Greetings..I have a 2014 Lariat, 5.0 6R80 trans, 145" WB 4wd. 154K miles..Since then the noises are virtually gone except for an About a week ago I started hearing noises from the right front on turns, sounded like a P/S pump low on fluid, but it has EPAS. Then the noises started on turns both left & right. Then I got the same noise while braking with the wheels straight. No hard steering, no codes. I checked what I could and lubed every bushing I could see, even the strut mounts , though they don't turn. My thought was maybe the rubber was dried out and getting noisy. Since then the noises are almost all gone except for a once in awhile noise which I can feel in the steering wheel. I'm not familiar with the EPAS System, but if it was going bad, wouldn't it be more constant ? Is there something more common to this model I should look at ?
Thanks !

 

Most things die intermittently, not just all at once. Did you lube the steering shaft joints? Any codes? EPAS tends to make a pretty high pitched squeal type of noise if it is really bad.

 

Thanks..No codes. Next I'll check the ball joints..

 

After reading and rereading the forums for ideas on the weird noises, I finally found out what the problem was..
The infernal IE system apparently has an intermittent loss of vacuum, so Sunday, I disconnected the vacuum line from the solenoid, capped it & plugged the line going to the IWE .
Drove it today & it's quiet as can be. Never though so many odd noises could come from this system.
