Finally got around to installing the ARB Differential Breather Kit I have had on my work bench for months. As well as the standard breather kit I also ordered their kit with additional tubing and fittings to vent the transfer case and transmission along with the diffs.
I looked at a lot of options on where to place the manifold and filter, finally decided on the driver side of the engine compartment toward the firewall.
This area normally stays dry even when hitting water pretty fast. The filter itself is splash proof so even if water does spray up in this area it won't be a problem. If I have standing water up to this point I have bigger problems to worry about than if water is getting into the breather lines.
Top view of the manifold where you can see the connections a little better. Note that one of the fitting is currently replaced with a plug. Didn't have time to get to the transmission vent line which is on the top of the transmission. Will go back for that one hopefully later this week.
Ran all new vent tubing.
I was concerned about snapping the vent tube connector off the front diff because there is no way to get a wrench on it to remove it that I could tell so I left factory connector and used a hose clamp on it.
Was able to replace the factory fitting on the transfer case with the ARB push fitting.
I have run the new tubing back to the rear diff but capped it there. The rear diff has a larger hose barb on it and again like the front diff it was hard to see how to get a wrench on it to remove the factory fitting. When I drop the axle hopefully in the next few weeks to do the spring over it will be easier to change out the fitting so will do it then. Will plan on adding more detail when I get it done.
