The heart of my wiper problem turned out to be the plastic bushing between the wiper motor pivot arm and the wiper linkage. Typically held in place with a "C" shaped retainer.
Mine popped loose and allowed the wiper linkage to mangle it.
Jeep dealer does not show this bushing on their diagram for the wipers? I cruised all the usual on-line guys. Even went so far as to buy a "wiper bushing kit" from the local parts guy. Their kit has the arm bushings but I don't see the one I need in the kit. Will double ckeck tonight.
I put a feeler out to two of the on-line wrecking yard used parts places.
Any ideas on a solution?
