Juddery Banana Shaped Wipers

[Grandad]

My banana shaped wipers only operate smoothly when there is plenty of rain on the screen - normally they judder noisily when on constantly, so I have to set the intermittant to a long pause to overcome it, which is not always safe. I have changed the wipers to straight ones but without any long term improvement. The juddering seems to occur on the upward sweep of the blade when the curve of the banana is providing most resistance against the glass.

 

Could it be that there is too much pressure on the whole of the wiper arm from the the spring that holds the arm to the screen?

 

Is it possible to change the springs for softer ones?

 

Can I buy the whole arm?

 

Is it possible to fit the aero blades to an S reg 1998 2.8 v6

 

Many thanks

hmm...

 

I think the wiper arm has a 4-5" rod that is perpendicular to it at the base, that goes into the wiper assembly in what is a tube that itself is perpendicular to the 2 wiper assembly rods across the car.

Mo4 would be able to tell you better, but I think the 4-5" rod is bolted at the base of the tube and connected to the long rods.

I dont know if it is serviceable or removeable... although I have bought just wiper arms from a scrappy... but my story with the wipers is incredibly longwinded.

 

could you put something between the wiper arms and the tubes to change the angle that they are coming to the screen at ?

 

dunno.. good luck here

My wipers judder when the rainex needs re-doing.I now clean all my windows with auto glym glass polish and the judders go away. Just a thought. Tbag.

Try to establish if the wiper folds over at the beginning of each stroke, which will happen it the blade is at right angles to the screen.

 

I have corrected this on many a car by twisting the upper part of the arm with a pair of pipe grips on a trial and error basis. keep the pliers in the car till its accomplished
