Rear A-arm bushings or wheel bearings
 

I noticed that when shaking the rear wheel there is play which seems to be in the A-arm bushing on the right rear tire. When driving I hear some sort of low pitched noise coming from the right rear which sounds like when your belts shift in your tire. I'm going to rotate the tires around and see if it follows that tire. I had belts shift in my goodyear tires in the past and that's what it sounded like.

My question is how hard is it to change the A-arm bushing on a 95 se? The book says something about a special tool to press the bushings, is that true?

Could my rear wheel bearings me making the low pitched sort of grinding noise that I hear? I have close to 200k on the rear bearings.
