Mettalic knocking noise?????
Ive got a five speed manual which makes a knocking noise when the car is moving and there is close to no load on the gear box - little revs. The other day, I jumped underneath and found that there was some free play up and down and in the axial direction (- it felt generally worn) where the tail shaft slides over the spline in the extension housing. Is this normal or could it be the cause of the knocking????????
