Patrick,
The operative word here is "Dominant". If the sound is there all the time, it
would indicate a likely U-Joint problem. But if it is "Only" there on
acceleration (one clink), deceleration or braking, that in my mind would
eliminate the U-Joints as a source of the problem.
Further. If you are under hard acceleration, it might keep the U-joint in an
attitude where the flex is confined and the sound is not there. BUt as soon as
you reach a cruising speed and the acceleration pressure is removed from the
u-joint there would most likely be a constant (albeit lower volume) clicking
made as the joint rotates.
But my understanding of the symptom is that there is only a single clink on
acceleration and another one on deceleration (and braking), indicating that a
fixed rather than rotating part of the suspension is loose.
Regards,
Joe
