Mine juddered from day1, especially bad on drivers side and noisy too
Persevered for a few months, cleaning screen and blades etc all to no avail.
Could have asked dealer to replace them under warranty but they would most probably have been the factory fit brand.
So purchased a pair of A864S Bosch Aerotwin Wipers for 20 quid and not a single judder since fitting them plus very quiet.
