Banging Wipers

[stark]

HI

So my wipers have just started banging on the bodywork at the top of the stroke and going way to far and banging on the bottom of the stroke. More pronounced at high speed wiping but still noticeable on intermittent.

Any suggestions on if anything can be adjusted to remedy this and if so how?

thanks in advance!

Sounds odd that they are banging top and bottom? Unless perhaps they have striped there mounts and are slipping on the now smooth(ish) mounts ? Is it both or just one wiper ?

slightly loose nuts so not fully griping shaft splines ?, wierd though i must admit

That's what we had. The banging of the wipers... and it was because of the loose nuts

Loose nut not fully griping spline normally leaves the wiper behind..? Had it happen on a Maestro belonging to my wife years ago.

Now when i first put new classic type wipers on the Bongo (not the aero type i have now.) the new plastic adaptor pivot was loose causing the blade to swivel on the end of the wiper arm in the "crook" causing them to swing a little wild on the ends...

Closing the gap in the crook solved the problem for me!

[MAZABON]

leaving wipers behind or wiper overswing both possible, depends on the tension of the spring at any given point on the windscreen, as i said though wierd

loose nuts in this weather would be very unusual , and certainly not leading to any banging

sorry mods

another possible is the whole or part of the linkage/mechanism has worked loose to cause the excesive movement in the wiper arms ?

Or you may just need a bigger windscreen...?!!

Na wont be just loose nuts, there are a couple of plastic lined ball joints which run in a slot, when the plastic wears out there is extra play in the movement,typically at the end or travel,you'll see it trying to move the wipers in the park position and see how far they move, when the plastic sleeve wears out and you flick wipers to max, they hit the body work on full position as the worn sleeve allows a little more movement, not sure if there's a fix, have only ever replaced the whole unit with unit with intact sleeves

hrm . Yep not the nuts as they were tight as you like.

I have the same problem - I have the chrome wipers fitted and thought that they could be too heavy ??

The wipers bang on the bodywork on the downwards stroke - not usually a problem as the stereo is on but when my wife is in the car she likes to chat and the wipers get on her nerves.

Now that I've managed to stop laughing at this thread, here's my thoughts:

1) I think if your wipers ARE banging on your bonnet, then you need to be careful. Bonnets are not intended for that sort of thing. Furthermore, if the car is in a public place, the wipers might end up nicked as a result of indecent exposure

2) Tightening the nuts on the wiper will not help it to grip it's shaft any better and may even prevent it slipping into its slot and being able to engage properly with the splines

3) If the shaft is not already in the spline, closing the gap in the crook (assuming the wiper is actually bent) will make entry impossible. On the other hand, if you close the gap after the shaft is pushed fully home, closing the gap should ensure the shaft is gripped tightly.

4) SPARKYSS has said that "The wipers bang on the bodywork on the downwards stroke....and the wipers get on her nerves". I think it is probably not possible for the wipers to bang on the bonnet on the upwards stroke and then be able to reposition themselves quickly enough to be able to bang on the bodywork on the downwards stroke. I'm old and slow mind you, so there's no telling what a pair of young wipers might manage. I'm baffled at learning the wipers get on his wife's nerves - I thought they were already on the bonnet, or the bodywork

5) Julian@321Away says "there are a couple of plastic lined ball joints which run in a slot, when the plastic wears out there is extra play in the movement,typically at the end or travel......when the plastic sleeve wears out and you flick wipers to max, they hit the body work on full position". I can see how flicking the wipers might make them bang very hard in a full-on position, but I'm confident when I say that it is not possible for the plastic balls (or their joints, or the nuts) to run in the slot at all, let alone to the end of their travel. I think Julian must be referring to the shaft.

6) I thinking banging on the bottom of anything, let alone the bottom of a stroke (not to be confused with a stroked bottom), is a recipe for trouble. I suggest you ensure your wipers don't do it, especially in public

7) I think Umbongocat has probably hit the nail on the head (or should that be 'the wiper on the bottom') when she says "The banging of the wipers...was because of the loose nuts". I'm quite certain that if a pair of wipers were to bang on the bonnet, and their nuts were loose, then they might slap against the windscreen. And that would certainly get on my wifes nerves. I know - we've tried it.

I hope this has helped to shed a bit more light on the problem.

Always here to help - you know me
