Exclamation Diff breather for water fording

Ok so I'm a little bit on the extreme side of what I do with my TH. Every scratch, nick, dent and gouge are badges of honor in my book. I once had a Pathfinder (94, first vehicle) and the day I got my license I was off finding trails and hitting it all hard. I do the same now with my TH but was wondering if there are other fanatics of off-roading out there that have some know how on putting breather tubes on their diff cause the last thing I want is to suck up mud and water and destroy my baby. Was reading this article and yeah it's Toyota but they were able to make some breathers for literally a few bucks, I plan on doing the same for my TH, anyone interested in seeing a DIY cause I don't mind doing the leg work, I'm a mechanic on and off the job, thanks all.

I am along the same line as you James. I do think it would take some exploratory surgery to see how they breath and how they function. Unfortunately, I don't have a rack/garage to do some major work on my end to figure this out. On top of that, most of my expensive tools and equipment are still stuck up in Alaska. I have enough Jeep knowledge and have broke more things than I care to admit that I may be able to lend a hand on possible design and/or limitations. As we have discussed before, you aren't too far away that some weekend wrenching wouldn't be that bad.

@Whsperz Awesome, glad to see someone else isn't afraid to put these Jeeps to the limit and possibly break some stuff! I too have been limited due to my townhouse community frowning upon vehicle work in the parking spots but we move into our new house with a 2 jeep garage early next month so Boom it is about to go down. Making a workbench and a place to hang my tools is going to help a lot with my poor man projects on my TH. If you have any ideas or anything you notice that could/should be changed let me know, and I'll do the same for you man, once I'm settled into my new place I'll def send you an invite if I get into some crazy project haha.

I would be surprised if, being a Jeep, we don't already have breathers that are fording friendly. Suppose I'll need to get the wifes TH up on the ramps and crawl under for a peek.

@Bill837 If you could take a look and let us know that would be greatly appreciated, I'll be more capable next month but as of now it's only what I can see from crawling under on the ground. Plus I've forded some pretty high waters (20" at the most) of standing water and nothing bad has happened yet, now I know that doesn't mean everything is going to go well from here on out but it wouldn't surprise me if they had a system in place. (Yet at the same time it would surprise me since they didn't even design the TH to easily be raised, tire sizes, and where is the aftermarket for TH, if it was even Close to the Wrangler aftermarket I'd be a happy man!) Thanks!

From my experience with both aviation acquisition, and the SRT-4 community getting pretty cozy with the SRT engineers, I think I have some insight into this. Designing for lift? Well, there's what you want to do, then there's what you can do. Corporate policy can be limiting. Engineering budgets can be limiting. Customer base can be limiting. And other times, you simply do a cost/benefit. How many owners might conceivably want to lift. How many of those would actually choose another vehicle were lifting not feasible. How much engineering/testing would it cost us to take an inherently unliftable suspension and change it up so it can be?

Got to spend some time chatting with an SRT engineer once and asked him a couple of our burning design questions. 1. Why in the **** did you give us a +220whp FWD car and a skinny ass six wheel for tires? A: There's a policy requirement that all Dodge vehicles be able to mount chains on the tires. Couldnt get a waiver. Did get a break in that they allowed for those to be cable chains, that's the only way he got even six inch wide wheels.

2. Skinny intercooler. Why not make it big enough to fit the physical space? A: Engineering requirement specifies that you cannot mount hard parts within 2 inches of crumple zone structure. You could, if you were willing to reconduct crash testing. Only cost a million or two. Given an expected production run of maybe 10K cars, not enough profit to make that happen.

Just got the Charger off the ramps last night so maybe I can do that this afternoon.

@Bill837 Appreciate the insight, I won't complain about the lift or tire sizes anymore, honestly I'm happy with how mine is, but I feel for the owners out there that want the same attention to aftermarket parts that the other off-road capable Jeeps get, and honestly now that you mention it, it Would make sense for there to already be a breather since by factory standards a TH should be able to ford 21" of water if I am quoting correctly, that would more than cover the diff! Thanks and looking forward to what you find.

That being said, I do have jack stands, some wood working tools, and a handful of automotive tools if you could use any of it or want an extra pair of hands in your way.
