Thanks for the replies in my other post. I got all the clips out in the end. Only broke one tab out of all of them! So got the cover off and squirted some WD40 up towards the pivot points on the arms. It now moves a bit better but sounds horrendous. I think one of the bearings either on the pivot or what ever the spindle spins in where it protrudes through the top of the bulkhead are near seized. It screeches like a rusty seized up bolt as you try and undo it. Does not seem to be freeing up any more either. hence I think I need to pull the mechanism completely out and try and investigate further. The question is how. I have a horrible feeling you are going to say one or both wings need to come off to get it all out? How does the motor separate. Also I am sure I read somewhere that you need to be careful to get the arms back in the right place relative to the motor positions. any tips on how to do that if I am pulling it all completely out? I suppose I could mark the position of the spindles on the bulkhead. then it is how I go about timing the motor?

Thank you

I didn't read everything... but mannually rotate the wiper arms up (about 45° should do it) to allow the motor arm to clear the mounting hole. This will allow you to remove the wiper arm motor.

 

I need to get the entire mechanism out to lubricate and free it up..
