2022 F150 IWE issue (rumble strip vibration noise)

[Jerome10]

Just wanted to follow up my truck didn't make this noise even once this winter.

Never had the TSB performed.

Wondering if there may have been an OTA update or something that took care of this. It was happening very frequently last winter.

I ordered and picked up an electronic IWE for my 2021 F150 as a backup part.
To my curiosity, I disassemble the part, and it is easy to disassemble and re-assemble it back.

To my understanding, it has a motor to rotate the whole plastic rack up and down for the metal hub with teeth to move up and down to engage or disengage.

The plastic rack has a grooved track alone its side, and the track has a wave type of curve. This is the mechanism when the rake is rotated by motor, the rack will go up and down. And it has three small magnate, I believe they are for sensor to detect its position.

Therefore, there is no way this IWE is unable to engage or disengage. Unless the motor is not driving, or something is broken or not aligned properly.

So if there are grinding noise because of the IWD, I believe it is more relating to motor/sensor, it has nothing to do with thick grease.
