Thanks Mike,

You're right, the cupped washers on the strut rod either side of the rubber
isolator are to prevent overstressing the rubber in either direction.  Brett
should check that strut for free movement over its full stroke.  I've had a
Koni freeze up solid!  An internal urethane bump stop broke up and plugged
the valving.
