Those videos you posted sounds like a failing power steering pump to me, you also mentioned a stumble. When the PS pump begins to fail it can place a load on the engine to either make it stumble, or worse the pump will lock up causing the engine to stall and not run. If people are not careful enough when they do mods to that area around the pump it can let air into the system causing those issues.

I might have a log or two only since my last custom tune but I've only been tuned on flrx for a couple thousand miles. Also, the oil was changed about 500 miles ago (2 weeks).

This is a possibility as I've been having weird issues especially when the car was cold.

yeah, it just sounds like a failing PS pump to me. Usually when a bearing goes you hear the clacking noise at idle.

Also sounds like a lot of whine from the alternator. Is the belt super tight? Did that maybe affect the power steering pulley since they share a belt? There should be a few mm of deflection in the belt between the crank and alt pulleys.

Based on the videos you provided, this sounds like a power steering pump issue. Normally when you spin a bearing, the noise is a very loud knocking/clanking sound at idle and all throughout the rpm range. All i hear in your video is the classic power steering whine of these cars when the pumps are on their last leg. I would recommend replacing the PS pump, bottle, hose, fluid, and maybe even replace the belt while your there.

Thanks everyone, I'm 100% sure now I spun a bearing. It seems I have Power steering issues as well because the fluid looks burnt.

Check the engine oil level.

Oil level was perfect and I had just changed it the week before with Mobile one 0w40 Euro blend.

Hopefully I'll have the car back next week sometime.

Agreed!
Monitor the knock. It's always on the bottom right on my Accessport display. You never know if you get a bad tank of gas!
The stock bearings are slight. 180,000k and mine worn through the first layer.
Now running 10W40 oil for break in (EWG WFO).
I plan to run 15W40 for up to 15lbs boost. 20W50 for 22lb track days.
