Has anyone found a source for Polyurethane Front Suspension Front Lower Arm bushings? I may have to resort to the OEM rubber ones as a replacement for my torn ones. Looks like it's a replacement of the whole arm since it may result is lower cost than the bushings and labour combined. Is in Mexico anyway. These cobblestone roads (really boulders; think Cortez did the road build) and topes (speed bumps) kill the tires and suspension.
