Great video. You mentioned you thought it was the lines because you changed the actuators…is this because you continued to hear grinding after the new actuators were installed.
@roberstreett5766, yes I continued to hear and feel a whine at the front end under the drivers feet. I put my go pro under the truck and found out the front axel and one cv was still spinning. Since I replaced the actuators already I thought it could be the vacuum line so I vacuum tested them. Turns out it was a cracked line but also one of the new actuators failed and needed to be replaced.
I actually found your first video where you tested the lines as well. What was different this time? Just curious because I replaced my hub and actuators and wondering if I should replace the vacuum lines as well.
@robertstreett5766, the lines tested out fine previously but later on showed vacuum loss. I'm guessing it was a hairline crack somewhere in the line that didn't show its self previously. If you replaced your actuators and think you solved your problem they could be fine but it's good to vacuum test them to verify. It's also good to test the actuators that you installed. I had a new one fail on me right away. Here's my full video for diagnosing the 4WD system. th-cam.com/video/fa0vKrLtqbA/w-d-xo.html
@Dyna2023, I just plug them in and make sure to seat the rubber line all the way down. I wouldn't use silicone incase you need to take the connection apart you'll just damage the line.

It looks like it's a similar process and concept but I'm sure the routing is a little different.

Great video ! I am really curious how many hours it took you to do this. I was just quoted by my local Ford Dealer $1,138 they broke it down like this $138.00 for parts x 50 hrs labor. Of course I suspected they're just hi balling me because they don't want to do it, but I don't know. Would be interested to hear your thoughts. This video will be a great help because it looks like I will be doing it myself.
@@jjoyceman thank you! It's not that hard of a job, only a few tight spots. I spent a couple hours trouble shooting and replaced the vacuum lines in under 2 hours once I had the parts.
Yes! It should apply to all engine types as long as its 4WD from 2015 to 2020. Same concept applies to other years but the part numbers may be different.

Holy cow was this easy. 70000 thumbs up to you man. Saved me loads of time
Thank you for the comment! It's really not bad to trouble shoot, it helps to have a vacuum pump.
@@jacobsupgradesI’d imagine. I had raccoons chew my lines though! I knew they weren’t holding pressure! lol. Thank you again!
@@codydoerzbacher7864 lol well that's much easier to diagnose. Those dang critters. I'll bet you have a live trap out by your truck now lol.
My F-150 has had the dreaded grinding rattle. Wasn’t sure how difficult this is but it seems pretty straightforward.
Thanks!
This is much easier than replacing the IWE's! Glad to help.

Do you just plug in these lines, or use silicon or some sealer to make sure they don't leak at connection?
@Dyna2023, I just plug them in and make sure to seat the rubber line all the way down. I wouldn't use silicone incase you need to take the connection apart you'll just damage the line.
What part numbers and where did you order them from ??

Would this also apply to a 2017 f350, or would it be completely different?

@@jacobsupgrades That's about what I figured a few hours should do it. Well I'll find out. Thanks for the video it's going to help a lot !
Would this be the same for the 2016 f150 xlt 3.5 eco boost?
Yes! It should apply to all engine types as long as its 4WD from 2015 to 2020. Same concept applies to other years but the part numbers may be different.
