I don't hear the noise when I open the window and try to stick my head out the window. It has to be around 3k rpm and the motor under load since it goes away if I put the clutch in. Im thinking it has to do the the vibration of the engine under load creating a vibration that is rattling something
Hello all, I've got a 21 Gladiator sport s 6 speed manual. At about 3k miles I've noticed a rattle when I'm around 3k rpm in second and third gear mostly. Noise is heard from about 3k ROM to 3500-4000 rpm. The rattle sound is like a plastic on metal type rattle or even like a dull heat shield...
That's what mine sounds like, but I checked all the heat Shields. It happens at higher rpm on a flat surface too. So I don't think it's spark knock. Something is loose and only vibrates certain times that can't be consistently replicated and it's driving me nuts. Hopefully you find the fix too.
