Ogier does drive much less sideways than others on gravel. Would think that has an effect on the mechanical parts.

After Tanak came to Hyundai the behaviour of the car changed a lot. From hard-brick like suspension into much more "moving/diving" like Toyota was before that. It seems like this made the Hyundai much faster in faster gravel rallies, but maybe also more vulnerable to mechanical damage from rough surface.

There was also a nice comparison of Sordo and Evans om the last stage before PS where Evans goes "slowly" with a hint of understeed into corner and then a bit of power-oversteer out. Sordo was entering every corner sideways.
