New Product Creeper Breather

[Chris Geiger]

Prevents dirt, debris and water from getting in to your axle through the stock axle housing breather. Expands and contracts to accommodate increase or decrease in housing pressure. Kit includes one housing fitting, clamp and bellows (as shown). Easy installation takes just a few minutes. No hoses to route. Fits all Toyota Pickup / 4Runner solid axle housings (front or rear). $19 each.

you guys know what I need! I've been lookin for a bellows for a breather for a while. I'll order through Trail-Gear.ca :thumbs:

School me a little.

I'm thinking that when the axle builds up pressure it would expand the bellow. There for I would need to install the bellow in the collapsed position. :confused: :confused:

[Chris Dunbar]

When installed in the free height position the breather will be able to expand and contract. If installed collapsed the axle will not be allowed to have a lower pressure differential than when installed.

I didn't know it was possable for the diff pressure to go lower then it is when at rest.

LIke I live in CenCal I go up to the hills to play in the snow, Up there the pressures are alot different. Like if put it on inflated, it would probably pop off when I got to 7000 ft mark...It all works on the temp. and alt. along with RIG temp. neat little gaggit :driving:

I am talking about atmosphere pressure differential as well as 3rd member pressure differential. Like when going from high altitude to low the breather will want to suck down.

Yes it is. Lets say you drive for an hour. By this point your diff oil is warm at around 100 to 150 degrees. The diff, housing, gears axles ext are all much warmer then the outside temp. Your cruising down the trail and the pressure inside and outside are exactly the same. Now you come up to a creek crossing and the water temp is only 50 degrees. Once your axle housing goes under water, the temp drops very quickly. As air temp inside the housing drops the pressure also drops creating a vacuum inside the housing. Without some way to manage pressure changes, the housing would suck water in through the vent.

I was looking at those on our ATV and wondered when someone would try it out on a truck.

[ALTER EGO]

What about driving down the road at Hi way speeds will the pressure build up and blow that thing off ???

What about higher elevation to low elevation driving ???

I live in 4 to 4500 Ft ele. and I drive to 500 ft ele. will it collapse that much ????

The only time I have seen a problem is when the seals failed on an ARB in the buggy. The pressure from the blown seals in the ARB filled the housing with pressurized air and the breather ripped open from the pressure. Other than that you won't have any problems. These have been used with no troubles at elevations way above 10,000 ft and on daily drivers.

Cool thanks Chris I think Im gonna get with Dave at Daves Off Road and get me some of these

I'd like to try one of those . . .

Right now I'm running the typcial extended breather line but I noticed when I was changing the gear oil that it wasn't comming out smooth. It was comming out in gulps as if air wasn't able to get in from the breather. . .

Out of curiousity I pulled the breather off the hose and discovered that I could blow air through it, but I couldn't suck air through it. So I'm not convinced that those standard Toyota breathers work very well. . . Am I missing something there? . . .

My only concern with the Creeper Breather is whether the size of that little expandable tube could limit the amount of air volume that is allowed to go in or out of the diff. For example, if the vaccuum in the diff is strong enough (like in snow or river crossings), could the diff suck all the air out of that tube and still need more? Or, on the other hand, if the pressure is great enough (like highway driving), could the diff want to push out more air than that tube can hold? . . . . It seems like the single advantage of the stock toyota breather is that it allows unlimited release of air (I just don't know how it allows air back in).

mmmmmmmmmm nice looking piece of kit.:D
Simple yet functional.

However question:
I realise that this is not designed with racing in mind, but what sort of speeds can you enter water/mud at before the bellows will get ripped off of the diff housing.


Also if you drive through windscreen deep water does the water pressure cause any issues?

[Trail-Gear]

I do not know at what force the breather would get ripped off of the axle with a high speed water crossing, but I can tell you that it has a full inch of engagement onto the brass barbed fitting. The fit is tight already, but we still felt better selling it with the clamp band. This unit has been used in desert racing and rock crawling for several years and works great.

cheers for the reply. I was looking at using them, but also putting a protector plate in front of them.:cool:
