Greasing right drive shaft outside joint on x300

Am I the only one having trouble greasing the wheel side u-joint of the right driveshaft? I have had problems with both then x305 and the x300.
The other three u-joints are straight forward, but on that one the coupler only fits at a slight angle. It is almost impossible to press grease out of all four sides. I am wondering if this is because the garages who did the maintenance before me gave up too soon, and now there is loads of old grease stuck which doesn’t get out.
What usually helps is driving for a while after the first attempt and then trying again.

It’s this just me, or have others noticed this as well?
