Hi everyone.
Got an knocking/rattle coming from the truck when its fully warmed up and off throttle. Does it in every gear, neutral, but not when i engage the clutch or throttle on under load. There's nothing worn or loose externally, the noise is def internal coming from the bellhousing/oil sump area. Now i'm thinking this is either gearbox or bottom end, but I just can't pin point it.
Checked oil pressure, perfectly fine idle and driving. Here's a video of the noise.
