On way down to catch ferry drivers side wiper stopped, then a few minutes later the other one. I have had the problem before , nuts tightened down with spring washers. Tried putting loctite thread seal but this hasn’t worked. The spline on the motor post looked a bit worn but not awful. Any quick fixes until I get home. Don’t really want to araldite it for obvious reasons. Maybe the wiper arm itself may have worn so will try to get another .
It's a pain that. I've carefully cleaned up the splines as best as poss in the past and proper tightened them down, obvs whilst the wiper is hinged back to take the pressure off. Try one of the excellent continental motor factors for something like Rainex maybe. Wynn's have a French distributor for Rainex Europe. Fingers crossed you won't need them
Are you sure it’s not the splines on the wiper arms that are worn? I have seen the aluminium wear and fill up the teeth. A sharp object and try and clear them out?
Yup in the UK. Huyrobs on a continental jaunt at the mo, so maybe he can source it in Spain and splineage as above...
Once the arms wear to a certain degree you can end up with the nut tightening against/bottoming out on the shoulder of the spindle leaving the arms loose. New arms or temporarily maybe try wrapping some silver foil or something around the spindles.
Serious suggestion: wrap some PTFE tape around it? As above, more likely to be the soft wiper arms rather than the steel shafts.
You can bottom out on the thread when tightening up. Adding an extra washer or two brings you back up to good thread so the arms will bite properly on the spindles.
It's been like that 15 years. From slopping around helplessly it's been fine and the cap covers it all up.
Use araldite. A sharp tap will crack it when needed. e.g. Put a spanner under the end of the wiper arm , spanner jaws holding the spindle away from the panel, lifting the arm from the panel. Loosen the nut to the end of the spindle. Tap the nut with a small hammer. . As both the arms and the spindles are probably now knackered you might as well glue them. You can obviously get new arms and spindles, for around £100 you can have all new. E.g. coolair.
