2021 Powerboost Platinum FX4 Kodiak Brown.... Oops, I mean 2022 Powergrid KingRanch in Shiney White
I bet you are right on. (beware me agreeing with you. That may not bode well)These engines are not always pulling a vacuum and best I can tell this check valve prevents the boost from releasing the hubs and allowing them to lock.
I will say the title of your thread threw me though. That nasty misbehaving IWE sound isn't so much a rattle as it is a clicking, and then can advance to a grind.
Regardless, doesn't feel win win when the solution is 10 bucks!?
