I have a right drive 1988 Defender 110. The wiper on my drivers side has been a little wonky since I got the truck a few years ago. I have replaced the female part and the wiper are a few weeks ago. I got some really nice wiper blades that are very tight in the window. I’ve used them a couple of time and everything seem kinda ok. But the arm on my drivers side does not always perfectly follow the other side that work. In a major downpour today. I turned them on high and the a blade on the drivers side started making a ratcheting noise and ended up almost off the window. I’ve torn everything else apart during my rebuild but have never had dash out. Wiper motor is still working perfect. But I can move the wiper outside with my hand and it makes clicking noises behind the windscreen. The shaft is moving inside. Before I tear this all apart. I would love some wisdom of what part or parts I may need or what trhe remedy is

Thanks in advance

your wiper wheel box is adjustable by bending a tab that forces the drive cable into the "wheel box" gear a bit more tightly.
The wiper motor turns a flexible cable with a worm drive type outer strand on the cable. This worm drive fits into a plastic gear in the wheel box.

Thank you. I took trhe defrost vent cover off where I could see it. Spray some lubrication down inside the area where the gear is and tap that flange down a bit with a blunt punch. It seems to be working at the moment, but I’m going to order a new wheelbox part. Just In case and remember to put Rain-x on more often. :). 👍🏻

Those wheel gears are caked with hard dry grease that feels and looks like wax. I had to remove/clean and replace with white lithium bike chain grease to get them to work properly.
