I also find WD40 is a temporary fix. Is there a guide to removing the handles ? Do you have to remove the whole door inlay from the inside first ?
yep. take the door card off, not that difficult
take the speaker cover off, remove 4 screws for speaker, then 2 more screws behind that.
one behind the blanking plug for the door handle cover/tweeter housing, slide that off.
pull off the cover at the front, opposite/behind the mirror if you see what i mean
no screws, just clips give it a tug.
take out the cover in the bottom of the door closing recess, 2 allen/torx screws under there (can't remember if allen or torx, know there are allsorts in there). unplug the window switch connectors, all colour coded so you can't go wrong putting them back
then remove the 2 10mm nuts that you can now see
unscrew the door lock button, not 100% sure if that needs to come off but i always do
that is everything, but it was a coupld of weeks back and my memory is useless
start along the bottom and pull the door card away from it's clips along the bottom and both sides. when it is all free lift it all upsliding up the window so it comes off the top guide.
inside the door take the 3 or 4 screws from the black plastic housing and drop in the door bottom. then the 2 10mm nuts that hold on the window guide runner, again leave in the door bottom.
the door handle itself is held in by one 10mm nut from inside the door and one screw from the door end, think that might be the torx one
the link rods need unclipping, the long one pulls out at the top with a good pull, can't recall about the other one (or even now if there was 2
bit of a fiddle to get the whole handle out of the door, but it will come out, just be VERY careful not to scratch the door
once the handle is out you will find all manner of gunge & grease in the back, clean it out with carb cleaner or anything like gunk/de-greaser that will shift the mess.
once clean and dried then i put a small amount of thin grease, almost oil, inside. put don't skimp on getting it working smoothly before putting it back in, now you've got this far it needs to be right
build it all back up and smile everytime you go to the car and press the button in, it feels so much smoother and comes back out EVERY
time, no need to reach for the WD40 and get streaks down the door anymore
