Avoid Costly Repairs: F150 Grinding Noise Solved. 4wd actuator

[@ozzstars_cars]

Two vids in one weekend! You're on a roll Will!

[@robinsonsauto]

I’m trying lol

[@shawnmrfixitlee6478]

We had a Dodge Dakota start grinding .. It was only part engaging , Simple to swap out but it was on a boat ramp .. Great share Will

[@robinsonsauto]

Sometimes the work environment can make all the difference. On a boat ramp sure don’t sound ideal

[@spelunkerd]

What an interesting design. I don't know if I like the way it locks axles if the system fails. Most 4WD systems default to 2WD, which in an old vehicle may be easy to ignore. Also how do you tow it from the rear? The axles will be locked and wheels will chatter down the road.

[@robinsonsauto]

Very good question and concern, I honestly don’t know. I feel the same as you do. I have had chatter concerns as well due to a failure in the system. These actuators can get water logged as well and cause partial engagement. That’s why I always check if they engage and disengage by hand.

Great info! Thanks for sharing!

Mine has full vacuum at the hubs 23+, holds vacuum for an hour. No grinding with module unplugged, but grinding every time after driving for a few miles. Replaced check valve and module.

[@joeyl1742]

Could a four-wheel-drive solenoid cause the same symptoms. I have a 2017 and I replaced the check valve and I have vacuum tested all vacuum lines going down to IWEs and have individually vacuum tested each. Even after replacing the check valve I still have intermittent grinding. Which leads me to believe the solenoid is bad. Also, I hooked the vacuum gauge up while I was driving and occasionally the vacuum would drop low and it would grind. Only happened sometimes.

[@JohnR9965]

How do you learn all this stuff. Lol. Great explanation!!

[@robinsonsauto]

It’s sink or swim most times lol I wing it more often than not, after looking at the system and how it functions. TSB’s will most times point me in a good direction. I’m certain there is other methods out there for testing this. Sometimes I need to actually see it hands on. This video could have been much deeper, prior to recording this I changed the left front actuator because it would leak when rotating the wheel. But I was already passed that and thought hmm I should share this test.

[@JohnR9965]

@@robinsonsautosounds good. Keep ‘em coming. Your good at explaining this stuff.

[@jacobmiller2857]

Can I drive with this issue?

[@the_stixXx]

Thanks for sharing. I have a 2009. Its not in the same location and I'm trying to find it, do you know where it is located on the 2009?

[@robinsonsauto]

I'm glad you found the video helpful! The location can vary slightly based on the model year, but it's usually not too far off. Have you followed the hose from point A to point B?

[@the_stixXx]

@@robinsonsauto no I have not. I was going to and then I came across a video that showed my year truck and it appears like it's near the front right. I will have to follow the line from that point to see if that is actually it. Thanks for replying.

[@theyetty9969]

just took mine into the dealership for repair, theyre saying its a grand or so to replace this

[@dillenchaniceursuabelt9845]

Where are you located

[@sancheezyfilms6134]

I changed the check valve and I’m still hearing noises what else can it be?

[@dude8223]

Heat sheild weld breaks, will cause rattle. If so, put a hose clanp on it.

[@sfcjerryharris1]

I changed the check valve and solenoid and my grinding went away

[@petar443]

Mean machines these Fords. And theres plenty of parts available ,even for 20 years old model. New parts aftermarket parts junkyard parts everything.

[@robinsonsauto]

I own one for a reason 😀☝️

[@fatsquirrel2554]
