Hi guys new here in search of suggestions, i have a 2005 ford f 150 5.4 triton 4wd. I got the dreaded grinding noise under the driver side dash,so after doing my research i replaced driver side front bearings and both actuators, solenoid, vacuum lines and transfer case motor. And still get the noise at around 60 mph. This is my first 4x4 and im learning as i go and the previous owner had a raptor gen 2 coil over fox lift on it. Any suggestions would be appreciated

 

Never heard of that
