So, I went underneath the car today to attempt to check on my wheel bearings, which I suspected to be failing as it is making a humming/whining sound when going above 60km/h and only to gets louder when the speed increases (And louder when turning one way, and less if turning the louder) Anyway, I discovered this leak on the front right hand side. It seems to me it's the boot of the control arm? there's a constant yellow fluid that is leaking from it.
It was only the beginning of the year when I replaced the control arm bushings and CV joint but that won't be related to this I presume?
Does anyone know what this might be? And whether it could have related to the (what I think is) wheel bearing noise?

Thank you.
