Hi guys and many thanks for your responses and the warm welcome.

FrankR, my car has relatively low mileage (currently about 57000 miles/ 91000 km on the odometer and has a full service history with the agents (this may be the root cause of all that is wrong with the car <img src="/forums/images/graemlins/angry.gif" alt="" />). The suspension is not lifted. In fact the car is pretty much stock standard at the moment (it is my wife's daily driver and I am not currently allowed to modify it <img src="/forums/images/graemlins/rolleyes.gif" alt="" />, but I am keen to get rid of the standard running boards and mud flaps for a start). The rear propshaft does have a splined slip joint at the transfer case end.

grass13, you are correct, the propshaft seems to be well balanced on the balancing machine.

FrankR, grass13 and TobyB, I will definitely look into the slip joint wear issue and report back.

Many thanks

Gerrit
