Rattling noise

[Bluelv702]

So when I’m driving fast and my rpms are above 3k I hear a rattling noise coming from the front right side of the car. Not sure if this is the turbo making the noise or what? Can someone help me out what’s going on and why it’s making that noise? Thank you.

Check the engine mount on that side. Also suspension components for wear. A bad endlink on one side will sound horrid but be a cheap fix for example.

Just a noise? Nothing vibrates? No weird bumping or feeling at the wheel or in the drivetrain?
If the turbo made a rattling noise, it would have blown up a second later. Your turbo is fine. They last as long as the engine with proper maintenance.

Yeah there’s a jerking when I shift at times where I can feel it

Yeah just noise when accelerating no vibration or anything like that

This is likely a separate issue, but the FiST has the same rear motor mount (RMM) as the base Fiesta. It is way too soft for spirited driving because the engine makes a lot more power than a regular Fiesta. You have to give it a split second to line up between shifts.
Replacing that inadequate piece is mandatory, if you want to shift this car in a spirited manner without hurting it.

Yeah I was thinking of changing the mounts to get them solid. But the noise I heard sounds like a blade spinning n grinding but also sounds rattling. Ima try to see if I can record it.

My psmm rattled and made noise without shaking the car. It just wore itself out.

The car doesn’t shake when the noise is being made. No vibration no shaking just something spinning n grinding when accelerating over 3k rpms. I thought it might of been the turbo but I’m new with the turbo thing so I don’t know anything about turbo. First car I got with turbo.

What other discussion is that? What’s the title so I can look at it.

He's good-naturedly 'busting' on you.

How many miles? Could be the tensioner and idler for the serpentine belt. A bearing might have gone in the pulleys.
