115k miles, the radiator and water pump were replaced about 40k miles ago. So that's all relatively new.

I noticed a drip coming from the passenger side, almost right next to the tire. Checked up top, and everything looks clean, but below is another story. Looks like the subframe has tons of corrosion and this has probably been going on for a while. Given the newer radiator and water pump, what else could I check that's on the passenger side?

Appreciate any/all insight
