rain sensitive wipers

[Grant]

grease acting as a grinding paste?!

righto...must go out and take all the grease out of my wheel bearings then

wack a load of grease in there and warm the contact pins and then bend them ever so slightly towards the tracks.

then make sure you grease up the ball joints on the wiper mechanism while you at it.

I have done this on every pug me and my friends have owned as soon as ownership been done...improves them immediately and avoids future issues.

however if the grease has gone hard/old then the contact pins may have ground themselves away/snapped due to lack of lubrication reducing the friction...then you really need new motor or contact pins

PS this would all depend on WHAT grease you are using grant??

I think you will find that your wheel bearings are a SEALED bearing, meaning that nothing should enter or exit the environment the bearings are kept in.

In the scenario of the wiper motor, which we are talking about in this case, it is not a sealed unit. Water will drip from the wipers and windscreen onto it. As we know, your car is dirty and water will transport this dirt when the windscreen is wiped. Grease will trap and hold dirt, so any micro particles in the grease, will now act as a grinding paste.
