Hi guys, A serious mystery vibration has arisen with a Mondeo 2.5 litre V6 I'm currently using and it's got me beat. I'm just wondering if anyone can speculate as to what the problem might be... Firstly, it's not there all the time; it comes and goes. When it comes it seems to show up at around 50mph and just keeps getting worse the faster I go. It happens under both acceleration and also on the overrun, even when coasting to a standstill and is still present right down to practically zero MPH and is in synch with the speed of the road wheels. When it's there it's *really* bad and the whole car shakes quite disturbingly like as if there's a wheel coming off! I've put the car through two MOTs and it's passed no problem; the wheel nuts are tight and when spun by hand on jacks there's no sign of any imbalance in either of the rear wheels (it doesn't seem like there's anything coming through the steering from the front so I assume it's a rear-end problem. The car's not been in any accident; I've had a friend follow me from behind in his car whilst it's been happening and he says there's nothing untoward going on as far as he can see... and yet inside it's pretty bloody scary! I'm baffled as to what on earth could be the problem. Has anyone any ideas?
