Wiper motor/rack slow

[Rob_the_Sparky]

As long as I've owned the car it has struggled to get the wipers across the screen when dry but now it is beginning to struggle when wet so thought I'd ask the advice of the masses

I was thinking about where the problem might be, I.e. is it the rack that just needs lubrication or is it the motor/gearbox that is at fault. Lubrication seems easier and I can imagine that the inner might slide out once the wipers are disconnected. Can this be done or is there some other way of ensuring the rack is OK before going for motor/gearbox replacement?

Brilliant thanks for all that, time to get to work

Another good wiper thread. OK it is old and not Griffith but what is being discussed seems to be relevant.
