I have an 87 1/2ton 4x4 Silverado and the vent tube from the rear end that attaches to the rubber hose on the bottom of the bed has rotted off. I can't really recognize what the fitting into the housing is supposed to look like. I cleaned it out with a wire and it's now clear but there isn't anything sticking up to attach a new rubber hose to. I never off road and wondering how important it is to reattach a new vent hose?

VERY IMPORTANT!. There should be just a barb nipple sticking up from the diff that the hose would slip over.

Thanks roundline. The barb is rotted off. Can I still get this part from a dealer or do you have a suggestion. It's difficult to see how it even comes out as it appears round. Any pics of what it is supposed to look like or a link to the part??

Get a easy-out and remove whats left of it. If you can get it out and the threads are still good, find a threaded barbed hose fitting that will fit. Otherwise drill it out and tap it to fit a new one. If you do drill and tap, make sure you remove your diff cover and catch all the shavings with a rag so they're not floatin around in your gear lube!

Thanks, Gutter Runner. I'll try the easy out first. After googling for awhile I finally saw some breather kits and seen what the fitting is. Just hard to recognize when there's nothing much left to look at......haha.

Let us know how you do

Finally got-r-done. After a can of wd40 and some heat I was able to remove the rotted barb fitting with vice grips. Really strange that the fitting seemed to be some sort of self tapping deal with few threads. I couldn't find a brass or nylon barb that would fit so I just made my own and it threaded in well enough to fit tight. For some assurance I smeared some JD weld around it to prevent any moister leaks and clamped on a new hose and attached to the bottom of the bed. Thanks for the tips all.
