Windshield wiper thunk, thunk, thunk...
'95 LS400 w/240,000 miles. Heavy rainfall on the way back from Portland yesterday with the wipers FULL ON and going THUNK..THUNK...THUNK......
3 hour drive....Irritating to say the least.
Driver side wiper linkage arm was striking the passenger side wiper arm just before travel reversal from the bottom/park position.
Solved some of the slop by removing the bronze bushings from the wiper motor gear reduction output shaft and reversed their position and rotated each 90 degrees.
Still have some slop in the two linkage arm's nylon ball/socket retainers and cannot find a replacement source for those. Two type of ball-retainer sockets.
Anyone know of a source..??

Spent much of the time trying to tighten up the slop in bushings and bearings to prevent teh over travel.
In the process of trying to position both wiper arms for least interference possibility I noticed that the passenger side arm had a strange indentation, design, just exactly where the driver's side arm was striking it. On a guess to the purpose, intended purpose, of the indentation I took a hacksaw and cut a section out of the passenger side wiper arm that exactly matched the otherwise needless indentation.
Viola...!!
It worked.
My guess is that someone screwed up a CAD file design aspect somewhere along the way.
