What on earth did I do?

Last time out I felt a little vibration through the steering wheel at 65mph. So last night, with my oldest son the drivers seat, we did the requisite steering linkage checks, everything looked good. Drop arm? Check. steering rod-ends? Check. Wheel bearings? Check. Panhard rod bushes? Check. SPH preload? Let's do that last....

Just by chance I grabbed each shock. They easily rotated in my hands, and the top of the RH shock was physically loose. Trouble was, the lock nuts were tightened and bottomed on the stud shoulder? Pulled a set to check at the parts store, and looked-up the part numbers for a LR parts order.

Early this AM I find this:


The shocks are basically brand-new. However, they were installed the the bushings flipped 180 to the drawing above. This caused the bushes to nest into the cups/washers, and allow the nut to bottom without compressing them.
