I have a 2008 f150 lariat 5.4
i had the wheel bearings replaced with timken that I ordered off rockauto.
I ordered these because I was told the noise coming from my wheels were wheel bearings.
Had them replaced.
Still making noise.
Nothing is running around the bearings, it’s just sounds like a scraping noise but only when I hit the gas. When I’m off the gas it’s good, and when I’m going slow . When I hit the gas I hear this irritating noise like a cat clawing at the door.
Help pleas

Wonder if your 4x4 is trying to engage? Is it like a grinding noise? I'm not sure what cat clawing at the doors sounds like.

Put it in 4 wheel drive and see if it stops. If it does its the IWE's.

the brake dust guards rust and bend and scrape sometimes as they are falling apart. something else to look for

Awesome insight, thank you! I placed it in 4A which is sport mode.on my truck and as far as I can tell it stopped. So now, will.replacing tbe silinoid fix the issue or does the IEW assembly need replaced? I get it, start with the silinoid.

I'd start with checking for vacuum leaks in the system, but the solenoid and check valves are much cheaper and easier to replace than the IWEs.
