I went back to look at your pictures, first post pinned it on left front, later it pinned the noise on right front. Which one is it??

Either way, the dust cap is shown in your pictures. Yes, it's the piece that juts out from the center hub.

To access the bearings you have to pop that cap, just pry it off gently. It should be kinda greasy on the inside. The bearing will be retained by any of several methods (generic term for "I don't know how your's are retained"). You can check/repack the outers and retighten the assembly with out having to pull the calipers or rotors. To do a full bearing repack/replacement (inner/outer), you have to pull the calipers and rotors, plus replace the seal.
