Sticky wipers & service manual

Hi there,
Just got a disco2 and loving it! One small issue is juddering front wipers. They judder and sometimes don't park properly. I suspect it's just a case of pulling g the rack and cleaning & greasing but are there any well know weaknesses or common causes?
Also, for a service manual, is the Haynes any good or is there a better one to go for?
Thanks!

Don't know about your wiper trouble, check the linkages would be the first advice from anybody.

The Haynes manual is ok, not even OK, some around here refer to it as "the book of lies". Most will tell you to use the Land Rover workshop manual. It can be downloaded free from:

Just what I was looking for! Thanks!
