Why is the bolt facing engine down. Nut closest to the ground Reasoning behind bolt is supposed to be like that.

Hi,

I'm not sure which bolt you are referring to. Here are the directions for replacing the lower control arm. The attached picture correlates with the directions. Take a look at the pic and let me know specifically which bolt you are referring to. I suspect it is number 5 in the pic.

Hi,

I just went through the directions. I see nothing indicating it has to be a specific way. If it was mine, I would face the nut in the directions it would be most easy to access. Here are the directions right from Alldata:
