PS. Im not a professional mechanic(Im in IT). But changing a wheel bearing is'not rocket science either. Use this guide at your own risk.
So here goes...First on the list is secure the rear wheels.

Remove the wheel roundel


The 27 bolt going through the CV is normally very tight. Mine wasnt really tight. I used some q20 here to help loosen the bolt.

Go ahead and loosen the 27 bolt. Some might use a mutispline socket here, Mine was a normal hex bolt. Then loosen the wheel nuts

Jack the car up and put it on a jack stand. A jack is not a jack stand. Then remove the wheel.

Open the brake fluid reservoir.

Use a screwdriver like so and pull towards you to push the brake caliper piston in a bit.

I used a cloth between the screwdriver and the brake disc to prevent the brake disc getting scratched/damaged

Remove the caps over the brake caliper floating bolts
