I recently had to replace the rear wiper motor on a 2011 FD hatchback, the wiper was moving very slowly and stalling in places. I obtained a 2nd hand motor to replace it with but found it impossible to pull the wiper arm off the motor shaft. I bought a puller tool, but it wouldn't budge even after tightening up the puller as tight as I dared, and applying penetrating oil, heat, tapping it with a hammer, wiggling the arm. Eventually I resorted to sawing through the shaft, then knocked out what was left of the shaft from the arm. Didn't matter as I was replacing the motor anyway.

It may be advisable to pull the wiper arms off the shafts every couple of years, just to make sure they don't seize on. Apply a smear of anti-seize compound, just to make sure the arm will come off when you really need it to.

That's great 'preventative' advice there BrendanP, thanks.

Strange that it should sit so tight on its spline and can't be removed with a simple left-right-left tapping motion.

Thanks, Brendan. I was expecting you to finish the story by saying you found a nut under the cap whose removal would have saved all that work 😨

Checked my car which is a gd and has same set up.

If mine did that and given how you eventually resolved I'd probably leave it as currently not an MOT item.

Thanks for the info. .
