Yes cleaned everything as you say.

The mechanism has some play below in the mechanism cause by allowing the blade to hit the surround at some time. Impossible to get at to tighten up as it’s all under the scuttle and out of sight.

So have you any advice Yoke ?

yes, pop down your nearest Toyota dealer and get a pair, they're much better than Bosch etc, and not expensive.

Steve - if you accept this advice I would like to hear how it turns out. Wiper blades are not very advanced technology, and unless they incorporate a magic frictionless ingredient I doubt there is a great difference between them :-) The spring pressure from the arms is another parameter, of which the blades are independent.

Thanks for all your suggestions.

On closer inspection it looks like there has been some damage to the wiper arm support post.

When I lift the arm there is a click and the arm moves in the direction of the free play.

The previous owner allowed the blade to hit the screen side which over time caused the damage.

when I got the car i repositioned the arm but the damage must have been done.

The arm is firmly secured on the spline but the whole support has play in it .

Because of the age of the car I’m reluctant to dismantle

Thanks Andrew but the whole support spindle moves laterally when the arm is retracted onto the screen, signifying excessive wear.

Apart from replacing the whole mechanism is there anything else I can do?

ive had another go at cleaning the screen and blade.
