You have a upper and lower bearing that can go bad and cause this noise.
Its best to replace both when one is bad, both use the same bearing part number:
Bearing,upper & Lowe 28944RP
Also check the hub bearing, that could go bad too and cause this noise.
Here's the hub bearing/seal kit for your model:
766P3A Kit,hub & Lip Seal
You will need a couple special tools to do it:
321P4 Tool, Spr Hook
306P4 Tool-Hex Wrench
That's all you should need, it comes with complete instructions.
There is a video I located, but I'm not sure if its exactly for your model, but its very close:
