Axle Breather

When it comes to axle vents do all of you just extend all of them or has anyone used the creeper breather kit.

interesting concept... :brows:

Mini check valve........$2.00

I like going the cheaper route. Any more info on those?

Have you used these?

Why a check valve? Seems like it could get clogged up pretty quickly? I use these on the axles and tranny. Press fit into the existing holes and straight through with a removable cap for cleaning.

They are selling the $21 'bellows' as a gimmick in my opinion. The idea that water will not enter the axle or trans housing.

 

There are three on your MJ.......$63........for man who has everything.

 

 

A check valve on the line side of the breather will insure no water will inter while you traverse the depths of Deep Creek.

Ah okay, makes sense. That ain't going to happen for me though, at least intentionally.  :yes:

your best insurance is a brass nipple, and some hose and run it up into the engine bay. The breather needs to breath in both directions as the diff gets hot the air and oil inside expand. When you cross a creek you create a rapid cooling situation that can actually suck water in through the seals if the diff is unable to breathe properly.

 

FYI - those are just stock Kawasaki ATV diff bellows for twice the price. If I was going to use those I'd still run a line up the engine bay ... but a double coil on the end of the hose, or the breather caps hornbrod posted work better and cheaper IMO.

if they were designed for a tiny atv, I wonder if they allow for enough air movement on a Jeep axle

[Rockfrog]

I've heard of a few trying them but thats as far as its ever gone. Down on the axle ... at least around here ... they'd get ripped off. My concern would be the same ... will they allow enough air movement ... drive axles get surprisingly hot.

Definitely like those for an option better. Are you using fuel rated hose?
