill check on it, and re-attach it. Any ideas on what could of made it pop off? or does it just happen when it happens kinda deal?

Yeah it is rusty. Whoever had the truck before me didn't undercoat the underneath, so its in need of a good scraping/washdown/re-paint. Thats gonna be next summers project.

Thanks guys

Yeppers looks like a breather vent hose for a diff. They usually get snagged on something during an off road trip and pop off. Just push it back on and you will be fine.

Yeah, as soon as the truck is in the garage its going to be "repair and change" week (hopefully not weekS). Fix anything that needs fixing and change all fluids and filters, the guys who sold me the truck didn't know when it had been done last, so out with the old and in with the new.
