All,
I've got an '82 Scrambler, and it goes through wiper motor links (the short piece between the wiper motor and the left-hand wiper) every year or two. I can tell that there's stress on the link when the wiper changes direction, but no amount of wiper motor position adjustment eliminates it. I even tried expanding the range of adjustment.
After replacing the arm again, and tossing around a few ideas, I noticed in my 4WD catalog that the older Jeeps ('41-'68) seem to use one motor per wiper blade, and a direct drive mechanism. Has anyone tried fitting these to a newer CJ? From the catalog, I can't tell the dimensions of the motor or the wiper arm.
Thanks.
