I had a hard time finding this replacement after my previous one rotted.
This interesting breather valve has a dual purpose to allow pressure out of the rear and holds down the distribution block for the rear break lines.

I bough it from here and its the perfect fit.

QU20254 Axle Vent Fitting for Ford Dana 80 Rear Axles

Attachment 294016

Fits my 1995 F150 4x4 with the 8.8 rear

I figured I would post this to make some others lives a bit easier when trying to find this part.

 

Thanks. This is good to know stuff. I needed one for my fathers 2002 F-250 and just used one out of one of my spare 8.8's because none of the auto parts store knew where to get one and the dealer didn't list it either.

 

Yea it was a pain in the *** to find and I just took a gamble on it because it looked like it was right.

I checked all the ford parts dealer and they could not get a part# either.

I hope this will help others find this a bit easier.

 

That is for axle vent hose...
Do you know what the part name or part number that connects to the end of the vent hose? i found this part number 4A001 but do not know if it is a clip or filter.

 

Sorry I dont know the part number for that plastic filter thing.
I do know that a lot of people will use a small fuel filter instead for that.



you can get something like that here
you just have to make sure that you run it up and then point it downward just like in the photo.

 

Thanks for the information!
This way i save time and money

 

I was super happy to see your post as I need one of these too. I went to the site right away, hey, for $14 I'll order two. Crushed me after that....told me he wanted $36 to ship them. Didn't get my business.

Oh well, guess the search continues!
