With a little right lock and going over a "down bump", say one of the many potholes we enjoy, a real boxy clonk. Straight ahead over any kind of bump. no problem as you would expect from a car of this mileage.
Read the forums and took it to my local Nissan garage were the receptionist kindly stopped chatting to her mate long enough to tell me she had never of this problem (!) and it would cost £45 for a technician to do a diagnosis.
Declined this and took the car to my local garage where the two technicians took time to listen to me describe the problem and look.
Left the car with them for the morning and returned to find they had had put packing between the lower bracing strut and the rear subframe bushes to stop contact between the bar and the subframe. The rear subframe bushes, like many others described here, had sagged to allow occasional contact. I will not waste time with Nissan as they seem to deny there is a problem. Cost £36 for the entire job. Go local......
