hi all...

i'm trying to find the right hose that I need to check and or replace ?

2004 250

thx

 

Here is a single post to your question. Can you give a little more information?

 

My 4x4 on the fly won't engage and I was told it could be the vacuum hoses and I was going to check them..

thanks,

 

I do not have ESOF but past history on the subject it is probably the hub seals leaking. Do you notice the pump running constantly?

 

hello... No I haven't noticed anything on the pump... but i'm not sure where the pump is...

 

Passenger side under the hood. Behind the battery. The vac pump has three small tubes going to it. The valve next to the pump is what works the 4x4

 

thanks... I will take a look and listen first thing tomorrow..

good day,

I found the pump and no its not running all the time.

Is there something else I need to be looking for? its there a way to test the pump?

thanks,

Brook

 

The pump does not run continuously if everything works and no leaks. You would notice your defrost to floor not working if you had no vacuum. I still vote for the front hubs. Have you manually locked the hubs to make sure the transfer case is engaging?

 

Yes, I have been able to manually lock the front hubs.

So what is your recommendation at this point?

Brook

 

Check the seals on your front hubs or lock them manually if needed.

 

great.. thanks...

Will start looking into it.. or might just manually lock them.. :_)

will see

 

ARe the front hub seals something that the average joe can change?

or is it something that I need to have done?

Thanks,

BRook

Any youtube videos?
