    Default Jeep Differential Breather Tube Filters

    While at the Quadratec Tent Show, I saw these in a jeep. This is more of just a post with some pics in case anyone is looking build the same thing.

    The breather tube ran up through the tub and into these.

    That's just a tiny paper filter attached to the end of the tube correct?

    is it just a hollow cylinder between the tube and the filter?

    I don't know. The fuel cell only looked like it held a gallon or so f fuel, and there was no snorkel, so I am guessing it is set up for rock crawling. IIRC, the air filter actually sat inside the cab area and looked it was routed through the firewall.

    I just figured it would give people ideas if they were planning on trying to route their breather tubing higher.

    it was for the diffs breather hose?
    Not sure why you would really need a filter for those, maybe in a very sandy/dusty areas to help keep the fluid cleaner. Other than that I cant see a problem with the stock ones. I not sure the actual air intake on those is that much to begine with.

    In our area, we hit some pretty deep water, so should the dif cool fast, and water be sucked into the dif, it could be a bad thing. I think this may just help since it is above the tub.

    Fifthpro has an awesome write-up on fording and it talks about the quick cooling of the difs.

    It is common to extend the diff breathers into the cab and put a small K&N on the ends. It is also very common to adapt the Air intake to run into the heater box, under the cowl, and run a K&N in there for that. Yes all this is is a piece or tube to protect the hose with the filter attachment welded to the top.

    Rob told me about this company. They offer a direct mount and a remote mount dif air cleaner.

    Direct Mount:

    Direct Mount Diff Cleaner will mount to the manufactures existing "breather" hole. In most cases no tools are necessary.




    Remote Mount:

    Remote Mounted Diff Cleaner - Billet Aluminum - Cleaner body is machined from a solid piece billet 6061-T6 aluminum. Filter element is made of a self-cleaning polyproplene and keeps debris from entering the differential. Remote billet aluminum mounting bracket attaches high to your vehicle frame to keep water and debris out of your differential case. Includes mounting bracket, nickel plated water tight push fittings, filter, 4' poly hose, stainless steel/zinc plated mounting hardware and instructions.

    Please specify the color of poly hose you will require. Blue, red, yellow, black or green in the comment section at check out.

    I've seen those Purple Cranium breathers in action and they work very well. They are compact in size so you don't have something else bulky hanging on your frame/axle. I am actually planning on running these on my TJ if I get into Top Truck Challenge 2009.

    Those like pretty nice, I'll have to check them out. I've been wanting to extend my breather hoses for awhile now.
