Tom,
TR 'wiper boxes' can be freed to spin easily again but if their teeth are
worn to points I would spend the money there. They should also have their
rubber
seal at the shaft intact to keep water out and lube in.
Otherwise many TR wiper parts can be saved ie; just flip the wiper's 'drive
cable' over for access to all new coil teeth. New brushes can be bought for the
motor (if needed) - then a relube may be all that is required.
Sometimes tweaking the bezels at the drive posts can bend the aluminum 'rack
tubes' inside but that's easy to straighten if you take all the guts out of
the air chamber.
The tedious bit is getting the wiper boxes out from under the dash.
Good luck,
Carl
