Hello again.
You will need to remove the wheel hub assembly, CV axle, and shock absorber. Here are a few basic tutorials for CV axle and wheel hub removal:

After doing so you will be able to remove the trailing arm assembly after removing the bolts shown in the illustration. After removal if you don't have access to a shop press you will need to take it to a shop to have the bushing replaced. The bushing is pressed in and requires extreme pressure to be removed and new one reinstalled. A press is what is required. I've attached the picture step-by-step instructions below for your car. Let me know if you have any further questions about this. Thanks for using 2CarPros.
