Brake backing plate

Just finished ordering car parts, including the rear hub for my
2002 Sonata.

When I bought the car, the seller told me it made a noise from
the rear, which he thought was the brakes. I replaced the
calipers, pads, and rotors all around. When I got the rear
passenger side apart, I found that it still made a noise even
with all the brake components removed.

The noise is a "rotating" noise, it varies with the speed of the
car and does not occur when standing still. It does not vary when
the brakes are applied.

".....shu......shu.....shu....shu....shu..shu..shu..shushushushu"

Anyhow, I presume that it is a problem with the hub/bearing
assembly and I have ordered a replacement. I wish I had replaced
it when I had the car apart <g>, but it was not on the agenda. I
don't really know if this is a problem or not, but the noise
affects my enjoyment of the car. Plus, I presume if this fails,
it will probably be on a long trip or other most inopportune time<g>.

When I was doing the brakes, I noticed that the steel plate on
this wheel was damaged and rotted. I removed a loose piece since
I thought maybe that was what was causing the noise. Since I am
now about to take this whole assembly apart, I would like to
replace this plate. However, I cannot find one on-line. I also
don't know if this is called a "baking plate" or a "splash
shield" or what. I'm guessing the Hyundai dealer can get it ($$$)
or I will have to get a pre-rotted one from a junkyard :-(.

Anybody have any helpful info, advice, parts sources, etc? Thanks!

 

It's called a backing plate. Assuming the reference to calipers and
rotors means you have disc brakes, the Hyundai part number for the
passenger rear backing plate is 58252-38000.
