Thanks Chip, wow you tried hard to lose the rattle!! I'm thinking what the cause(s) might be, including the spacers rattling (although my rattle sounds harsher than plastic on metal), the splines chattering at idle as the revs fluctuate slightly......it stops when throttle load is applied) The spline arrangement is odd in that the gearbox end is "clamped", but the engine end isn't - why clamp one end and should it be clamped down tight or just enough to provide a tight but slide fit I wonder? I'm going to try the heaviest grease I can buy on the engine spine to see if that helps. Also I'm thinking to use some stick on heavy duty, foil backed sound absorbing material in the top of the torque tube to see if that does any good and that tube is a sound tube! Lastly does anyone know if the longer or shorter spacer goes at the engine end on the auto car M (completely different to manual)
