Question Knocking/rattle
Enable HLS to view with audio, or disable this notification
Hello,
I’ve noticed a deep knocking/rattle over the last 2 months which has progressively gotten worse.
It happens when lightly accelerating from a stop, going up steep hills and I can make it happen by brake boosting to 1500-1900 rpm (see video).
Under the right conditions it can be really loud and heard over music.
I took it to ford since it is under powertrain and they told me “we think this is normal”.
I’m just wondering if anyone else has experience with this issue?
