i bought a 156 2.4 JTD Sportwagon for my wife 6 months ago and a fine car it is until things go wrong. The alternator bearings broke up in September and it took 2 men 2 days to repair as the main engine support could not be removed. The cam and auxialiary belts were replaced while the car was in bits and all was fine for 4 weeks then the aux belt broke , it has just broken again 4 weeks later. All the pulleys are OK and appear to be correctly lined up, does anyone have any idea what may be wrong??
