I did mine on the drive, give yourself enough time so you dont get stumped,
i used an alan key to spread or use a chisel downwards not inwards, if its springs only youll get new bump stops
so no cutting old ones, also when you pull the strut down out of the tunnel, just check on the top.. as mine had an arrow
on the top, that needs to go back pointing the same way ? dont know why. but check.
the rears, i took some pressure off the springs in situ my clamps where small enough, then when you drop the beam/arm down they pop out better.
have fun,
billy
