How To Diagnose And Replace Ford 4wd Vacuum Lines Youtube This video shows how to diagnose and replace ford 4wd vacuum lines on my 2015 f150 xlt fx4 with 5.0l v8 engine. i walk through each step for trouble shooting. You can always try and fix it, lift the front end, start the truck, shift to 4wd, then try and spin the wheel to see if it locked. okay, thanks! for the vacuum line on my 06 i used 1 4" black drip (irrigation) tubing. (actually 3 32" if i remember correctly) it's uv resistant hell it sets in the sun all day when used for drip tubing.
2004 Ford F150 4x4 Vacuum Line Diagram Attach your vacuum gauge to the line after the solenoid and have someone switch to 4wd. the solenoid should apply about 14 15 psi for up to 60 seconds. then have them switch back to 2wd. the solenoid should apply about 7 psi for about 60 seconds. if neither of these happens then your solenoid is likely bad. I got all i needed to run new lines for less than $30 (my father in law owns the napa) and the stock ones for the dealership are about $60 70 or close to it. i bought about 20 ft of line just to make sure i had enough and i did have some extra. reply like. # 6. 03 29 2009, 01:16 pm. Start in the middle and work your way to the hubs following the old line and replacing it with the new. you will most likely find the old line very brittle. i bought the new vacuum line on e bay. hope this helps!! 2009 2014 ford f150 4wd hub vacuum line replacment hi i'm a new member here so hello to all my fellow ford owners, i'm posting. It ended up being the vacuum reservoir that sits just in front of the vac pump. plugged the line at the pump shuts off. plug the line after the reservoir pump runs all the time. i'm just suggesting you don't swap all the lines before going through the easy stuff. easy and cheap ($40 on line) fix.

Simply disconnect the vacuum line that comes directly from the pump and goes into your solenoid, and plug the vacuum pump line directly into the upstream vacuum line that's headed to your hubs. check my video for how to do this in detail. you will completely bypass the electronics of the 4wd system and apply direct vacuum to your hubs. To test the vaccum system, get a good vacuum pump with a guage on it, about $60 (or cheaper) at alot of parts stores. if when you try to shift into 4wd and it will not engage, most likely your solenoid is not working and releasing the vacuum to the actuators and engaging the hubs. replace the solenoid.
