Review on 🔎 Optimized Motorcraft YG360 Vacuum Inspection Switch by Ken Arellano

I have a 2005 F-150 FTX that has a squeak and crackle coming from the front. It was very intermittent and difficult to follow. Sometimes this did not happen for months, then several weeks passed with varying rattle volume. It took me a very long time to figure out what the problem could be, so I started with an IWE vacuum solenoid and two vacuum check valves. Considering the cost, all three were easy to replace, but when I checked one of the old valves it was clearly failing. This new check valve 100% solved my problem, although in the future I may need to replace the hub drives, it eliminated the squeaking and rattling noises coming from the front.
