was at a juncton 2 days ago ,went to pullaway and the was a massive bang and the disco lost all gears first thought it was the clutch as it has been at hte top for a while , but the problem i have with that idear is that when you put in gear and drop the clutch it just sits there making a all mighty crunching noise/ it seems to be selecting difflock and hi lo has anyone got any thoughts on this matter
