    Customers like the fit of the valve. They mention it fits perfectly for their 2000 Nissan Frontier rear axle vent, 2019 Frontier rear breather, and Euro Toyota Hilus. The valve has a bigger inside diameter and they can use 1/4 hose.

    5.0 out of 5 stars Fits onto 2001-2004 Tacoma rear differential breather
    Reviewed in the United States on July 19, 2023
    Verified Purchase
    Used this to thread into my 2001 Tacoma double-cab TRD rear differential breather hole on top of the differential. Originally there was just a breather valve threaded directly into it, which was perceptible to water infiltration. So I used this valve plus some silicone vacuum hosing to reroute a breather valve (Dorman brand) up behind the driver’s side taillight.

    5.0 out of 5 stars Fits 5th Gen 4Runner rear axle breather
    Reviewed in the United States on December 10, 2021
    Verified Purchase
    I always add one of these to my Toyota rear axles. The factory breather is ill-designed. After turning out the factory breather, I wrapped a little teflon tape around the threads and carefully turned this into my axle housing. Then attached some clear tubing with a small clamp up into my engine bay up to the firewall being careful not to pinch the tubing as I went and cable-tied it to the frame in a few spots. You can also use fuel line for added durability. Topped it off with a clamp-on small engine fuel filter and cable tied that right below the inner cowl. An easy project to protect your rear axle from sucking in water/blowing out your axle seals.
