14 bolt vent issue

rpf500 · Jan 3, 2015

Replacing seals on my axle and thought I'd check the vent....not sure why I didn't in the past....maybe because its basically missing. This is best pic I can get. The truss goes right over the broken off vent nipple. So should I notch the truss and use the existing hole? Can I just pry this broken one out? I added speedi sleeves on spindles due to pitting so could be a combination of the 2 things that caused the leak.

If you look real close the shiny thing you see in the pic is a piece of wire I fished through the hole. Gives you an idea of how shitty the location is.

Can I drill a new hole somewhere and add a new one? If so can does it need to be in a specific area?

Put a vent on the tube like a dana axle. Just pull a shaft and run a magnet up the tube to catch the drill chips

Just curious why is your truss not welded to the diff any? Do you drive it on the road? Or for any long distance at speed?

I have driven it about 45mph around 10 miles one way. I prob won't drive on the road ever now that I have reds.

Another guy asked about the truss too. I didn't put it on so not sure why its welded everywhere but the diff. You think I should preheat it and weld it the rest of the way?

I thought about that just wasn't 100% sure if there was a reason not to do it that way. Figured I'd ask before I drilled a hole in the axle. Shafts are out already so that's actually an easy solution. Thanks for the reply

I would think it couldn't do anything but make the truss stronger and possibly keep the chunk from trying to twist? I ran axles with the vent capped of with no problems.

Welded up factory vent and added one to the tube. Thanks for the input.

I would also weld the tubes to the chunk!

Do I preheat, use nickel rod, or neither? Been reading about it and everybody says something different.

I've done a couple and always just preheated the chunk. Never used a nickel rod bc the chunk is cast steel, not cast iron.

Yea preheat wire brush 7018 or hardwire I've done both

You can't anchor the truss to your diff cover? Like a standard bouncer style link tabs bolted double sheer? Im sorry I can't see the pic for whatever reason
