=====================

OK, along the lines of the above comment: I just installed a pair of Bosch
wipers -- worked fine for about the first day, then started chattering on
the upstroke, on the driver's side only.  It appears that that arm's spring
tension is too great, causing a set in the blade.  I don't see any obvious
way of lessening/adjusting arm tension ('89 100Q).  Am I missing something
obvious?  Is there a solution? (do I just bend the arm itself...?)
