So I have a loss pf pressure in my line and tried to determine the issue.

Here is what I found.

This portion of the line connected to nowhere. I could not determine where it goes to so I just Ductaped it off to try and keep some pressure in the line.

Under hard acceleration I can hear grinding from my driver side wheel well. This is most likely my 4x4 hub wanting to engage correct?

This pic was taken on the driver side.

Need some help!!

Thanks!!

 

Very likely the actuators are making the grinding noise. Not too hard to trouble shoot and fix...

The first link is very helpful. The second has a few pictures.

 

I have this same problem.

 

Not unusual. After the Autospring lift I had the problem. It's a given both wheels need to be hooked up..start there. BTW, I'm not happy with Ford with how Sh***y the lines are in the first place...why'd they stop there? They should of used McDonald's straws..

 

That thread helped. Never thought it would be that easy to replace an actuator. I wish I could of found out sooner and saved $700 last year when I had this issue. But last time I had it, it was really bad and constant grinding. Turned out a whole section of my vacuum line was missing.

All I need to find now is where that little hose plugs into.

 

I've noticed a lot of posts saying they had this problem AFTER they installed the leveling kit. Mine started after I did mine. Coincidence? I'm thinking of taking mine off!
