I had another thread going called "one arm wonder wiper misses a spot". It misses a little pie shaped area to the drivers left. I have put in a new insert from the dealer and that reduced the are of the missed spot about 50%. I looked up the specs on the arm and there was a spec for clearance from the "gearhead" to the windshield of 5 to 8mm. Mine is around 9 so I tried to adjust it using the vague instructions from AllData "slacken bolt #2" and I could not improve it. I had a suggestion to put on a new blade, and I have no opposition to spending the 30.00 or whatever, but don't really see how that will help. I have a theory about the plastic "spine" of the insert binding slightly with the "claws" of the blade but not sure how I could really lube these areas. The windshield has been replaced but I don't think they have to mess with the wiper mechanism to do that. If you want to bump the old thread that would be fine with me. I think it was last active about a week ago.
