The old car project dick punch. Nice work Monte, ol' Mike never saw that one coming....
Did you measure coil spring diameter? Could they be the wrong springs? Loosen the lower arm mounts to remove possibility of bind? Turns out BMW has it as part of the suspension service procedure, I never thought it would have that much effect but it made a huge difference when I did the struts.
Seriously.
Right in the pisser.
These are the exact, literally, same springs as were in the wagon. They came out when the 5664s went in the wagon and got stuck in the 5664 box. I am baffled.
And yes, you are right, loosening everything up may have an effect. And the thought did cross my mind... I just walked away in disgust. I cannot say for certain if I ever undid any of the hardware when the chopped blue springs went in. Knowing me I just slapped them in and called it a day. I will make a point of breaking everything loose to see if it helps. Thanks for the intellectual and moral support.
