Squeaky Wiper Arm

[littlemissmagic]

Have removed arm from motor, has resolved problem, so can assume it's not the motor.

Sounds like metal on metal, have tried lubricating all visible moving joints - still squeaking!

Any ideas please?

lubricate the wheel box
remove wiper arm
remove circlip from top of wheel box and rubber seal then lubricate down shaft
