I have read on here that removing the bobbins can be a challenge. Mine are intact but all have quite a few cracks on the surface. Having read that a few of you have had your pipes actually fall to the ground, am thinking prevention is worth the effort. However, mine are stretched at a decent angle, as if the top and bottom mounts are not well-aligned. Do others have this same fitment issue? Mine is a 2016. Any tips? And where are you sourcing your replacement bobbins? Cheers.
