Old '94 dodge duckodor, windshield wiper arm keeps popping off. Always the same end, drivers side transfer arm, from the motor, to the common linkage, ,at the driver's side pin. What a godawful tiny little box to work in. Almost busted a knuckle, tryin to get the arm back on, after I gave it a coupla love taps, with a bfh, to tighten that everlovin plastic bushing up, in the arm! Got to thinkin, this thing ain't gots no warranty left on it, why kill a handfulla good knuckles, tryin to put it together for the 4th time! Took a hand grinder, with a cutting blade, and made me an access door, about 2" square, in fronta the wiper spindle, like the mfr shoulda done, when they built it! Took alla 15 minutes to do it, can now see what I'm doin, and with alla this experience, now I bet (knocks on wood!) I could do it under a bridge, on the side of the hiway!
