Pop sound from front left when using 4a

After a week of driving I haven’t heard the abnormal noise. I’m calling this fixed.

Confirms my suspiciousness, mechanics these days are parts changers, sometimes they get lucky, sometimes not so lucky. Be very grateful that you're under warranty or this would of been a nightmare , so glad it is finally fixed and you have a near new truck at their expense and not yours. Happy trails!

FRF, I need your help! Sadly, my truck popping/clunk sound has come back. It sound exactly the same. Dealership is now telling me that it’s normal. I’ve contacted Ford customer care to see what can be done. I test drove another 2018 raptor in 4A and it didn’t make the noise my raptor is making.

Is it that clunk at about 7 seconds when you are turning? That sounds like an iwe popping into place.

 

[REX111]

Yes. It happens around 7sec.

When I first brought my truck the the dealership they said this was not a normal sound. Now after the did all the work they’re telling me that it’s normal. We test drove another gen 2 and it never made the noise. I don’t know why my truck would still make this noise after both iwe’s were replaced.

They don’t want to lose money on a follow up because they’ve spent their allotment from ford on the repair. As I understand it, Ford allocates so much $$ in time for labor as well as the parts for a given repair. Once you spend that time / $$, no more reimbursement. So, someone has to eat the cost.

I understand it, because Ford wants to encourage competency, OTOH, situations like this expose exactly the problem it creates. on a misdiagnosis, the stealership is pointing the finger at Ford and they are reciprocating.

That’s not a normal sound, and shouldn’t occur. Call Ford customer service and open a case with them. I run around in 4a routinely for years now and no, I do not have or hear that clunk and follow up chattering(?) sound.

It's probably not the iwe "parts", but a vacuum problem causing them to engage or disengage. Are you just starting the truck up with it in 2h and driving around or are you switching it to 4a or another mode just before you turn the corner? Why I ask the latter is because it can take a second or two to engage fully, etc.

Edit: can't remember but did they ever change that vacuum check valve which is near your vacuum booster for the iwe's? I know a few members had that solve a grinding problem.

It doesn’t grind. It just pops when turning low speed while applying power. On both videos truck was running maybe 4-5mins before driving. Truck was in 4A when started. Sound is totally random as when it happens. For example I have a 20 min drive to work and it won’t pop until I turn into the parking lot, but some times it will happen as I leave my driveway. I only use 4A with snow or rain just to have some added traction.
