How's it going?
Jack up the back of the car and spin the wheels by hand, you should be able to hear a grinding noise. I think if the noise is less when turning left it could be your rear left because there would be more of a load on the right hand side when you turn left. Does that make sense? I have done a couple of them using a threaded bar to jack them out and refit the new ones. Its easy enough if you take the trailing arm off.
