My 1998 35 10 2.8 gearbox is very noisey when under light load between 30-55 mph. It has new clutch and release bearing. I understand there is a bearing on the main gearbox shaft could this be the fault? Is it a part or new box? The noise sounds like tapets but only when under light load, so no noise when no load or when under high load. All the gears work fine. Have changed oil (Iveco gearbox oil) Help

Hi so not sure its the gearbox now as if I dip the clutch and rev the engine I get same type of tappity noise. So It make this noise when I load the engin as soon as I let of the power the noise stops.

There is lots of bearings in a box,All replaceable,assuming u can find a mechanic that can or will do them.Weird description though.gbox noises are usually a drone or groaning noise increasing with road/engine speed,noise should get louder when on throttle.U have checked the propshaft u j's and carrier bearing yes?
