Bongo Fury

My van has just started to make a metallic rattle from underneath, which disappears with revs. Sounds like coins in a blender.

Any ideas please?

Sounds like it's coming from the indicated area here on photo

A lot of rattles come from the exhaust system and baffles in the silencer. The area highlighted is the output shaft of the gearbox, there isn't a lot to rattle as such in there and most noises would be related to road speed, might be worth checking the other side of the gearbox as there are a few mounting plates and bits that might rattle if loose.

Thanks Geoff
Will have a look around
