I heard that you shouldn't wade into water deeper than your hubs unless you extended your differential vent tubes. Since I have a mostly stock '95 YJ Rio Grande, I figured I'd probably want to extend them in case I ever decide to go swimming. After looking around my pumpkins I noticed that there was already a hose coming out from them. Since it's stock and I've never seen a differential vent host, I'm wondering if this is an already extended hose or something else.
Here are some pictures:
The hose comes out of the top right side of the front diff pumpkin and snakes around to near the radiator on the drivers side. It's the gray/white looking cap in the second picture (a little hard to recognize).
Is this standard for the '95 Rio Grande's or did the previous owner put them in? There is a similar one in the rear but I couldn't quite figure out where it went. Thanks.
