Good day, been having a few issues with my 2011 F150 ecoboost. started a few weeks ago, when i would turn right i would get a slight grinding noise in the front end. i check the brakes and bearings to see and all looks good. it only does it turning right at a low speed.

but now the last 2 days driving at normal speed, there is a whirling sound and a little grinding also. it sounds like the front axle is trying to engage. It does not do it in 4X4. Any help would be great. thank you in advance.

Your front hubs are possibly losing vacuum. I had the same issue. They replaced both IWE acactuators. One of the tests was the noise goes away when switched to 4x4.
