woohoo! its taken me 2 years , i just stopped the juddering!
Thought i'd dig out the aeros and try them again , im thinking of selling the car, so thought i'd put 'em on...
As per usual judder judder judder, so, after a bit of googlisation, came up with this fix,,
park up, turn on wipers, when blades are in the 12 o'clock position on your windscreen turn off the ignition.
Your wipers should be parked pretty much in the upright possition now.
Get out of the car, now, the blades should cross sectionally be sat at 90 degrees to the screen, ie not leaning in either direction.
Remove blade at this point and if carefully rest the hook end of the arm on the screen, again you should be able to see if its flat on the screen.
Once youve worked out which way you need to go, get a suitable impliment, i used a largish spanner, put it in the hook and twist the arm so that it sits flat.
Replace blade and check its now sat at 90 degrees and enjoy judder free motoring.
It took me 10 times longer to type this than to fix the prob!
incidently if anyone fancies a 53 lcr, give me a pm..
