Here is the work

took out all of 6 allen bolts.
There is not so much space to fit good allen tools.
I used a standard 8 mm allen tool and turned the wheel backward ,quite easy.
Hammered out the little lock thing on the center nut.
Removed the big center nut with a 30mm tool.
Use large tools for the 30mm nut.

Now the pain begins.

How do i get the axle out from there ?
I tried almost every angle but it never seemed to be enough.
Finally i turned the wheels to the left and lowered the car completely and then there was enough clearance.

The rest of the job is cleaning and assembly and put it back again.
