Front suspension torquing up.

I have replaced most of the bushes on my front suspension plus all associated nuts and bolts,  and have now put everything back together finger tight. I'm wondering if there is a particular sequence I should torque everything back up, and whether anything should be left until it's back with it's wheels on the ground. I need to tighten:
  • Shock absorber top mountings - 30Nm
  • Shock absorber lower mountings - 145Nm
  • Wishbone to upper balljoint socket head bolts = 55Nm
  • Lower control arms to body - 90Nm
  • Lower control arms to radius rods/Steering knuckles - 20Nm
  • Radius rods to body - 100Mm
  • Anti roll bar to body - 20Nm
  • Droplinks to radius rods - 30 Nm
  • Steering rack to body - 25Nm
  • Tie rod ball joints to steering knuckle - 30Nm
  • Steering coupling disc - 20Nm
Thanks.

My drop link arms kept 'popping off' the end of the ARB when I tightened the bottom nut up when on axle stands, had to leave them loose until the van was back on it's wheels.

This was with poly bushes though so may be different with rubber?

Thanks shepster. I'm also using poly bushes. At what point did they pop off the arb? While sill on axel stands, or when you were driving ?

When on the axle stands, if you think about it the wheels are 'hanging down' with no tension on the drop links so when I tightened the bottom nuts they twisted and popped off the end.

Left them loose and lowered the van down then did them up, I haven't drove it yet but I can see they look a little bit more further on than when jacked up so I'm pretty confident they won't come off when driving.
