Installing New Leaf Spring Bushings

The suspension rebuild kit comes with leaf springs, and you install the front & rear bushings by pushing them in "eyes" formed in the leaf spring.  This is a challenge because the fit is very tight.  Here's what worked for me:  I put the bushing in the freezer for a few hours (cold metal should contract), and brought the leaf spring inside the house for a few hours (warm metal should expand).  I lubed the eye with white lithium grease, and then hammered the bushing in.  Seemed to go with 4-5 good hard whacks.  Some (not all) of the bushings have a very slight taper on one end, which makes it easier to get started.
