steering knuckle / wheel assembly? wheel bearings? Options

[homebuilder]

Hi,

I have bad bearings in the front passenger side. I noticed online a rear wheel assembly for the same price as the bearings along.

Is there an assembly for the front?

I was told something about it being called the knuckle, can you buy that with the bearings already installed so no need for a press?

The mechanic I was talking to said the assembly or whatever holds the bearings was probably bad since the wheel bearings are making noise, and I may as well get and replace the whole thing. Now I know part of if not his whole reason for saying this is apparently it is less labor to just replace the whole knuckle compared to replacing the bearings... But what is yor experience? It only started making scrapping noises today, do you expect the whole knuckle to be bad?

Knuckle is probably fine unless it spun an outer race which is unlikely. It could have spun an inner race and damaged the hub though, I've seen that a few times. Have to take it apart to know though.
