Hey guys, looking for some guidance here as I am out of ideas at this point. For the last 2 years, my truck (2014 F150 S'Crew 5.0L) has made an awful popping noise in the front end when i fully turn the steering wheel, whether it be left or right and slowly drive forward or in reverse. This week, i finally took it into a mechanic friend of mine and he has since replaced the upper control arm, lower ball joint, sway bar end links and the sway bar bushings. He also installed a set of the Bilstein 5100 shocks in my truck (front and rears). I just picked it up and it is still making this awful noise but the weird part is that it doesn't happen every single time i fully turn the steering wheel. I also noticed that i can hear a little bit of creaking / popping when i turn the steering wheel just sitting still in park.

I am aware that there are quite a few threads on this same subject but most of them never come to a conclusion or they say to replace parts that i have already now replaced. Based on the information above, does anyone have ANY idea as to what might be causing this? It's driving me insane!

Thanks!

 

Lub' the U-joints of the steering shaft. *I use 80W-90 or 75W-140 gear lub'.
.

 

Where are those located?

 

On the steering shaft.............

 

Ok, i greased the U-joints and still getting the popping. Where else should i be looking?

 

You may be looking at taking it to a Ford dealer for a thorough front end inspection. You have electric power steering, things are a bit different than they used to be.
