Assuming you lubed the strut bearings. Anyway glad you fixxed it.

Toss another in the fixed bucket for the NE gearheads...

And I'm going to throw that into the "memory bucket". It is the first time that I have heard of that occuring only above a certain speed. It'* always been a low speed or stopped problem. Even now with it being fixed, it still has be scratching my head.

It'* the turning movement, the spring is sitting in one position and all of a sudden the weight transfers enoough... the spring moves quick and makes the noise.

Yep, but it would seem that at low speeds, where "stop to stop" turning is more likely to occur, that the torsional forces exerted by the springs would be greater than the downward force provided by the weight of the car.
