Hi Rob,

Noise may be coming from the bearing. This was the case with my son's 85 240. Water had entered the mechanism. This was not apparent from an external observation.
The bearing is common to other manufacturers and is not expensive...$4.50AUS. I would expect $2US. The size was 6000 something. Can't recall from memory but have particulars at home if needed.

Repair requires some fiddling around. Removing and replacing the bearing requires some bashing and creative thinking. A soldering iron is also required.

your description sounds like the noise the wiper motor in our '86 240 made. The motor was loud and the speed was slow. I re-glued the magnet, cleaned and lubed the motor and made a new ground wire for it. Runs fine now.

Grinding, crunching, crushing sound. You can take apart your motor, remove the rust and paint it up with rust paint and then re-epoxy the magnets in their original places and probably get a few more years out of the motor. I did this once. It takes a while to do all that, so if you are close to a cheap junkyard with late model parts, it is easier to swap in a motor from a newer car. For $50, I would probably do this if the motor was from a car several years younger and with significantly lower mileage than yours.
