My moggie makes a noise between 30 and 40.
It is a 948cc
Is this a gearbox issue or a prop-shaft problem. I have recently had the diff done and the prop-shaft looks like the casing is not long enough.
Help would be appreciated![frame][/frame]

Welcome to the Forum...... We need more information. What kind of noise? And 'diff done' - what was done - and by whom ?? And why was the 'diff' thought to be needing attention?? Sure the final drive is filled with oil? Are the prop shaft bolts tight? Has the prop shaft been greased in living memory? Is the rear axle sitting correctly on the springs - not sitting nose up (or down)?
