Can you buy rear bushing for knuckle on a,2012 ford explorer?

I suppose I could if I wanted to, but I don't have any reason for doing that. I don't own a Ford Explorer.

The only Knuckle on a vehicle is a Steering Knuckle in Front. On the rear you have trailing arm or control arm bushings and they can usually be replaced. Every now and then you need to buy the whole piece because the bushings are not available.
