Replacing Griffith wiper drives

[Paxo1]

Anyone replaced the wiper drives ? I know it's a dash out job but I've had the dash out previously and it's not too bad. I need to replace mine as they are worn....is it a reasonable diy job albeit a pain to get at them ? Any tips from people that have done it ?

I was about to post you a quick fix, someone has already posted it here in the past and have saved me explaining
It is important to lubricate the wheelboxes (spray WD40 down them from their screen end) and make sure they are not tight or worn before following the below information
Also fit a new rack, if all is good this will save you much work

Taken from the below link. paulathome comments.......You will probably find that if you pull the cable out from the wheel box tube and then rotate the wheel box shafts 180 degrees then push the cable back in, everything will be fine.
Just lube the cable up with plenty of grease before refitting.
If you think about it only one half of the wheel box gear will have been used in normal operation. So if you rotate them half a turn then the other half should be as new. (well mine were)
Paul.

Good luck

Don't forget to mark with felt tip pen the original position of the wheelboxes spindles before pulling the rack (cable) out

Cheers for the reply Paul, unfortunately it's definitely the wiper box that's worn. I've replaced the rack with new and tried a number of different orientations of the drive shaft on the original box....it's still slipping unfortunately

Unless someone has already turned the spindles 180 degrees the above method should have worked
It is very unusual to have a spindle that has never been turned 180 degrees to not work when turned, perhaps the spindle has been turned in the past without it being marked before doing so and now there are worn teeth all over the place
Good luck in fixing it
