I installed the new bushes (original BMW).
Then I started the assembly.
I bolted the 4 arms (aluminium ones).
Then I put back the axle carrier on the car.
Next was the differential ($*#$#*$U*#$U heavy !!!
)
There was a recall for the differential bolts of the M3 E46 & CSL, as the original bolts were breaking.
On the left the new bolt (it doesn't have threads throughout the length) and on the right the old bolt.
I installed the new bolts.
I also replaced all other bolts with new ones.
