Hi,

I recently change my f-150 FX4 2003 198,000 on odometer for one Lobo, in Mexico the F-150 call them "Lobo" King Ranch 2008 4x4 with 72,000 on odometer, no rust.

I change one ball joint and brake service, change oil's and spark plugs, coils, they have the factory one's.

When remove the caliper of front side passenger check that hose is broke.. what is that?

Thanks for the reply,

Sorry if my vocabulary is not perfect, i'm still learning and english is not my mother language

 

I'd like to say that is the wheel speed sensor for ABS, but no 100% sure.

 

It is your vacuum lines for your IWE. Without it your hub will be locked in like you are in 4WD.

 

Definitely looks like the vacuum line for the locking hubs. Does your 4x4 work? Most likely you'll be able to hear the vacuum leak when you engage 4x4. Se ve suave la troka. Felicidades!

 

Ok...just to clarify...which are you talking about? The thin black tube is a vacuum line, one is the brake line and the other I believe is the wheel speed sensor cord.

 

Both don't look right

 

I figured if the hub line was mucked up, he'd be feeling something. It looks broken though..so....who knows

 

Thats a good looking truck. Sorry, I don't have a clue on broken wire/hose. But somebody on here will know and help you out.

 

The first pic is IWE vacuum and vent line.. the second pic black zip tied wire is ABS sensor wire.
