if my 2019 Silverado sits a while (and as it's over a year old and has less than 4k on it, it does that often) it can make a whirring sound on start that goes away at varying times shortly after warm up. Cold seems to make it more prevalent......and it changes pitch with revving the engine. link to vid here (apologizing for my stupid voice being so loud in advance) you guys have any idea? I thought it was maybe power steering fluid but apparently these truck are electric steering? also, the noise can be heard a little more from the wheel well than the top of the engine with the hood open

Where are you guys getting Bilsteins for the rear? I can’t find em anywhere. I desperately want shocks for the rear. 2019 Silverado
